xNURBS: can't find good G1 result

i am just starting to use xnurbs and trying to find joinable (!) G1 surfaces.
i have been trying tons of different slider settings without any sufficient result. am I missing something?
any help appreciated, thanks in advance

I don’t see that here. Since your boundary surfaces are G2 continuous, you can even reach G2 on the XNurbs too.

edit: I see your doc tolerance is very tight (0.00001), any reason for that?

thanks a lot for the hint concerning tolerances, i wasnt aware of this. could this possibly have happened when changing units from cm to mm?

what is the tool you use to display the distances shown in the background of your screenshot?

no, maybe you imported a file that had these settings? I sometimes see it when importing step files.

It’s a plugin I wrote, you can find it on PackageManager (GlobalEdgeContinuity)

i did a lot of step imports on this project, maybe thats the reason.
i´ll check globalEdgeContinuity, the discription sounds interesting, thanks!
