Civil 3D is using the AutoCAD 2018 DWG format for at least one more year. Is there an echo in here? Didn’t I say that last year? And the year before? Yes, I said it back then and I get to say it again. Still the same DWG format and backward compatibility! Now that it has arrived, let’s take a look at some of the key things to know about this new version. As usual, new versions of Autodesk’s products have been released this Spring, including Civil 3D 2023! In addition to performance enhancements, Autodesk concentrated this year on adding or fixing functionality based on requests from the users.
