I’m usually able to figure things out for myself, but this time I’m stumped. Just got a .dwg from the surveyor, which includes some rudimentary 3D geometry of the roofs to aid me in constructing a more accurate model of the subject property and adjacent buildings. Imported it into 2017 but was having some problems, so saved the part I needed as v2016 and opened it there, since I haven’t spent any time in 2017 yet. Same problem in 2016 though.
Numerous problems with using the file. In orbiting, some or all of the geometry disappears and reappears. It’s entirely edges, no faces, but some lines can be selected by clicking on them, others I need to click a little distance away. Try to make faces from them, and inference cues tell me I’m on a point, but when I click to start a line or rectangle, it’s not actually on the point. If I do manage to start a line along one of these lines, and connect it to a line on the opposite side, the existing line gets pulled over to meet the point that wasn’t actually on the line, though it does create a face. As imported, it had around 100 layers, but putting everything into Layer 0 didn’t change anything. There doesn’t appear to be any hidden geometry.
File was too big to upload, so hopefully this link will get you to it on dropbox.
Thanks in advance for your help!
