I have imported a curve from xyz coordinates. There is a small open section of the curve that I wish to "fill" with a tangent arc. However, I can not select the end points of the curve in order to close the curve. Also, the curve will not turn black.
Attached are screen shots. The first image is the full sketch that was imported by using a file of XYZ coordinates. The second image is of the close up section of the end of the sketch that is open.
Thank You
Tom
