I deriver, with mirror, a part.
Now i enlarged holes in the source part, but there was an error message in the derived part that the export status of the source isn't on, and that i should use design doctor.
Where is the control on the export status and what is it, i didn't see anything unusual in the parameters.
Where is the design doctor.
I cannot make new holes in the derived part in the place of the old ones since it says i have first to exclude the source.
The parts are attached
Not sure what the problem is, but if i accept the error and then "edit derived part" only to click ok (without changing anything) the problem goes away.
i can even edit the holes and update normally after that.
I did have some issues with downloading your parts, as it did not recognize the filename.
So i named them 1 and 2.
If what i did doesn't work for you, maybe check if it's a filename problem?
