My project page says AutoCAD can't open my drawing.

When AutoMEP opened this file, it stopped with a read error. That usually means part of the drawing is damaged, and it can happen even when the file opens on your own computer. Jobs on that drawing are refused before they start, so trying one doesn't use any of your plan. To repair it, open AutoCAD, type RECOVER and choose the file. Once it opens, type AUDIT and answer Yes when it asks whether to fix errors. Save the drawing, then upload the saved copy to your project and run your request on the new upload. If the repaired copy is still refused, use the form on this page and we'll take a look.
