Stair Section Detail Level in Revit

Here is yet another problem with Revit Stairs that really needs to be fixed by Autodesk:  

The view 'Detail Level' display in section is not consistent between walls, floors and stairs (not to mention ramps!):

View Detail Level


When a view is set to Medium or Fine detail level, sections of most categories display the correct materials:

When the View detail level is set to 'Coarse', the cut hatching display of some elements is overridden by the Type properties 'Coarse Scale Fill Pattern'

This capability is available only for certain categories - meaning that the display of stairs is pretty hopeless at Coarse scale

 


Workarounds

What to do about this?  There are several possible ways to resolve this lack in Revit, but none is very good!

Visibility Graphics

You can over-ride the cut pattern of stairs - but this requires several steps (excuse the pun) on top of just changing one View Detail Level setting:

Due to the fiddly nature of changing this in the view (similar settings may need to be applied to other categories), you would certainly need to include this as part of a View Template - so it could be applied or removed at the flick of a switch.

Filters

You could also try using a View Filter, as it could potentially be applied to multiple categories

This has an advantage in that it is more "discoverable" than searching through all the category overrides - unless you have a gazillion filters applied!

Another advantage in Revit 2021 is the ability to "Enable" or "Disable" the filter without losing the override settings - a very useful new enhancement for Filters.

Downsides

The View Detail Level is very easy to switch on/off - and it affects all categories that have the built-in Coarse Scale override capability.  If you set the view back to Medium, the 'by category' cut pattern overrides get left behind - so you would need another operation to remove those (hence the need to use View Templates).



Another problem with the Visibility Graphics workarounds is what happens when you choose anything other than black solid fill as your hatching override:

If you make it grey . . .

 

The Stairs will show the joint lines between different materials - you may or may not want this, but it is clearly different behaviour to the Coarse Detail Level control that hides the material join lines and treats it as one material, for a nice clean look.

Of course, this is not helped by the inability to join walls/floors to Stairs !!  You still get the joint lines between those.  Refer to Stair Joint Lines

The Worst Workaround

Filled Regions are extremely useful for patching up Revit's inadequacies, but they are not popular with BIM & Model Managers because they cause so many other problems as soon as a model changes.

Filled Regions allow you to make the hatching look exactly how you want, because they allow some of their edges to be "Invisible Lines" - thus they can appear to join with adjacent "real' cut hatching.

Filled regions are placed per view, so if you have multiple sections cutting through the same or similar parts of the model you may end up with many filled regions.

One possible method to manage that problem is to include them in 'Detail Groups' - but they are also problematic to manage, not to mention a major shortcoming of really slowing down your Revit model if you have too many of them.

Conclusion

Whichever workaround you use the most important thing to do is to follow company standard procedures - and be consistent.  Agree with your workmates on which dodgy workaround to use, and stick to it.  This will make it so much easier to come back to make changes when the model is updated.

Revit Stair-Floor Joins in Section

The inability of Stairs to properly join to floors (or other elements) in Revit has long been on the wishlist of things for Autodesk to fix.  Back in v2014, we were very excited when Autodesk included this in the list of enhancements to be released.  As per many recent Revit enhancements, this was only a partial improvement.

You can be the judge as to whether it was "fixed" but most Revit users are not even aware that anything changed in version 2014, such was the hit-and-miss nature of the improvement . . . .

Join Geometry - Stairs in Section


At the base of a stair, if a concrete monolithic stair sits on a concrete floor, you would expect to be able to join them, providing they are of the same material.

Well, you can  . . . .  sort of.  It only works if the stair base is sitting exactly on the slab . 

Join Geometry


The circumstances in which it works are limited, as you can see below:  

  • If the base of the stair overlaps the floor at all, it won't work - the join is ignored.
  • OK, you wouldn't normally lower your stair like this as the base riser height would be wrong
  •  But you might extend the run lower, by selecting the "Run" (not the whole stair) and changing its 'Extend Below Riser' property
  •  The join still does not work

  • So why would you want the stair to overlap the floor?
  • Well, maybe you have a screed on the floor slab, and you want the concrete stair to rest on the slab, not on the screed.
  • With the stair sitting on top of the screed, the join does work, although it shows a thin line due to different materials - but the structural geometry is not what you want

  • As soon as you lower the base of the run, the stair cuts through the screed as it should, but the join stops working - there is a heavy outline between the stair and the concrete slab (same material).

  • Many experienced Revit users might want to separate the structural slab from the floor finish (screed) - particularly when producing 'concrete setout' drawings or when collaborating between architects and structural engineers.
  • The concrete slab could be set down by 50mm (screed thickness);  
    • Extend the run 50mm below the finished floor level;
    • Join the stair and structural slab 
    • Add a separate floor on top of the slab - just containing the finish (screed)
  •  Not surprisingly the finished floor will run through the stair

  • The stair will obviously not join properly with the floor finish as they overlap each other

Workaround

  • Just for due diligence, I thought I should test the process by trying to join the stair and the floor finish
  •  This time it actually gave a warning, saying that they cannot join

  • Much to my amazement Revit did actually join the stair to the floor finish, exactly how it ought to - despite the warning !

  • Just to make sure, I had a look in 3D - and it really had cut out the floor finish - albeit with a permanently attached warning in the list.

  • I think I could live with that warning, along with the hundreds and thousands of other spurious ones that we are unable to remove or flag as not significant.

Edge of Slab Join

In some situations, the bottom of the stair could meet the edge of the floor slab


  • Obviously the stair run needs to extend below until it meets the slab edge

  • Join Geometry ought to merge the two elements

  • Apparently it does not.

Workaround ?

Oops, sorry I don't have a real workaround for this one.

You could try using the linework tool with invisible lines, but that has annoying limitations:

  • In section, the linework tool does not have grip handles at the end of selected cut lines - it makes the whole line invisible [Lines that are in surface/projection in the view would hav grip handles so that you could make part of the line invisible]

Then you would have to add detail lines back to the missing parts of the cut edges.


Top of the Stair?

What happens at the top of a stair when you try to join it to a floor/landing?  That is a whole different story, for another blog post . . . .

Revit 2021.1 and Load Autodesk Content

Revit 2021.1 was recently released by Autodesk - for those waiting on the first 'point release' before upgrading to Revit 2021, this might be time to go for it.

But wait - there is a new feature in 2021.1 that you need to know about:

"Load Autodesk Family" Technology Preview

When you install Revit 2021.1 there will be a new icon on the Insert tab:

 

'Load Autodesk Family'

This is a "Technology Preview", which means it is a finished product that is released early for any Revit subscriber to test - refer to the Autodesk Blog.  It is a cloud-based (only) tool that lets you search for and download the latest Autodesk Revit families - but it is currently restricted to that content only.
 
If you click on the icon it will firstly ask you to log in to your Autodesk account - that means it will only work with named licenses (which Autodesk is forcing us towards anyway).
 
Once logged in, the Technology Preview dialog box opens:

This content is located somewhere on an Autodesk server(s) - at this stage we have no ability to select where the content is.  We can assume that this will eventually be expanded to include other content in locations that we can choose - it is not clear whether it will have to be on the 'Cloud' or our own company servers?

This content can be filtered and searched in a number of ways:

1.  First choose your region, from the World icon


2.  Filter by Category - but sadly we can only choose One category at a time or All ('Any') - surely it would make sense to be able to choose multiple categories?
 


Search

Families can also be searched for by category name or keyword:
 




 
The resulting list of families can be viewed in a grid or a list, by clicking on the list format icon:

 


Well, what do you think?

If we had been offered this by Autodesk about ten years ago, I might have been excited - but I think that Autodesk are about a decade late to the party.  There are now so many third party content browsers out there on the market that it seems very strange for Autodesk to put any of its valuable development resources into this product at this time.  Most of those third party solutions already offer way more capability than this Technology Preview - it has a huge amount of catching up to do.
 
As noted, this is currently limited to Autodesk content.  Most companies have a policy to use only approved content - and that excludes Autodesk families and most third party families.

As a BIM Manager, you will almost certainly want to prevent your users from accessing this Technology Preview.  Luckily the Autodesk development team listened to the beta testers, and they have provided us with a way to disable the 'Load Autodesk Family' icon:

Add the following to your company Revit.ini so the button and the technology preview will not display:

[Misc]
ShowLoadAutodeskFamily=0

Make sure that you do this before you roll out any version of Revit 2021 - even if you don't yet plan to install 2021.1.  Then it will be in place in advance.

Get Autodesk Content

There is another new icon in the 2021 Insert ribbon: "Get Autodesk Content"

The purpose of this is for BIM Managers to be able to download the Autodesk content that is no longer part of the install process - refer to upgrading to Revit 2021
 
If you click on this button it takes you to the content download web location.  
  • Scroll down and find your region content.

  • Select either Family or Family Template content, and download:


Obviously you do NOT want your users to be doing this!  This is either a BIM Manager task, or no task at all if you don't want the content - most likely once you have developed your own company content.   The only exception is that you may want the latest family templates because Autodesk have a habit of sneaking little updates and fixes into the family templates.  The only way to get some of those fixes is to use their templates and recreate your own from those.

Currently there is no way to disable this functionality in the Revit.ini file (Revit 2021 or 2021.1).

10 Years of Revit Architecture Enhancements

In this blog I have analysed and made comments on various Revit Architecture enhancements over the years.  With all the recent talk of subscription value-for-money, I thought that now would be a good time to list and analyse the yearly enhancements to core Revit and those specific for Architects (my field).

Major changes to the software occurred in v2010 with a radical change to the UI (the ribbon) and a whole new conceptual massing environment.  Further improvements have been made to the massing tools each year but no attempt has been made to bring the traditional Revit environment into line with the new Massing environment – they continue to diverge, which is problematic.

Here is a summary of enhancements to Core Revit and Revit Architecture only (API, BIM360/cloud, MEP & Structures enhancements are specifically not included):

Classification:

This method of classifying the enhancements (by colour code) is subjective, and is based on how significant each change is to workflows and the impact it had on day-to-day usage.  Significant new features that only get used once or twice a year by most people do not count as major enhancements (“Shiny new toys”)

·      “Shiny new toy” – a  gimmicky tool of more use to the Revit marketing team than customers (not to say that we don’t ever use them)

·      Major Enhancements

·      Moderate Enhancements

·      Minor Enhancements

·      Follow up fixing & tweaking

 

V2010

·      The “Ribbon” interface – this was not requested by users, and was disastrous:  very clunky, slow and unstable

o   This was Autodesk’s attempt to modernise the UI and make it consistent with the new but "iffy" ribbon design by Microsoft.

o   The old Revit UI may not have looked elegant but it was very fast to use.

·      Conceptual massing – great new tools but hard to learn and incompatible with the rest of Revit

o   Refer: https://revitcat.blogspot.com/2013/12/rival-revit-environments-traditional-vs.html

o   The old massing techniques used the same 3D modelling tools as the rest of Revit – simple, consistent but limiting for complex curved geometry (No NURBS or lofting)

o   Autodesk tried to make the UI simple (like Sketchup) but that introduced its own limitations, which we still have 11 years later.

·      Numerous small enhancements, not listed here.

V2011

Reference: http://autodesk-revit.blogspot.com/2010/03/whats-new-in-revt-architecture-2011.html

There were no major enhancements in this version, but a lot of work was done to clean up after the dramatic changes in v2010

·      Adaptive Components in the Conceptual massing environment – great new tool but not very compatible with the rest of Revit

·      Reporting Parameters – great but many limitations (in formulas)

·      Linked model & workset improvements

·      Conceptual massing improvements

o   Edit form and sketch mode

o   Dissolve form

o   Divide surface by intersecting planes & lines

·      Ribbon UI fixes – stable but still clunky

·      Modeless Properties Palette (and a few resizable dialog boxes)

·      Graphic display improvements (Direct 3D)

o   Realistic and consistent colour views

o   Ambient Occlusion

·      Minor enhancements including:

o   Rendering multi-core

o   Rendering image background

o   Select all instances by view

o   Dwg Export improved

o   Sheet Guide Grids - sadly this never solved the view alignment problem

o   Text boxes and better leader placement

·      Analysis – Sun path tool ported from Ecotect

·      Web-based help files - this was disastrously bad – and took several versions to fix

 

V2012

Nothing specifically for architects in this version

Reference:  http://autodesk-revit.blogspot.com/2011/03/autodesk-revit-architecture-2012.html

·      Revit Server

·      Citrix support

·      Linked model improvements – Tagging rooms and keynotes

·      Autodesk Vault collaboration

·      Point Cloud support

·      Materials format underlying change

o   This was confusing and required two more years of enhancements to fix

·      Wiki-help file - this was an improvement on v2011, but still no graphics

·      Modelling enhancements including:

o   Adaptive components available in project environment

§  Not very compatible with the rest of Revit – refer:

§  https://revitcat.blogspot.com/2014/04/a-dozen-reasons-not-to-use-adaptive.html

§  Not available for structural or MEP categories

o   Solid-solid cut tool in families

o   Face-based void families can cut host families in project (limited categories)

No major enhancements in this version - tidy up after stairs and materials changes.

Reference: http://autodesk-revit.blogspot.com/2013/03/whats-new-in-revit-2014.html

·      Stair tools – minor fixes.  (Should have addressed significant shortcomings of new v2013 tools, but did not)

o   Landing shape-handle behaviour modified

o   Precast stair runs join floors

o   Additional location lines by Supports

o   Snaps improved, and some temporary dimensions added

o   Extra riser line on landings no longer displayed

·      Railing tools – Nothing!  There should have been a major follow up after new stair tools.

·      Displaced Views – shiny new toy!  Gimmicky marketing tool of limited use, albeit well executed.

·      Materials UI debacle of 2013 fixed up (although underlying structure is still confusing)

·      View templates – temporary view template override

·      Point Cloud improvements

·      Options to control Double-click to edit functionality

·      Non-rectangular viewports

o   Additional schedule categories enabled (architectural columns, detail items, entourage, generic models, grids, levels, pads, roof soffits, structural beam systems, structural area reinforcement, structural path reinforcement and structural fabric area)

o   Schedule Phase created or demolished

o   Text Styles to control formatting of schedules

o   Cell text overrides

·      Minor enhancements:

o   Explode imported solids in a family, allowing limited manipulation of elements

o   Conceptual massing – Align tool works on U/V angle on surfaces

o   Project Browser & Properties palette dockable in same window as tabs – really only useful on a laptop where screen real-estate is extremely limited.

o   Room calculation point

o   Selection locks – allow/prevent selection of Links, Underlays, pinned elements, by face (NB. The default for “Drag elements on selection” is still “Allow” – Autodesk stubbornly refuse to change this dangerous setting!)

o   View regeneration suspended during view navigation option – to speed up working in Revit

o   Bring to Front / Send to Back – for 2D items

o   Dual units in dimensions

·      Import / export enhancements

V2015

This was a very “lean” release, particularly for architects

http://revitcat.blogspot.com/2014/04/new-in-revit-2015-schedules-parameters.html

·      Sketchy Views – Shiny new toy, created because competitor software can do this (better).  It more or less works, but is a flawed solution that needs improvement (never happened).
Refer:
http://revitcat.blogspot.com/2014/04/new-sketchy-lines-in-revit-2015.html

·      Stair & Railing tools – Nothing!  Still no follow up to new stair tools.

·      Performance Enhancements

o   Faster view redraw

o   Faster selection graphics

o   Warning when multiple pinned elements selected

o   Attached Detail Groups behave as ‘Clipped’ instead of ‘Pinned’

·      Revisions:

o   Revision clouds by drawing tools (lines, rectangles etc)

o   Can delete revisions

·      Family Parameters sort order

o   Tooltips for family parameters

·      Schedules

o   Walls heights (NB. Warning: wrong values if wall is 'attached' - never fixed)

o   Images in schedules

·      A handful of small enhancements – some useful and some badly executed:

o   Anti-aliasing (smooth lines) by view or by project

o   Duplicate view automatically adds “Copy” suffix to name

o   Allow to change view reference after ‘Reference Other View’

o   Trim/Extend multiple elements

o   Tag leader behaviour consistent with Text leaders

o   View Titles allow more parameters

o   Manage Links Dialog has ‘Add Link’ button

o   Can display all hidden lines in a 3D view (by category instead of by discipline)

o   Ray trace interactive rendering view improved

·      Help files changed yet again!

  • "Site Designer" add-in released as a Revit extension (purchased by Autodesk from EaglePoint) - unfortunately this add-in was not intuitive and most people could not get it to even function, so it was effectively useless.  It never lived up to expectations, nor was it updated or modified by Autodesk at all.
 

V2015 R2

From mid-2016, Autodesk started releasing enhancements as part of point releases during the year – these were often things that were under development for the following year but did not require a database change, so they were released early for those on subscription.  For the sake of compiling a year-by-year list, anything from 2015 R2 is listed as part of 2016; 2016 R2 is listed as part of 2017 etc

V2016 (and 2015 R2)

References:  http://revitcat.blogspot.com/2015/04/whats-new-in-revit-2016.html

This version did not have any major enhancements – although it was noticeably faster than previous versions;  and had a reasonable list of minor enhancements, only a couple of which were specifically for architects.

·      Reveal Constraints - extremely useful tool that came out of 'Global Parameter' development

·      Performance Enhancements

o   Faster regeneration after toposurface editing

o   Multiple Processors for GPU

o   Synch with Central speed improvements

o   Faster updates to views that contain multiple instances of families

o   Improved performance where Revit link instances are loaded but not visible in the view.

o   Allow navigation during redraw option

·      Minor Revision enhancements:

o   Select & delete multiple rows at once

o   Change starting number for a numeric sequence

o   Alphabetic is now Alphanumeric

o   Add a prefix or suffix to values

·      Minor enhancements:

o   “ Remove Repeater” tool for dissolving a repeater (Array in Conceptual Modeling)

o   Search capability in Type Selector

o   New option to ‘Load a family into project & Close Family’

o   File upgrade version notification message

o   Properties Palette remembers last scroll location

o   New Pin/Unpin icons for hosted elements (curtain wall panels, mullions etc)

o   Import/Link position default changed to ‘Auto – Origin to Origin’;  Revit remembers previous settings

http://revitcat.blogspot.com/2017/08/index-for-global-parameters-in-revit.html

·      Global Parameters – showed great initial promise but sadly did not turn into the game-changer we had hoped – largely due to its limitations, which have not been addressed yet: 

o   each global parameter had to be individually enabled, and some vital ones are still missing: 

§  Array numbers not enabled;

§  Floor ‘Offset from Level’ not enabled;

·      Text

o   Can enter unnumbered or non-bulleted text in lists

o   Multilevel lists

o   Text Size parameter changed to accurately represent capital letter height  - NB. Most users won’t notice an improvement but will notice that text strings are wider when projects are upgraded, requiring a detailed checking process.

o   When rotating Project North a new option allows you to specify whether text notes should rotate with the model or maintain their current orientation in the view

o   Can specify text editor to display an opaque background and a border when editing

o   Text notes directly in canvas

o   New text editing tools in ribbon

o   All text is visible while editing

o   Text wraps, scales, and scrolls as you expect

o   Improved export text fidelity.

·      Schedules

o   Combine Parameters – only works in the schedule – cannot be tagged

o   Calculations in tags – has to match similar calc in the schedule – result is not a property

o   View templates for schedules and assembly views

o   Schedule Properties dialog improved

o   Can now display minimum values, maximum values

·      Performance

2018 (and 2017.1)

This version was even more ‘lean’ than 2015 !!

http://revitcat.blogspot.com/2016/10/20171-import-3d-shapes-swings-and.html

·      Import 3D Shapes (Rhino & SAT) – underlying import engine totally different (2017.1)

o   Only allows import (not link);  not consistent import UI; many import options missing; many Rhino shapes fail to import – needs more work.

o   Cut edges of shapes can be dimensioned

·      Underlay Navisworks files

·      Tag imported objects:  IFC; 3D Shapes; some imports from 3rd party add-ins

·      Export material and hatch pattern colours to DWG/DXF (2017.2)

·      High resolution (4K) monitor support (2017.1)

·      Repair Central Model tool (2017.1)

·      Model in perspective views – add, move, copy, rotate, align (2017.1)

·      Stairs:

o   Tooltips added (2017.1)

o   Old stair Sketch Tool removed – finally!

o   New Multi-storey stair tool – Good start but not without problems (needs more work)

·      Railings:

o   Top Rail and Handrail type properties UI tweak (2017.1)

o   Railings host on Topography – great news for doing fences.

o   Control of start and end points of railings

o   Overlapping railings on Multistorey stairs work better – still needs more work to fix this.

·      Schedules:

o   Schedule Links and Groups as categories - the best new feature in this version

o   Links and Groups have new system & user defined properties

·      UI Ribbon de-clutter – to make it look more modern, but actually not consistent, and harder to read!

o   Parameter tooltips added to some elements

·      Text

o   Quick input of special characters

o   Rich text format in labels

o   Tag text height updated to match Text elements – Tags may get wider during upgrade, requiring checking; still not included: Dimensions, colour legends.

2019 (and 2018.1 & 2018.2)

Another very short list of enhancements.  This version had two new features that should have been considered major – but both fall short of expectations;  neither has been addressed since.

·      Minor point release enhancements (2018.1,2,3):

o   Browser organization for schedules (2018.1)

o   Dynamo Player supports input for scripts (2018.1)

o   Scope boxes sort alphanumerically (2018.3)

o   Expand/collapse the Project Browser with right-click commands (2018.2)

o   Streamlined family loading – remembers last folder (2018.2)

o   Remember column widths in the Family Editor (2018.2) – nice but the ‘Lock’ checkbox column width still plays havoc (needs more work).

o   Fill Patterns dialog reorganised (2018.2)

o   Section box shape controls improved (2018.2)

o   Sketch of a railing that has been re-hosted to an element will be displayed on the level of the host when editing. (2018.1)

·      Tabbed Views – great idea but needs serious work to improve it: needs a way to manage/separate multiple project & family tabs (eg. Colour coding).  Until such basic functionality is fixed this cannot count as a major enhancement

·      Secondary monitor support – a good start but view arrangements are lost if Revit is minimised/maximised.  Until such basic functionality is fixed this cannot count as a major enhancement

·      View Filters ‘OR’ conditions enabled – very useful functionality, but not applied to schedules yet

·    Double-fill patterns

Minor Enhancements:

·      Levels in 3D – a most unwelcome enhancement that appears in all 3D views by default!  Ok – a few people want this but it should not have been a default setting.

·    Uncropped perspective views

·   Scope box improvements

·   New library of physically-based appearance assets

·      Split tool on railing elements outside of the sketch mode

·      Dimensions for cut curved elements

·      New warning when deleting levels

·      Slow double-click to rename views in Project Browser – another unwelcome irritation

Minor enhancements – point releases (2019.1 & 2)

·      New Home Page – clicking on a file opens a local copy by default

·      Site collaboration with Civil 3D (2019.1) – not considered useful for architects because they need simple site manipulation tools within Revit, not links to an unwieldy external program.

·      Move Pattern to top of wall (2019.1)

·      Import Double Fill Patterns (2019.1)

·      Perspective View enhancements (2019.1)

o   Duplicate perspective view keeps view attributes

o   Locked perspective views cannot change view attributes

o   Zoom in region moves camera, not zoom on uncropped region

o   Reset crop region enables crop visibility

o   Keyboard modifiers improved

o   Navigation in uncropped views faster

·      Section views – snapping and align tool works on section lines in plan (2019.1)

·      ‘Go to View’ and ‘Add view to sheet’ dialogs resizeable (2019.1)

o   Cannot handle changes of level in buildings (split level or stairs)

o   Cannot be adjusted after placement

·      Elliptical Walls and Curtain Walls

 

Core Revit Features:

·      PDF Import as underlay – good but does not support linked PDFs

·      Path of Travel enhancements

o   Adjust end/start points (2020.1)

o   Reveal Obstacles (2020.1)

o   To and From schedule properties (2020.1)

o   Waypoints (2020.2) – this finally made the tool useful

·      Schedules

o   Striped alternate rows (2020.1)

o   Freeze Header in schedules (2020.2)

o   Active row highlighted in blue (2020.2)

·      Support for Link/Import Sketchup 2019 format (2020.1)

·      Improved keyboard View and Fly-through navigation in Perspective mode (2020.2)

 Architectural Enhancements:

·      Generative Design in Revit – since this is not available to mere Revit users I can’t comment on its value to architects (it is not available to those still on Maintenance or those who do not have AEC Collections).

 ·      Slanted Walls –

o   This only includes sloping walls with parallel sides, not tapered walls, thus it is not particularly useful yet.

o   There are still a number of unresolved issues with joins in plan and angle controls.

·      Rotate Text in tags and section heads

·      Performance improvements

·      Design Options sorted alphabetically

·      Cuts Geometry parameter for voids in families



No doubt I have missed something from this compiled list - it is remarkably difficult to verify exactly what was released when.  However, it should be close enough to give us a good history of the changes to Revit Architecture over the last decade.  Of course this list does not include all those other streams of parallel development:  other disciplines and related software (MEP, Structure, Dynamo, API, BIM360 etc).
