I have a model rebuild error appearing in a single drawing view of a part and cannot get to the bottom of what is causing it.

Attached is a screenshot of the problem.

Model 305N51014 is showing a rebuild error in drawing view 1, but the same model shows no error in drawing view 6. Opening the model itself reveals no errors. This is not the first time i have had this issue.

Can anyone shed any light on why this might be happening?

Thanks.
