I'm looking to fill with material between the underside of the helical slope and the lower plane (material represented in red thanks to my talents on paint), do you have a tip the community? I tried to fill in the material and then do a combined function but I didn't get the expected result.
I hadn't thought about it... I started a sweep with a propeller in the opposite direction and then a combine function, but it requires more function than with your proposal! Sometimes, we want to make it complicated when there are simpler things! Thank you Cyril
