I have 3D sketches that can create planar surfaces, what is the easiest way to create planar surfaces from complex 3D sketches?
Start the Planar Surface command, then right click in the graphics area and pick "Start Contour Selection". Then you should be able to pick one of the lines that forms the planar surface boundary and it will select the closed contour and make the planar surface.
The problem I'm running into is that after the first surface that method doesn't work for a second surface that is sharing an edge with the first surface.
I rarely work with surfaces, but I just played around with it a little bit. Apparently when you use the 3d sketch to create the surface with the method Jamil mentioned then the sketch is absorbed in the feature and the same line segment can't be re-used. You can start a second 3d sketch and convert entities from the first, then use this sketch to create the second surface. I know this is probably slower than you want, but it will get you there, and everything will be linked back to the original sketch, so changes to it should feed on down the tree to all surfaces.
As I said, I don't work with surfaces much, so someone may very well have a better way. It does seem like you should just be able to create a surface with any three line segments that form a triangle.
Interesting observation Glenn. I think it is not so much that the sketch is absorbed as the line segments within the sketch are absorbed and can't be reused. I discovered that if you draw each shared edge twice (a line on top of a line) in the 3D sketch then you can create the adjacent surfaces using that same method.
What about just using boundary surfaces. When you are making the surfaces you just pick two lines with the selection manager from the 3d sketch for each surface each time.
E.g. make two identical rectangles on the front plane with two sketches. Do one surface with one of them with planar surface and the other with the method I´m describing and compare them.
