To add a Trace-Point of a Point relative to a Part (that is, NOT relative to the Base-Part), you should add a 2D-Cam.

To add the Point to a Part

1.Edit a Part to add a Circle to the Part, and Profile to the Circle

Do Add 2D-Cam

2.Select the centre-Point of the Circle (see 1)

3.Select the Part in which you want to show the Trace-Point

To show the Trace-Point

4.Edit the 2D-Cam (see 2D-Cam dialog-box) and show only the Pitch-Circle as the Trace-Point.

Special Condition

You can drag Points in the Mechanism-Editor if ALL of these conditions are met:


In the Part-Editor:

a.To add the Point, you do: Part-Editor > Add Point
The Point cannot be a start-Point, end-Point, or center-Point.


b.You do not add a dimension or a constraint to the Point

AND IF in the Mechanism-Editor:

c.You add a Trace-Point to the Point


To drag the Point more easily:

Reduce the Number-of-Steps to ~30 in the Machine Setting dialog-box

and / or

Drag the Point and then keep the mouse-pointer very still until the Trace-Point moves.
