What this tells me is you are using the 3d printing template that has the useless dynamic component for multiple printer spaces. Delete and purge it. Window/Model info/Statistics/ Purge unused.
This also tells me you are probably working at a very small scale, which can cause faces to fail to form.
And mostly I see different contexts, the orange cylinder has a bounding box so if the white is raw geometry you need to select it and choose Intersect faces with model, then remove the orange cylinder and delete the parts of the white that you don’t need.
Once you Purge your model you may be able to attach it.
Thanks, that worked, apart from when I do the intersect, some of the faces disappear on the white piece, and I need to somehow close the “cut-faces” where the orange cylinder walls penetrated the object. This should be a solid, filled object.
Might you know how to repair this?
Might have to do some more interacting to be able to upload the file.
I don’t see any blue faces on the outside of the component. What you’re seeing here is the inside of the component after the piece is cut out. I’ll try scaling it up, and redoing the work. thanks for the tip.
That’s also what I meant about context, if you have the orange cylinder actually touching the white part when you intersect them you will keep the faces. Not the tiny faces, that’s a different issue.
If you can upload your model it would helps us to show you exactly.
Thanks guys. I’ve also noticed that I “followed” round a 24 face circle, so the part is heavily tesselated. I think I’m going to start again and follow round a higher res circle. Have also scaled it up 100x, so will see where that takes us.
Is there an easy way to get back to the X-section, so I can re-follow-the new circle??
72 or maybe 96. In any case, I prefer to keep the number of sides divisible by 12 which means it’s also divisible by 2, 3, and 4.
I did this as a quick example using 96 sides for the overall part and 48 for the cylinder for the hole. Obviously the dimensions are right but it should give you an idea of how it could look. For 3D printing you might need to do something about the sharp edges where the pin hole breaks through.
