@Box Yes thank you, indeed I could have talked about this setting

merci

Merci très bien fait

Yes indeed it is another interesting solution than applying a texture, but the rendering is less pretty. The goal here is to make a screw very similar to reality, without drawing spirals. Everyone will choose their solution according to what they want as a result. There are others like achieving a revolution ... Thanks for the advice to those who read the comments.

Merci bien Pilou

Ou encore plus simple, je l'avais oublié celui-là! (THX Tenrev) PCon Planner gratuit! Recharge n'importe quoi et recrache du SKP à n'importe quelle version!

Ok thanks box

I added the chapters in the tutorial, this allows you to directly access the parts you want to see or review.

Thanks for your advice, HP support made me reinstall the printer, I installed the latest drivers, I updated the printer firmware, it didn't change anything. They say it's from sketchup, there's nothing they can do. The problem is the same on MAKE 2017 and on 2021 PRO. I don't know what to do anymore, we have a new printer that is useless!

A big thanks

From this particular tutorial beginner can learn how to squander precious time and in the end get geometrically wrong result (this is especially obvious when the bulge of the wall is more pronounced)
