When you use the Create Sub-Template command to make a stand-alone shape (such as for a curb) to insert into a corridor or any other template (such as a corridor side slope template), you can choose a Connect mode option. This setting lets you control the number of connection points with other instructions. This short video explains how the connections work.Credit: Scott Bridges

Can an existing sub-template be mirrored or does it do this automatically?
