3ds max 2010 extrude grouping

Talbot

Hey everyone

I'm having this odd extruding problem in max 2010. Basically what I'm trying to do is take a cube (that has an edge wrapping around the center), take the top half, and extrude them out. All of them connected still and still centered. None of the "extruding types" seem to do what I want. Local Poly is the closest thing but that sort of curves the edges.

Does anyone know what I'm doing wrong? I don't know why it is doing this. I think it may be some new thing in 2010 but I'm not sure. All I know is that I have never had this problem.

Shell modifier instead maybe?

Usually to do this kind of thing, I would extrude with an Extrusion Height of 0.0, then scale up the resulting polys.
I'm pretty sure Max has always done this with this kind of geometry.

Yeah thats a good idea. You could also flatten out each of the sides with the make planar xyz buttons.

I use Shell to fix this problem. I wish extrude had built in "straighten edge" checkbox.
