i had the chance to use vectorworks and wasnt impressed with it. If i were going to go the parametric "building model" route, i would take archicad ovr any other package, Well, maybe revit (whcih was acquired by autodesk last spring). Revit just isnt made for mac/linux. Form-Z i hear is a well-rounded modeler, most users are ex-3dstudio viz users. Maya is more aimed at high-end animations/models, like video game development or movie effects and movies..i think it would be a waste of money to buy maya for cad/modeling.
Is blender a cad modeler, or is it a full-blown animation package like 3d studio max or maya??
