What's the best way to make a chamfer at the assembly level without affecting the detail part level in CATIA V5?

Need to be able to do a machining operation at the assembly level, but can't seem to figure out how to make the feature be only in the assembly without changing the part file. Any tips? Using CATIA P3 V5 2019.

CATIA V5 cannot handle features (like a chamfers, holes, etc.) in an assembly - they must be added to the part only. So you need two parts: the detailed part, and one with the chamfer (assembly features).
So, once you have the detailed part finished and saved: Copy the PartBody, Paste Special, As Result With Link into a brand new file, and add the assembly features. Save this as the modified file, and use this file in the assembly. (any changes you make to the detailed part will show up on the second file and in the assembly)
