Gotta love Acad ... NOT!!!
I created a site plan (in BricsCAD) from an original Acad DWG file that a big architectural firm created for a real estate developer I work with. Have not had any issues with reading, writing or printing it at all (it's not an AEC file - they only want DWG's and it's been easier to just leave it in DWG and use Bcad). The file is made up of simple 2D lines - nothing fancy, no proxies, etc.
The drafter who works for the developer (who I've known for 20 years and is a good guy) asked for the file and I let him know where he could access it (on their network). He opened it up in his Acad 2013, saw the entities and when he went to zoom it - everything disappeared! I opened it up on my Bcad without any problems, imported it into Dcad without any problems, opened it in DraftSight without any problems, and imported it into Spirit without any problems. He tried a few other earlier versions of this drawing but with the same issues.
I downloaded the trial version of Acad 2017 and opened the file - with the same result (that, and the "this isn't a 'true' Acad file so we can't guarantee it will work" disclaimer Autodesk now includes when THEY didn't last write the file). No matter what I tried (and I've used/abused Acad since 1988 and Bcad since at least 2008) Acad would regen the screen and BLOOP - everything was gone. Autodesk TrueVIEW can display the file.
I tried round-tripping it through Dcad, but after exporting the DWG file it moved all entities to the "zero" layer. Whatever the reason, I was able to finally round-trip it through Spirit and back out to DWG that Acad **finally** read correctly.
Everyone can read and utilize DWG files - except for AutoCAD!!! Go figure ...
