This Revit feature really is obscure, and I can never remember how to do it without looking online for solutions. Plenty of people have posted on blogs and forums about this one, but I have my own slant on it. Most of the references to this are something like "How to create sectional perspectives in Revit" - and then describe how to apply a colour pattern to the cut surfaces of the section.
Applying Colour/Hatching to Cut Edges on a 3D View
In fact this technique applies to any 3d view, perspective or otherwise - but only if a section box is applied as a view property:
There are several subtle settings that control how and when this works:
- It only works when a view is set to Coarse Detail Level (not at medium or fine)
- By default, the Poche material has a dark blue shading colour and NO cut hatching pattern - you can change this of course.
- This means that the colour will only appear if the view is set to Shaded, and not appear if the view is set to Hidden Line
|Medium View, Hidden Line - No poche material is applied|
|Coarse View, Hidden Line - No cut Shading visible|
- Once the view is set to Shaded, the shading colour appears - this is standard Revit behaviour, but in the context of the other variables it can be confusing
|Coarse View, Shaded - Shading Colour is visible|
- You can also add a cut hatching pattern to the Poche material
|Coarse View, Shaded - Shading & Cut Pattern visible|
- If you have a cut pattern defined for the material, you can revert to a Hidden Line view and it will display the hatching but not the shading colour (again, this is standard revit behaviour)
|Coarse View, Hidden Line - Only Cut Pattern is visible|
- Alternatively you can use a solid fill colour for the cut pattern, and this will display on a hidden line view
|Coarse View, Hidden Line - Cut Pattern (solid colour) is visible|
- If the shading is set to zero transarency, it will show neither the shading colour, nor the solid fill colour - ie. the clash makes revit give up and show no poche.
- If you set the shading to semi trasparent, it shows the solid fill colour but at the shading transparency!!!
|Coarse View, Shaded - solid fill pattern, 50% shading transparency|
No wonder I can never remember this setting - it is so obscure and has so many variables to juggle in order to get it working. If you forget just one variable, it may not work at all.
- Any 3D view (perspective, Isometric etc)
- Section box must be active (although it can be hidden in Visibility Graphics)
- Section box must cut through the model (Poche material only applied to cut surfaces)
- Coarse Detail Level view
- Poche material
- Shaded View shows poche Shading colour (and cut pattern if it has one)
- Hidden Line View shows poche cut pattern only (nothing displays if no pattern is set)
- Shaded View + Solid Fill cut pattern + Shading colour = ??
