Trace

You can Trace the movement of one or a group of drawing objects.  You can create string art drawings and see how an envelope curve is formed.  Here are the steps:

1. Select   the drawing objects to be traced.
2. Click the Trace tool    and the Edit Trace dialog pops up.
3. You need a parameter to drive the motion of the trace.  Click the arrow key to the right of the Parametric Variable window to select from a list of all variables in the drawing. (If you entered the needed constraint in real terms, Cancel the trace and change your constraint to a variable by double-clicking it in the drawing window.)

4.  Simply fill in the values for the appropriate variable and click the OK button.

 

 

To adjust the range or number of traces, double-click one of the traces to edit the dialog.
