This section describes how you use the Assembly module's Constraint menu to apply positioning constraints to part and model instances in the assembly.
Using the Constraint menu Constraining two instances with parallel planar faces Constraining two instances with parallel planar faces separated by a specified distance Constraining two instances with parallel edges Constraining two instances with parallel edges separated by a specified distance Constraining two instances with coaxial faces Constraining two instances with coincident points Constraining two instances with parallel coordinate systems
