When you work with Mold or Cast models, best practice is to set the same absolute accuracy for the reference model, the workpiece (die block), and the mold or cast assembly to maintain a uniform computational accuracy of geometry calculations.

When you create the workpiece or die block in Mold or Cast mode, its accuracy is automatically the same as that of the assembly model. When you assemble a workpiece or die block, you should set its accuracy to that of the reference part and assembly model.
