Locate Datums Methods
Select references from the assembly using one of the following methods:
• Click Three planes and OK, and select three orthogonal datum planes from the assembly to which the default datum planes of the newly created component will be assembled.
• Click Axis normal to plane and OK, and select a single datum plane and an axis that is normal to it. The system then creates a new component with a datum plane and an axis which it uses to place the new component with respect to the rest of the assembly.
• Click Align csys to csys and OK, and select a coordinate system in the top-level assembly. The system then creates a new component with a default coordinate system and default datum planes which it uses to place the new component relative to the rest of the assembly.
