I am trying to extrude a closed curve so that I can create a solid .stl. When I am extruding the curve it looks all jagged. When I open the .stl in Makerbot if is also jagged. ***This is not just a rendering issue for the mesh it actually exports jagged. Check out the attached screen shot. Notice the2nd from bottom left image with the red dot on it. You will see that around the edges there is a jagged shape escaping.
Why is my line not remaining the smooth curvature? How do I fix this?
