Surfcam Velocity III Surfcam Velocity III Gordieburns (Electrical) (OP) 7 Dec 12 14:01 I have a problem. Does anyone know how to take a flat DXF and have it projected on a radius drawing. I need to make a 6.813 radius drawing out of a flat dxf and can't figure out how to get it there. RE: Surfcam Velocity III moldcore (Mechanical) 8 Dec 12 18:17 What’s a radius drawing? Do you want to project a 2D DXF onto a curve Surface? Import your DXF then create the radius surface under it, then use Create>Spline> Project. If you want to machine onto a curved surface you’ll have to do the 2D path first, then in use 3D to project that program onto the surface.
