I had mirrored (using Face) a surface along a plane and when i try to trim both of surfaces by one sketch i get nothing. Why is it so?
I think I might have an solution. What you got to do first is delete the mirror and than you can trim the surface with the sketch. And than you can mirror it.
I tried this and it works.
I tried to solve this problem and it's not working. Tried projecting the sketch on the surface and trimming it and it doesn't work. Tried extruding the sketch and trying to use the common trim and still nothing. If you find out how to solve this let me know.
The problem is that he used Mirror Faces.
I got a workaround by thickening the surfaces, thickened cut, then deleting out the thickened faces. It works though it's not very elegant.
I haven't figured out why SW doesn't "see" those surfaces
Well, technically it's not a surface, a surface has two faces.
Always use mirror bodies when mirroring surfaces, it'll change to mirror surface automatically afterwards.
That's a funny one, never caught it.. SW calls it a single face surface. If you knit two adjacent surfaces, you can face delete one, the remaining surface is once again "single face". I get the impression of either missing a face, or having one too many.
Your settings work, so... I'll continue remembering that single sided surfaces are bodies, and that surfaces with two faces are technically only two sided as long as they are four sided ( actually eight sided in this case) before becoming one sided after deleting one face.
It may be a good thing that I don't work so much with surfaces.
HaHa, well a single face is a single face. When you mirror bodies (misleading name, it's technically mirror surfaces) you mirror both 'faces' which make the whole surface.
Mirror faces has only few situations when it's applicable, never used it so far.
And don't use delete face for the same reason, use delete bodies.
