Here's a problem we've all had

Extruding - for example - a profile

A failing profile (gaps, overlaps and non-planar) - finding the problem - and fixing it - is often a pain in the ASS !

Please can we see more help / feedback / active support in correcting profiles for further processing

I suggest every failing profile should invoke a profile manager - which can report EXACTLY and GRAPHICALLY what™s wrong with the profile in question

I 3rd'nd that.

I have had a number if imported meshes that were seemingly great, yet after turnign to surfaces, and turnign on the points, I could see some faces angling in, yet it took much zooming to uncover other edges not coincident. This did tell me that my original pre-imported part had some geometry with too many tight intersections or facets, and reduction of them helped. But, still...

I've found I have much fewer problems if I invoke a work plane snap when drawing the profile.

I think there must be a whole load of checks that could be run on a profile

- look for points and very tiny lines with zero or effectively zero length (I seem to get from Illustrator imports sometimes - so small you cant see them)

- look for duplicate curves

- out of planar / tangent control is out of planar / tangent control has zero length

- mal-aligned tangents that will cause cusping and other problems down the road

- gaps - AND OFFER TO FILL with straight line, tangent continuity (G1) or curvature continuity (G2)

- offer a best guess - to fix it automagically and move on

more thoughts required
