A Part-Outline is the symbol for a Part. You can change the size of symbols in the Edit menu > Application Settings | Accessibility tab > Graphs > Symbol Display Size.

You cannot edit a Part-Outline.

You select the Part-Outline to edit a Part.

E.g.

•Double-click a Part-Outline to edit the Part in the Part-Editor.

•The color of the Part-Outline helps you identify if the Part is or is not, kinematically-defined.

You can edit the colors of the Parts that are kinematically-defined and not kinematically-defined.

In the Application Settings, we use the terms for the colors of these elements:

•Part Solved for a Part that is kinematically-defined

•Part Not Solved for a Part that is not kinematically-defined

See Edit menu > Application-Settings > Graphic tab > Display Colors > Part Solved / Part Not Solved.

Blue Part-Outlines - or near to Blue.

The Part is NOT kinematically-defined.

Other names for Blue Parts are:

•Completely-Free - without a Joint

•Free - with a Joint, but not kinematically-defined

•Part Not Solved

Green Part-Outlines - or near to Green

The Part is kinematically-defined.

Other names for Green Parts are:

•kinematically-defined

•Part Solved

Note: The Base-Part is always a Part that is kinematically-defined, and therefore near to Green.

Multi-colored Part-Outlines

Each Part has a random color when, in the Forces Toolbar, you:

•Enable Calculate Forces

and

•Display Force-Vectors

The color of the Part-Outline is the same as the color of the Force-Vector that acts-on the Part.
