Tip: Assembly Constraints in Creo Parametric

Regular Member

Are you interested in what Assembly constraints do and how they act when building an assembly in Creo Parametric? In PTC’s Creo Parametric Assembly Essentials course, you will learn about various constraints and how to apply them. Let’s look at some basic assembly constraints.


Assembly constraints determine how a part is located within an assembly, and they specify the relative position of a pair of references. Let’s look at three types of constraints: Default, Coincident, and Distance.

The Default constraint aligns the internal system-created coordinate systems of the component and the assembly. It is a standard practice to assemble the initial assembly component using a Default constraint.

The Coincident constraint enables you to insert one cylindrical or conical surface into another cylindrical or conical surface, making the corresponding axes coaxial. It also enables you to position two specified planer surfaces or datum planes to lie in the same plane.

The Distance constraint enables you to specify an offset value between selected geometry types.
