Trimming curved wall below stair

[Anonymous]

Attempted an SEO with a wall and stair in order to show curved wall below curved stair. Something I am doing is wrong. Does anybody have experience doing this?

Some stair objects are not "Solid" elements and therefore do not work with Solid Element Operations.
What stair object are you using.

It is a circular stair, see attachment, I want to cut the curved wall to the bottom of the stringer, or 6" above the top of the steps (haven't decided). Would this stair be a "solid" element? if not, how would I use the roof tool to cut exactly where I want?

To tell if the stair is a solid model cut it with the marquee and see if it looks hollow.

If you can't get the stair to cut the wall there is a ramp object in the library that should do the trick. Another approach would be to use a mesh and an intersection SEO with the wall. Trying to make roofs for this purpose would be an exercise in frustration.

There is a curved ramp in the AC library which will trim the wall using SEO.

Using the mesh tool is you preferred option in that case, 8 clicks and it's done. No need for SEOs.
- click the 4 corners of your "wall"
- arc the 2 longer sides of the resulting rectangle
- set the height of the 2 highest points of the "wall" and Bob's your uncle...
