Problem wth extrusion of two curbs

#1

Hi!

I’m drawing an organic structure.
This is complex.
Now, with the curbs number , i have a big problem i hadn’t with the others: when i extrude, it’s like a ribbon for the external curb, and only the interior curb is an extrusion full. I tried the function “cap planar holes” it it’s written it’s impossible…
Sorry, my commercial software is in french but i try two explain each step with photos…
Thanks so much if you can help me…
First picture: only the inerior curb is an extrusion

When i try to extrude, i have this message "certaines courbes sélectionnées se replient sur elles mêmes. You can have unexpected results. Do you want to extrude?"

Hi FabLab - please post the curves in a 3dm file, I’ll take a look.

Hi Fablab - both of the curves are open curves (SelOpenCrv) so capping cannot work. Use CrvEnd and CrvStart in V5 (ShowEnds in v6/WIP) to locate the parts to clean up.

Hi Pascal, thanks so much! The only thing is that i have the french version Rhino, and i don’t know where it is on the tool bar? If you could show me where it is on the english toolbar of rhino version 5, i think i can be able to find it on the french version, because the logo picture is the same, but i don’t know where it is! :slight_smile:
Thanks so much!
