[Closed] Build mesh Handler FAQ

Hi, I’m learning to create custom meshes with Max Script, and though i’m really finding the help reference very helpful, I still got some questions…
Basically, what I’m trying to do is to define a custom mesh object trough a series of parameters,
much like in the example Antistar in help…
And the concept is to define mesh A and mesh B and do subtraction.
But the problem is , that I dont know where to keep temporary meshes (or trimeshes) before i
finally subtract them and put them in mesh constructor.
Now, i figure the conversation should continue in code
This is what i made so far… keep in mind i’m new in coding and pretty much rusty in math ;D

Now , what I would like to know is how to put the current mesh that script creates , in temporary mesh, then create a new one , might be the same , just smaller , and subtract them and put in final mesh constructor… which would give in the end hollow Archcube
