It seems that I missed something - Dan Stine (author of several Revit text books) has pointed out that the Treads/Risers subcategory does actually have an effect in plan views:
It controls the materials and surface patterns of the treads. I did some testing to understand the subtleties of how this works. . . . .
Here I am using my subcategory visibility colour overrides to make it easier to see what is being controlled by which subcategory.
- If your monolithic stair run does not have a separate tread
- If the stair run does have a tread, but the tread material does not have any surface pattern
|Tread material - Run type property|
|Material properties of stair run tread|
However, if the material of the tread is changed so that it has a surface pattern, this will display in a plan view
It looks different depending on the visual style of the view:
|Hidden Line View with tiles on treads|
|Shaded View with tiles on treads|
|Realistic View with tiles on treads|
|Hidden Line - concrete surface pattern|
|Shaded View - concrete surface pattern|
|Realistic View - monolithic concrete stair|
Really Weird Stair StuffIn order to hide the surface pattern of the underlying monolithic material in a plan view, you have to turn off both 'Nosing Line' & 'Riser Lines' subcategories. Turn off just one or other of them and you hide the lines, but not the material surface pattern. That makes no sense to me.
|Plan subcategories for materials|
How do you hide the material of the underlying monolithic structure?
- Make sure the material does not have a surface pattern, and view it in Hidden Line or Shaded View. Or:
- Turn off the 'Nosing Line' and 'Riser Lines' subcategories. That could be frustrating if you need to see the nosing or riser lines themselves!
Or (the better solution):
- Go to the Surface Pattern override for the whole stair; untick the Pattern Overrides 'Visible' checkbox (won't work in a realistic view)
The Pattern will then list as 'Hidden'
Which one of the three solutions you choose depends on exactly the result you are after, and on what Visual Style setting you have for the view.
For a Realistic View, you can hide the tread material (by Tread/Riser subcategory) but cannot hide the underlying monolithic material at all.
Material Linestyle OverridesUnlike the actual linework of the stairs, the lines within the surface patterns cannot have their weight or linestyle overridden in the Visibility Graphics dialog - they follow the standard rules for hatching lines. The colour can be overridden, but you have to change the overall stair category pattern colour override, not the subcategory line colour override. This means that the button to click on for colour override is quite different to the location of the 'Treads/Risers' subcategory visibility control checkbox(es).
The actual hatching pattern can be overridden from the same dialog - this allows you to choose a totally different pattern just for that view. If you set it to "No Pattern", it just clears the override, rather than temporarily removing the pattern as an override - which is frustrating if that was the result that you wanted, particularly if you just tried to override one element, not all in that view.
The line weight of the surface patterns cannot be overridden by view, but that is another story . . . .
