Wall missing after Trim Elements To Roof/Shell

I have a wall under a stair and used the "Trim Elements To Roof/Shell" in combination with a "roof" to let the wall follow the slope of the stair.

 

But now, some of the wall is missing on 3D & on Section, but it is still showing on plan.

I've highlighted the walls & roof in green, and show in yellow where the wall portion is missing in section & 3D but still show in plan.

 

Am I doing something wrong?

Try using Solid Elements Operation ,which may be better for your required end product. Even you don't have to draw any extra roof for that as same staircase bottom profile will work very well. Do try and let me know.

You are not doing anything wrong - it has to do with how trim to roof works.

 

Trim to roof will constrain the 3D geometry of the wall to the projected area of the roof which in your case stops at the the connection roof-slab. However, the wall will still be shown in its full length in floor plan.

 

As Rajesh points out. A SEO using subtraction with upward extension is probably a better method here than using trim to roof.

You can show the projected area (or Trimming Body) under the roof in 3D by turning on the 'Trimming Bodies' option in your 'On-Screen Display' options.

They won't print if you leave them on.
