Alternate configurations within assemblies

Suppress or un-suppress mates according to the configuration - right click on a mate

Trevor,

     the part that moves will be in the assembly twice. One instance will be suppressed in each configuration.

See Attached.

Right-click the dimension and select "Configure Dimension". You never need two mates for the same thing, you just change the dimension of that mate per configuration.

Expand the Mates folder and click on the Distance Mate to show the dimension in the graphics area.  Right-click on it and choose "Configure Dimension" from the drop-down.  That will take you to a simple design table, with a row for each configuration and a column for the distance dimension.  Enter the desired value for each dimension.  With this table still open, you can go back to the tree, expand to another distance mate, and double-click on it.  That will add another column where you can suppress the mate for selected configurations, or in your case, click on the drop-down and select the dimension to add to the table.  Enter the desired value for each configuration again and repeat as needed.  You can delete the Suppress column if you don't need it.

You can also name this table, and then save it to add to or edit later.  If you just click on OK without saving your changes will be in effect, but if you want to make changes later you'll need to start a new table.

Trevor,

Alex is right - I missed the dimension comment in your question

You can configure your mates, RMB on the mate and select configure feature.
