With version 2.1.0 we have released the Draw workspace for ContourTrace. We are happy to announce a considerable improvement in the functionality of ContourTrace by simplifying the overall appearance by combining the Contour and Spline Operator to the new Drawing Operator. In this area the contours can be changed, duplicated, deleted, colored and much more. See the picture below.
