Intersecting a cylinder with a curves surface
-
hello all- I am trying to intersect this cylinder with the curved surface of the model such that they maintain a manifold mesh. the idea is to delete that reverse face protrusion and end up with a hole through the model. whats a good way to to do this? I have tried 'intersect with model' etc. any way other than fredo plugin? surely this can be done natively!
thank you for your help
all the best,

Intersect Faces will work but you'd make it a whole lot easier for yourself if you didn't have such ridiculously high segment counts on the curves.
Due to the incredibly tiny faces, you'll need to scale the model up quite large before doing the intersect routine.

Here's a revised version with more reasonable segment counts.

I just redrew it from scratch next to yours. I used your version for dimensions and then deleted it after mine was finished.
As for what is reasonable, that depends upon the application. If this is to be used in a model of a bed to show how the rails are attached to the posts, mine is overkill, too. If you are making a dimensioned drawing so a machinist can make them, it is probably about right. Even for 3D printing mine will probably be more than adequate. You could figure the resolution (diameter) of the nozzle for for printer and make the segment length at least that long but longer won't be a problem.
Your version of the "hole" has 512 sides. That's less than 1° between vertices. Even 360 sides would be too many for nearly every application. I used 96 sides and I think it is round enough to get the point across.
