Firstly let me say how pleased I am to be here. An active forum is a great place to find, especially when you are a newbie to a subject. I am quite familiar with the older "deluxe" versions of TurboCad but along with my version 15 Pro comes the big bowl of humility as I start to learn a new complex program.
Starting on 3D has been a frustrating challenge. As I reviewed some of the threads on this forum I recognized many of my mistakes in the posts of others, "Over exploding"parts, failing to close a profile correctly, not referring to the "selection info". I wish I was smart enough to make mistakes only once but that is not in my track-record!
A practical question if I can be so bold at this point. I am working on a project for a hand tool that basically looks like an electric drill. The 2D profile consists of a simply created mechanical working end for the tool but then I need to add an "ergonomic" handle which is designed using various curves. Predictably, this usually results in me getting a series of surfaces on extrusion instead of a 3D form. The handle design involves perhaps six independent curves that are supposed to meet end to end, it looks as though my problem is failure to connect the curves.
a. Should I, must I, join the independent curves into a polyline before extruding or should they extrude "as is"?
b. Is there any advantage from making the whole profile into a polyline?
c. Is there a way of detecting breaks in a polyline when joining or chaining? (I cannot detect the breaks visually even after zooming in.)
