I’m a previous user who is just getting used to the new (well, to me interface).
I have imported an assembly from a .obj file.
After relearning how to select and go to edit mode, etc. I can select one of the imported objects but am a bit confused as to do things.
First, the faces are tan, the vertices are orange, some edges are cyan, some dark tan.
It appears the cyan edge are surrounding two triangular faces and the dark tan edge is diagonal to the corners of the cyan rectangle.
I’m sure if I knew what I was looking at I’d have search terms, but, I a bit befuddled at this point trying to fit new workflow with my old, dimly remembered (maybe 5 years…) workflow.
My ultimate goal is to smooth out the sides of the screw.
Tan and orange are simply selection colors. If you deselect everything they’ll go away. The cyan highlighting is for edges marked as sharp. Do a Edge → Clear Sharp to make them not sharp.
Since it’s an import, to smooth things out you may also need to clear custom split normal data, shade faces smooth, and maybe enable autosmooth.
Is there a way to select only some of the marked sharpe edges?
Basically deselect some. When I tried that all the chamfers on the screw were rounded to point of looking like fillets.
I’ll do some search on custom split normal data, shade faces smooth, and autosmooth.
No. If selecting by using the sharp mark as criteria, you can only select all with such mark. There are other ways though. For one, there’s Select → Select Sharp Edges, where you can adjust the “sharpness” angle. Then there’s the possibility to actually convert your mesh to something with a better flow and use normal selection tools. E.g. try a Face → Tris To Quads, and you then may be able to select an edge ring around the nut in one ctrl+alt+click.
Also, sometimes selecting everything that you don’t want and inverting selection may be easier.
