About Adding Items to a Content Library (AutoCAD Mechanical Toolset)

You can use one of the following ways:

• By adding the current drawing to a custom content library.
• By adding selected geometry to a custom content library.
• By adding a block to the content library
• By creating an item from scratch.
• By copying an item from a standard part library

The first 4 methods enable you to create items that do not exist in the standard part content library. The last method lets you create an item that is a variation of an existing standard part or feature. For example, a steel shape with chamfered edges.

If the selection set you are adding as a new item contains parts or features inserted from a content library, they are ignored. However, if you explode them before hand, they are not ignored.

For example, consider a drawing of a plate with a hole, where the hole was inserted from the standard part library. If you add the plate to a custom content library, the hole is ignored. However if you explode the hole before you add the plate to the library, the hole is not ignored.
