Part :

A Part is a rigid-body. Its length is defined by the distance between its start-point and end-point.

There is a line between the points. The line is a CAD-Line.

A Part, free from joints, has three degrees-of-freedom - two translational and one rotational.

Base-Part :

The Base-Part is the fixed frame of reference of the Mechanism-Editor.

The Base-Part has zero degrees-of-freedom relative to the Mechanism-Editor.

Kinematic States of Parts:

Not kinematically-defined :

The state when the Part it has one or more degrees-of-freedom.

Other terms are a Free-Part, or a Part that is not solved.

kinematically-defined :

The state when the Part has zero degrees-of-freedom. It has a Mobility of Zero. The model must be kinematically-defined before you can analyze any kinematic (Motion) and kinetostatic (Force) data.

Another term is a Part that is solved.

Note: The color of the Part-Outline is different in the two kinematic states.

STEP 1.Start the Add Part command

STEP 2.To add the Part

The Part is now in the graphic-area.

Note:

Add Part is not a persistent command.

Do Step 1 and Step 2 again to add a new Part.

Did you know: You can hide Part-Outlines (Display Filters - Part-Outlines) to see only the CAD-Line and the Part's axes.

You can edit the Part if you double-click the Y-axis.
