More, with V. 3.0, it is no very often that you need to get back to the drafting module, as a lot of 2D tools are now included in 3D module. I don't see anything that you canno't model from the beginning into the modeling module. Compared to Vellum, Z is a real 3D minded soft. I agree that FormZ is an outstanding 3D Modeler, which is why I use it. But as far as the drafting module, weaker than Vellum Solids.
Vellum has associative dimensioning, HUGE time saver.
What a drag. Vellum has a model to sheet command that allows a 3D model to have multiple views pasted automatically into a predetermined layout for adding dimensions and printing. Any help with using Z for mechanical production drawings would be appreciated. Sorry, I meant thorough, not through. It is still the best complement of software usage, even though my Vellum is now a four year old program.
