Applies a parallel relationship between two parts in an assembly.

You can apply a parallel relationship between two cylindrical axes, a cylindrical axis and a linear element, or two linear elements. For example, you can apply a parallel relationship between a cylindrical axis on a part you are positioning (A) and a cylindrical axis on a part already in the assembly (B).

A parallel relationship can be useful when you are creating a top-down design of a mechanism where a known radial distance must be maintained, but the final position of the part has not been determined. For example, you can locate the part at the proper parallel offset distance with a parallel relationship (A). You can then use another relationship, such as a planar align relationship (B), to finish positioning the part.

When the final location of the part is determined, you can finish the design process for the adjacent parts.

You can also apply a parallel relationship between a linear edge on the part you are positioning (A) and a linear edge on a part already in the assembly (B).

You can specify whether the parallel relationship is allowed to float or is fixed. When you set the Fixed Offset option, you can use the Offset Value box to specify an offset distance.

When you set the Floating Offset option, you can apply another relationship to control the offset distance. For example, you can apply a planar align relationship.
