External Components
Objects that are outside of the DesignSpark Mechanical document file are external components. Designs that you load using the File tool on the Design tab are external. See Inserting another design.
You can make a copy of an external component internal. The copy will be included in the .rsdoc file so it can be viewed and modified in your design. The original external component will not be changed. See the instructions below.
If you have the Use lightweight assemblies option selected in the File import and export options, external components will be loaded as lightweight components. See Lightweight components.
