3DCS contains several types of part constraints to give users the ability to model a large range of assembly processes. The list of moves, however, can be confusing to a new user. This document divides move routines groups based on frequency of use and briefly defines the routines.

 

Frequently used Constraints

Fixed holds all of the parts in the Move Parts list in their current location and orientation. Any moves that list one of the parts as the "object" will force the "target" part to move instead.

Fix Together holds all of the parts in the Move Parts list perfectly rigid relative to one another. If one of the parts is moved then the other parts will move with it.

 

Intermittently used Constraints

Coincidence locates the features to be coplanar, coaxial or coincident.  

Contact locates the features so that their surfaces touch.

Offset locates the features to be parallel (if applicable) and separated by an offset value.

Angle locates the features to be rotated apart from one another so that the angle between then is the specified value.
