Replace Block Name (Library Menu)

This command replaces instances of particular blocks with other instances. This is done by altering the reference contained in the instance. The display parameters (position, rotation angle, scaling) and the local attributes of the instance remain unchanged.

The "Replace Block Name" dialog appears, in which you can specify which block is to replaced by which other block.

As only instances are affected by this command, the substitution can be undone using the Undo command
