# C.2.58 Part Number for this Manufacturer already exists....

The Part definition you're attempting to create uses the same Manufacturer and Part Number as an existing definition. Saving the definition with the same Manufacturer and Part Number will cause XTrakCAD to update the existing definition. If the previous definition must be preserved, then choose a different Part Number for the new definition.

Refer to section 2.9.1.2 for detail.
