Hello Oz.
Thank you for your reply. I think I have it figured out, but I’ll answer your question first…
I am doing the offsetting in Draftsight. I draw a spline in Draftsight. Those get the anomalies when importing into Lightburn. But what really gets the anomalies are new splines that have been offset from the original spline - also originally drawn in Draftsight.
Okay, how I think I fixed it is, I increased the CURVE TOLERANCE in the Settings menu. I had it set at 0.050 I believe. When I bumped it up to about 0.200 these anomalies disappeared. I wonder what are typical values in the rest of the options in the Settings menu. I think I have them pretty messed up, but I fixed this problem…
Thanks.
Tim
