Then says 'specify the north direction or (angle):s, then 'Point or option keyword required'.Ĭan someone suggest a way to have the ability to draw subdivision lines on satellite imagery.
When I select 'continue' the command ribbon asks that I, 'select a point for the location :Ĭan someone please explain what this means? I have looked at the co-ordinates on google earth and attempted to enter but it does not feel right. Then a window appears which says 'Navigate to the location in Google Earth that you want to import before continuing (for best results, configure the view in Google Earth to look directly over the location that you want to import). In the 'type a command' ribbon, when I type in 'GEOGRAPHICLOCATION' and select 'Import the current location from Google Earth' (opens Google Earth, where you can retrieve a location to import). I wish to use Autocad to draw subdivision lines and need to overlay satellite imagery (Google Earth or Google Maps) in tandem with Garmin GPS waypoints taken in the field. Compare that with what you get out of Google Earth.I am using Autocad LT 2013. Check out this example, in the following image you can see where four of the images downloaded from the Seamless server line up and it’s REALLY close to being exactly matched up (I can’t see any offset or other error personally). Getting the data yourself takes a bit longer but you get MUCH better results. Importing from Google Earth is fast but you get very poor data.
Sure this process takes longer then importing from Google Earth but think of it this way, “You get what you pay for”. Proficiency in 3D structural analysis software and design software Practical knowledge of foundation and structural analysis software Knowledge of transmission and distribution in LV, MV and HV Working knowledge of AutoCAD and Microsoft Office Suite Working knowledge of Civil Cad3D (2014-2020), AutoTurn 8. This will bring the images in georeferenced. To bring the images into Civil 3D, use the Map Image Insert command MAPIINSERT (yes, two I’s in there). Also make sure you read the comments as you’ll need create the surface in a metric drawing and use LandXML to bring it into a drawing that is in imperial units.
When you add the DEM file, use the coordinate system code LL83.
I’m not going to get into the details in the post as I’ve already talked about how to bring DEM files in to Civil 3D. To bring the DEM file into Civil 3D, create a surface and add the DEM file as data. When you get to, on the left hand side, there is a panel and on this panel, is a link to the Seamless Viewer (you can access it HERE if you like).
You’ll need to create an account to download the data but it’s free. aerial images) as well as surfaces (DEM files).

Here you can browse a map to find your project location and download orthoimagery (i.e. So, instead of relying on Google Earth, go out and get the data yourself! You’ll be much happier with the results.įor those of you with projects in the United States there is an amazing resource that I was familiar with but never really investigated much, the USGS Seamless Data Warehouse (I was playing around with the Autodesk Infrastructure Modeler and looking for data). This may seem inconsequential to many, however it is an absolute life saver in so many workflows. Civil 3D 2013 will not have Google Earth extensions. Sure, you can pick anywhere you want but you are limited to importing 5,000 points and, if you have a large area, that’s not very much data at all (I recently downloaded a DEM file with over 2.5 million points, now THAT’S data!). While there are a few nice enhancements in Autodesk’s AutoCAD Civil 3D for 2013, unfortunately there seems to be something missing. The surface data that you bring in is very limited. The guys over at Being Civil wrote up a nice post about this issue HERE if you are interested (also, the images come in black and white). First of all, the imagery is inconsistent at best. There are two primary issues that I’ve seen when importing data from Google Earth. I’m constantly amazed at how many people import data from Google Earth into Civil 3D and then complain about how horrible the data is. So for those who are using autocad civil 3d 2013, there is not yet a solution for this problem.
Note from Brian: There’s some new functionality in the 2015 release regarding images. As for now, import and export of imagery from google earth to autocad civil 3d 2013 is not yet supported because of they didn't include the google earth api on this version of autocad due to the limitation of google earth api.
