Ok im having troubles trying to extruding a tangent arc through a rectangular base. It keeps giving me a contour error which apparently means that they are not connected to each other correct? But im following off of the solidworks essential book 2012 step by step and somehow i end up with contours? Ill post some pictures of what im trying to do. The first picture is what im suppose to do. The second one is what I had done and what wont allow me to extrude. I hope that this is clear and maybe someone could possibly tell me how on earth these contours happened?
Thanks for your time!
