Hi, I have a problem defining a mesh inside a build mesh constructor…
I want to define two custom meshes, with its own specified vertices and face arrays, like mesh1 and mesh2 , and then apply boolean operation with them, and put result in final mesh constructor, like
mesh = mesh1 - mesh2 .

But, i tried defining mesh1 like
mesh1 = mesh vertices:#([0,0,0],[width,0,0],[width,depth,0],[0,depth,0]) faces:#([3,2,1], [1,4,3])

and i get a message Type error: Call needs function or class, got: TriMesh <<

also i tried to create some instance convert it to mesh delete its faces and vertices and add new

like >

on buildMesh do
(
mesh1 = createInstance box
mesh1=mesh1.mesh
meshop.deleteFaces mesh1 #{1..mesh1.numfaces} delIsoVerts:true
setmesh mesh1 verts:#([0,0,0],[width,0,0],[width,depth,0],[0,depth,0]) faces:#([3,2,1], [1,4,3])
mesh += mesh1.mesh
)
but…
i get this error message in setmesh line of code..
>> MAXScript Scripted Plugin Handler Exception:—Unknown system exception

I really dont know what am i doing wrong or what i’m missing.. Please help

"setmesh mesh1” should be:

Something else is wrong after that: -- No “"+"” function for Mesh class

The scripted primitive wasn’t giving much feedback to the listener, so how I got that error was by putting the buildMesh interior in its own script.

I’ve not messed with much mesh()/trimesh() stuff before though, hope this helps get you in the right direction.
