Hello, I have two parts that I want to isolate and drill holes with reference to each other in my assembly file containing 20 parts.

When i select a part and go to the editing phase 'there are features defined in the context of another assembly. You can edit the part, but you cannot create external references to valid assembly components.'' i came across this data screen.

As in other arrangements, the view of the part other than the part to be edited is not isolated and remains constant.

Does anyone have an idea as to the reason for this situation?
