Disturbed faces


I’ve subtracted 3 rounded solid shapes from a cylinder, only to find out the faces were ‘disrupted’. Is there any way to fix this, or should I try something entirely else? Maybe some plugin I can use?

Thanks in advance!

Most likely you just need to work at a larger scale. SketchUp is making very small adjustments in the locations of vertices to keep the faces.

I’ll give it a try, thanks for the quick reply.

edit: I’ve scaled up by a factor 10, problem still seems to exist. Should I scale up even more?

Yes. I would model with units set to meters and treat the dimensions as such. I did a quick eyeball model similar to yours. I made it shorter just to make it easier to see the geometry.

It’s modeled with a diameter of 20 meters and a wall thickness of 0.75m. This can be scaled down later to 20 inches or 20 mm easily enough. It could be scaled down even more but the wall thickness might be too thin.

Looks a lot better now, thanks!

Good deal.

FWIW, you might find it easier for things like this if you model centered on the origin. That way you have a good fixed reference point for the center of the model.

And for my quick version of your thing, I drew the “cutters” tapered. That might give you better geometry in your piece.

Looks like a good alternative, how’d you go about making the rounded edges?

I used FredoCorner to do it but it could have been done with Follow Me. The only important parts are the rounded edges where they pass through the cylinder.
