When you generate a 3D trace curve, the software saves a series of hidden datum points and puts them in a group with the trace curve and datum planes. The trace curve group is saved as a feature of the paper part.

You can access this group in the Model Tree to delete or modify the coordinates of the datum points. Select the feature that contains the points, right-click and choose Edit Definition from the shortcut menu. Use the dialog box that opens to edit the trace curve.

For more information on layers and redefining features, search the Help Center.
