Is there any way to mirror parts of a 3D sketch about a plane? I've built a weldment spaceframe and I need to export all the tube centerlines as a 3D sketch in *.igs format for our CNC tube bender/profiler. The problem is that I created the part by only making 1/2 of it as a 3D sketch and then mirroring the weldment BODIES over, but now I need a full 3D SKETCH of all the centerlines. I either need to mirror my original 1/2 3D sketch over or export only the tube centerlines somehow? They're all circular tube profiles so hopefully that helps. Thanks in advance!
