Hi Hayden,
If I understand you correctly, you want to access the component interface command?
1) Config.pro option(hidden); enable_component_interfaces (yes)
2) Part mode; SET UP/COMP INTERFACE
3) Select the type of assembly constraints you want to have come up automatically with that part, face, axis etc.
You can have more than one "set" of assembly constraints for a single part.
Hope this helps
