Solid Element Operations (Bounding Box)

[Anonymous]

I have a recessed in-wall trash receptacle and I'm trying to subtract the wall where the receptacle is.

Is there some easy way to do this?

I could make a niche behind it, to fake it, but is there some way I can extract the bounding box from the wall?

..or any other idea?

If your trash receptacle object has a solid box (PRISM) that is the size of bounding box, then a SEO will work.
But if your objects is not solid then it won't.

However if you want to edit the GDL, then it is possible to make it think there is a solid box, only when involved in a SEO.
Something like this - you will have to adjust the PRISM (or what ever form you want to use) to suit your object size and position.

!!GLOB_CONTEXT = 44 !!!!uncomment this line to test prism in 3D preview
!! use prism to cut when used in Solid Element Operation
if GLOB_CONTEXT > 40 and GLOB_CONTEXT < 50 then
MODEL SOLID

prism_ 5,zzyzx
0,0,15,
A,0,15,
A,B,15,
0,B,15,
0,0,-1

endif

Otherwise the additional niche is probably the best option.
