Use the following general rules for placing mate references:
-
Add two mate references to a route fitting:
-
Add the first mate reference as a single edge mate to use with SmartMates when the mating component does not have a common mate reference.
SmartMates only use the first mate reference, so make sure that the single edge mate you create is listed first.
- Add the other mate reference for mating the fitting to components with mate references of the same name and type.
Use specific mate types - coincident and concentric, rather than default mates.
- Add mate references to ports on equipment parts, adding one mate reference per port.
- If a piece of equipment has several ports, add mate references to all ports, or to none. SmartMates are used for part placement if there are no mate references on any of the ports.
- Add mate references to components used at the start and end of a route. Typically these are flanges or electrical connectors, but can also be valves or elbows.
- Add matching mate references to electrical connectors and their mating socket components.
