Add Reference Geometry

Reference Geometry is a copy of a sketch-element, and its motion, from a different Mechanism-Editor into the active Mechanism-Editor.

Terminology:

Source Sketch-Element :	A sketch-element, in a moving or stationary Part in a different Mechanism-Editor.
Reference Sketch-Element :	A copy of the Source sketch-element to a Part in the active Mechanism-Editor.

Preparation example:

Two(2) Mechanism-Editors

•Source

•Reference - this is the active editor

A Circle in Source sketch-element

The Circle is in the Source Mechanism-Editor.

To see the Source Mechanism-Editor when the Reference Mechanism-Editor is active.

AND

•Right-click Mechanism name-tab of the Source mechanism-Editor and select Show with 'other Kinematic and Sketch elements'.

AND

•View toolbar > Spin or use your arrow keys on your keyboard to spin the model to see the two editor.

STEP 1:Start the Add Reference-Geometry command

1.Add menu > Mechanism menu > Add Reference Geometry

- or -

1.Kinematic elements toolbar > Add Reference Geometry

The Command-Manager indicates you must select two(2) elements

STEP 2:Select the two elements in the graphic-area

2.Click a sketch-element in the Source Reference-Editor.

Click the Circle in the Source Mechanism-Editor.

3.Click a Part in the Reference Mechanism-Editor

In this case there is only one Part - the Base-Part - in the Reference Mechanism-Editor.

STEP 3:Complete the Command

4.Command-Manager: Click in the Command-Manager.

Result :

The Reference Geometry is now in the Reference Mechanism-Editor.

The motion-values of the Source Geometry are also transferred to the Reference Mechanism-Editor.
