Hello, my problem is as follows.
I would like to send 2D shapes that have arcs for rounded corners to a CNC router for cutting. For simplicity imagine im using a single object whose shape is a square with 4 arcs making up the rounded corners.
If i draw the rounded square in SU and make it into a group or component and then send it to a CAD/CAM software called Torchmate, then after applying a male toolpath i wind up with 8 different toolpaths - 4 for the edges and 4 for the corners, rather than a single and and correct toolpath.
If i go back to SU and use the weld extension then i get a single polyline (welded lines and arcs) and a single toolpath in Torchmate but i lose the real arcs as they become these array of edges that are strangely still registered as arcs in SU.
If i use the bezier spline extension i wind up unable to create polylines with the specific shapes i am seeking. It seems that none of the arcs in bezier spline match the basic 2 point arc in SU.
So my question is this: is it possible to create polylines in sketchup while retaining real arcs, or do i have to delve into Autocad or some other program?
