Hello everyone,

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!

Hi Corey,

You need to get rid of the red lines in my image below, then add one on the bottom edge of the model, where my blue arrow is:

The idea from that lesson is that there be a single closed contour.
