Extrusion Properties are Changed when an Unrelated Sketch Dimension is Changed

[Anonymous]

I'm encountering a problem in which an extrusion that it referenced to a work plane is automatically ruined when I alter a line length in an unrelated sketch. I receive an error saying the extrusion distance is zero despite the extrusion being referenced to a work plane that is several inches away rather than referenced to a specific distance. Please see attached screenshots.

But, is that line segment associated with the extrusion properties somehow?  Maybe through project geometry in the sketch?

Can you post the Inventor file, pictures don't tell the whole story

Hi! The error message indicates after you changed the dimension, the extrusion distance becomes zero. There must be some relationship between the distance and the dimension you changed. Please attach the file here. We are not good at guessing.

Many thanks!
