Question

Tangency lines not showing in a drawing view

Hello group,



I am having a problem with tangency lines not showing in an assembly drawing when the view is no hidden lines. In the same drawing I get a view where a portion of a section view is blank too. I have seen this behavior before, but I never found the fix because it was not critical for that particular drawing. This same drawing looked fine before I made some geometry changesand alsochanging the accuracy for some of the parts. Attached is an image showing the partial blanked out area of a section view. Any suggestions will be greatlyappreciated.



Sincerely,

Hi Mark,
Have your geometry changes resulted in an interference condition between
two parts? This causes ProE to interpret hidden lines incorrectly - it
may also be affecting the tangent lines in your case.

Sections can fail when there is a surface coplanar with the cutting plane. Sometimes a curved surface tangent to the cutting plane too. Try moving the cutting plane slightly.
