Drawing References

Question: If I have two identical parts and Part_1.sldprt isin a drawing with dimensions etc, and I want to stop referencingPart_1.sldprt in that drawing and instead reference Part_2.sldprt,(i.e. not lose the dimensions I have already placed), how can thisbe done?

I know I can use Solidoworks explorer to "replace" the part, butthe effect of this is that all assemblies etc referencing this partseem to be affected and all I want to affect is the drawing I amworking on.

Help please...SolidworksEdrawings
