I have created several skill procedures that draw cutom paths. The problem is that I don't see a preview while drawing the path, only a rubberbanding path with always has a with of 1.
Idealy, I would see a preview while adding points to the path (like in the Create Path and create Multipart path functions).
I hear you think, why don't you just make a multipart path template, but I want to use an options form to set different parrameters instead of having a huge list with template flavors.
You don't have quite as much control when using the public API (some things are only possible from the C level too). You should contact customer support to request the ability to do this with justification as to what is different about what you're trying to do from the built-in capability.
