Obtaining Civil 3D information

“

- [Instructor] If you want your Revit project to be coordinated with your site, you need to put it on shared coordinates. I'll just say it now. I prefer not to be in shared coordinates because I personally think Revit doesn't do a great job with it. It's kind of sloppy and you can get into trouble if your entire team isn't paying attention. The objective of this video is to go find an AutoCAD, civil 3d drawing, and see where the geographical information is. Let's open up any version of Autodesk, civil 3d. We should come to the start screen. Let's click open. Browse where you're keeping your exercise files or find any civil 3d drawing you'd like. I'm going to grab this base site drawing in my chapter one folder. Click open. Very common, if you copy or move an AutoCAD drawing, generally it's going to lose some external references. In this case, let's just ignore unresolved reference files. Now it looks nice and clean but the first thing I want to do is just double click your wheel button on your mouse or you can type Z+A+enter to zoom all. Notice that our extents are massive from zero zero to wherever our site is located. This is miles away. Revit doesn't like those giant coordinates. I'm going to click undo right here to bring us back to our actual view. We'll clean this up in the next video but right now I just want to look at the geographical information. Up here notice I have a tool space. I'll close mine in case you don't have yours. In the command prompt type in tool space and hit enter. That should bring up your tool space. Now make sure you're on the settings tab right here. Notice that it has the actual file name and then all the civil 3d stuff underneath it. If you right click on this one, two, three, four, five, six seven base site, go to edit drawing settings here. We'll see what the deal is. I see that it's yes. On feet. The scale I don't care about. That's just specific to this viewport, but notice that it's USA New York and it's 83 New York state plains central zone US foot NY 83. This is what I'm looking for. This is good information. Hit Cancel. Now, if it's not on a state plane you should probably talk to your civil engineer and see if they can get it on state plane. Once they do, we can now bring this data into Revit. But before we do it let's clean this thing up in the next video.
