You can access and share assemblies using tool palettes, catalogs, or assembly drawings.
For example, you can create an assembly in your drawing, and then drag and drop it to a tool palette. Once it is in a tool palette, you can copy an assembly from a tool palette into a catalog. You can create a tool palette or a catalog that contains multiple assemblies, and then share that tool palette or catalog with others.
You can also save an assembly to a drawing file (.dwg), and then drag and drop that drawing file into your current drawing.
The following list summarizes ways you can share assemblies:
- copy an assembly from the drawing area to a tool palette
- copy an assembly from a tool palette to the drawing area
- copy an assembly from a tool palette to a catalog
- copy an assembly from a catalog to the drawing area
- copy an assembly from a catalog to a tool palette
- drag (copy) an assembly drawing (.dwg) into another drawing
