I have parts that when i add them into an assembly I want them to automatically mate into the assembly.For example if I have an assembly with Part A, B & C and Part A has a descriptive Plane A and Part B has a descriptive Plane B and Part C has a descriptive Plane C. And i add Part D with descriptive Planes A, B &C. Is there a way for Part D to automatically mate with Parts A, B & C when I add Part D to the assembly instead of manually adding coincident mates.
