Man, that's sad, sorry to hear it!
What does the underlying part look like?
Is it still the same as it was when you finished making it, and used it to make the drawing?
If not, then maybe you can find one of the old files in the 'OldVersions' folder.
You can copy the most recent 'old' file to the main folder, change the last numbers to something that makes it slightly different from your original file, and then open it and see if it's the same as your finished part. If not, then go to the next older one in the 'OldVersions' folder, and do the same, and so on until you find one that's correct, or at least close to correct. Then close the drawing, rename the offending part (don't delete it!) so you know it's defective, and then rename that good part (from the 'OldVersions' folder) to the part you just renamed, and then reopen your idw file.
I've had this happen to me (did it to myself! not saying you did that though) a few times over the years when I got tired from overworking in the corporate slave colonies. What happened is, I manually copied a part that was open in the editor, and then planned on making a different version of that part out of the new part, but mistakenly changed THE WRONG PART! Then I had t go through all this (above) to just get my project back on track, b/c I accidentally deleted or over-wrote my old good part!
