So I'm trying to plow through with the Softimage/XSI mod-tool, and I feel like there's some sort of mental model which hasn't clicked. (1) Does anyone have advice for approaching these kinds of tools from the mindset in Hammer? Tutorials don't often deal with this as much as "Do W, X, Y, to get Z." When I first sat down with Hammer, it took a while, but eventually I got this whole "Brush" and "Entity" and "Two kinds of entities" and "this is when you vertex-edit and this is when you slice" stuff down. I'm going through a similar phase again, but with a far more complex and confusing interface. If I make a cube, I can't move the points to "vertex edit it" in the same way Hammer would let me: It seems like it wants to enforce that the object must have flat planes at all intermediate steps, so I can't drag vertices directly to where I want them to be... (2) Is there a way to get Hammer-like vertex-editing behavior? Should I use some other method instead of the cube/cylinder/cone/etc. primitives?
