New NX sketcher

[ryan-feeley]

Hi Jim Elias

What do you mean by “edge cases”, and what do you feel needed to be “better” as regards the old solver?

I was actually thinking about the sort of stuff that you’d commented on in my other post about the solidworks sketcher. You’d said

Splines in sketches in SWX have invariably proved unreliable (and often unpredictably unreliable).

It’s a typical issue to have a constraint or dimension that flags as overdefining or unsolvable, but when the “offending” item is deleted and recreated, everything is suddenly fine… until the next rebuild, then it’s rinse-and-repeat.

Building reference “steering helpers” as below will often reduce the agony, but usually doesn’t turn out to be a cure-all.

I don’t have a lot of experience with the old NX sketcher, and none with the new one. I’m curious if in your experience either of them has requires less of this sort of rinse-and-repeat hassle. In particular when working with splines.

Thanks for taking the time, and have a good one!
