Defines which inter-part link options you want to use.

Allow Inter-Part Links Using:

Specifies that you want to use inter-part links when set. You can then select which of the inter-part link options you want to use.

Inter-Part Copy Command	Associatively copies surface geometry from one part file to another part file when working within the context of the assembly. The geometry you copy is associative to the parent part.
Include Command in Part and Assembly Sketches	Uses the Include command to associatively copy edges from a part in the assembly into the current profile or sketch.
Sketch Relationships to Peer Edges	Applies geometric relationships and driving dimensions between elements in the current profile or sketch and the edges of another part in the assembly when the Peer Edge Locate option on the Tools tab is also set.
Assembly Reference Planes In Feature	Uses an assembly reference plane when constructing a new feature.
Assembly-Driven Part Features	Constructs assembly-driven part features in an assembly. Assembly-driven part features add an associative feature to each part they cut. When you update an assembly-driven part feature in the assembly, the individual parts are also updated.
Paste Link to Variable Table	Pastes an assembly variable into the variable table of other parts and assemblies; and to link values from a spreadsheet document, such as Excel, to a design variable. When you link variables from an assembly or a spreadsheet you can control dimensions in multiple part documents simultaneously.
