I have the same issue. Only since SP3 was installed.
I have contacted my VAR and the issue has been noted. It appears to be an issue with the edges of circles. They should be looking to fix this in the next service pack, but the best work around I have found is to save an eDrawing through the eDrawings application. If you continue to have issues, I would suggest contacting your VAR so they fix this as quickly as possible. Here is the body of the email:
I found out that the issue with saving to eDrawings is a regression issue with 2017 SP3. There is an SPR 1024994 assigned to fix it, you have been added to the contacts for when this completed.
It appears the issue is related to circular edges /holes. If they were removed it would work, but this is not a work around more of an observation.
Work around's include opening the assy in eDrawings directly and saving to easm. The issue is not present in 2017 SP2 so reinstalling that on one computer could also be a solution.
I can't remember the sequence, but there are two SPR's for this issue, I believe that they "point to each other", but one of them is the "active one" - I think the number that I posted may be the "cancelled" one, and your VAR sent you the current SPR#.
Really hope this gets fixed in SP4.0 - this is a drag . . .
You can create an eDrawing by opening the SolidWorks file in eDrawings, and then saving it as an eDrawing from there.
Bonus: No crashing!
Ya we've been working around it by opening the files in EDrawings and saving out that way. Just a pain. Hopefully it gets resolved next SP
