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.

New in Revit 2018.2 - Pattern Dialog Box


Following on from my last post about new features in Revit 2018.2, there are some very nice tweaks to the Pattern dialog boxes:

Fill Patterns

  • The Fill Pattern dialog box is now fully resizable (height & width) - Revit remembers the resize operation during the session.
  • The Fill Pattern dialog box has been redesigned to replace text icons with visual icons - as per many other Revit dialog boxes.

Old dialog box

  • No Pattern <None> is now at the top of the list (when accessed from a dialog box that has the option to remove a pattern, such as the Material dialog box) - this replaces the 'No Pattern' button at bottom left of the old dialog box.
  • Solid Fill is now second from the top of the list (Drafting patterns) after 'No Pattern' - generally I think this is a good thing.  NB. This is not the case with the Override dialog boxes, which have not yet been redesigned - so we have another new inconsistency.

  • There is now a Search/Filter function for patterns - it will filter the list to only include whatever contains the text you type into the 'Search' box.  It is not case sensitive.    Watch out for this feature:  if you have any text in the search/filter box, you may not see the <None> or Solid fill items at the top - it will take some getting used to, and will surely catch you out a few times.
  • It is now possible to select multiple fill patterns when the dialog box was accessed from the Manage toolbar (but not from dialogs that require you to choose a fill pattern to be used somewhere - like the material dialog box);  If multiple fill patterns are selected, they can be deleted but not edited (the edit icon is greyed out).

Edit Fill Patterns

The Edit Fill Pattern dialog box has been redesigned - the new overall layout is more logical:

  • 'Simple' patterns are now labelled as 'Basic' 

  • When listing custom patterns from a pattern file, it shows 4 instead of 3.  When the dialog box is resized vertically, it only increases the size of the preview, not the list of custom patterns, so you still need to use the tiny scroll bar on the right.
  • The 'Import' button (on the left) has been replaced by a 'Browse' button (on the right) - why?
  • The Import Scale value has been unlocked so it can be changed at any time after importing - this sounds great but BIM Managers may not be happy as they will lose the ability to set and lock down pattern scales.
  • Changing the scale without re-importing is immensely useful, as we often do not know where the pattern came from.  In this situation,  the preview updates as soon as you change the scale.
  • We have lost the File Units -  Aaaargh!  Why?  I like to know if the source was metric or imperial.
  • As with the old dialog box, we cannot see the name of the imported pattern file, which would be useful.
  • We now have a search/filter function for custom patterns, which operates much like the one on the Fill Pattern dialog box - this only works immediately after importing a pattern file. 
  • The title 'Settings' seems a bit odd when the pattern is set to custom - it was obviously designed for Basic/simple patterns, where it is more appropriate.

Overall, this is a welcome change to the UI, with only a few minor quibbles.  It would be great to have many, many more such minor improvements that incrementally take away the pain of using Revit.
