Hi, Jelle: post-parameterization, I mean a workflow that goes sort of like this:
(1) import STEP file from another CAD system. for some parts, it is simply easier to use a point-and-click system to build the model. A good example right now might be 3d lettering. (2) use this object as the target of subsequent modifications and additions. Examples might include adding other features, drilling holes, etc. CadQuery is particularly useful in this case, because a typical operation might be to import the STEP geometry, and then locate a new feature on a particular face-- without having to compute where exactly that face is. So, these essentially treat the original STEP as read-only. In the future, i would like post-parameterization to actually modify the underlying STEP geometry itself, but I have no idea how to do that. For example, is it possible to start with a cylinder represented in STEP, and then change the upper face diameter to a larger value, thus producing a truncated cone? I _think_ that's actually really hard-- so i'm not going to attempt that for a while. This capability is already quite good: OpenSCAD is my main competitor, and it only supports STL file import. This format is the scourge of the 3d earth, and I do not intend to support it. :) I'm definitely open to ideas on how to make this platform rock....
