![]() ![]() Copy and paste these values into the kml file you exported from Google Earth and use File Open to merge it in GE. Determine an appropriate offset and scaling value then use the Excel concatenate command to create the coordinates for the kml file. I find the Excel text to columns feature handy for this. You can use the Export IGS or if simple 2D geometry the list command to generate a list of x y points you can convert to lat/long with Excel. This should give you an idea of the format you need for creating your own kml file. I would start by creating a polygon of known size in Google Earth in the area of interest and saving it as a kml file. You would need to convert the AutoCAD coordinates to Lat/Long decimal degrees. It would be an interesting exercise to create a KML file from the line coordinates in your AutoCAD drawing. You may need the $500 Sketchup Pro version. See below.Did you consider importing the dwg file into Sketchup and then use Sketchup to position it in Google Earth? I don't believe the import features are included in the free version. You will notice that the surface is in the exact place and 10m above the Google Earth surface so we can actually see the Civil3D surface to validate. You can click on this entry and then click on the Model to have Google Earth travel to this model. Once you click on the View button, Google Earth will open and an entry will be placed on the left under your Temporary Places. Google Earth Pro can be downloaded here: Just make sure that you have Google Earth installed before the View command is issued. In the Nudge part of the wizard I purposefully added a 10m elevation to the surface so that its slightly higher than the actual Google Earth surface.Ĭlick next and then click View to View the Export. Then note in the Geo-referencing part of the wizard the coordinate system we selected in Civil3D earlier has been selected. Once the command is initiated an Export wizard is shown in which you can click Next for the first and second pages. Then Miscellaneous utilities and Export KML. To check if the surface placement is correct you can export it to Google Earth The tool to use is found in the Toolspace and the Toolbox tab. ![]() ![]() Now create the surface by adding the ‘All Points’ group as the surface definition. Just make sure this has been done by double clicking the mouse’s scroll wheel to do a ‘Zoom Extents’. The points should be imported and placed in the drawing area. Then select the appropriate point file format if it did not auto-select and click OK. Now that the drawing is set up you can import the survey points by selecting the ‘Insert tab’ and ‘Points from file’.Ĭlick the button button and browse to the points file. Please note that I set the coordinate system to Lo 29 WGS84 as datum as the survey data and surface I’m going to validate is located in that grid. This will enable you to set the Country and Coordinate system used which is quote important for the future exporting processes. Right mouse click the drawing name and click the ‘Edit Drawing Settings’. Then go the Civil3D Toolspace and click the Settings tab. In this case I used the South African Country Kit template and I saved the empty drawing, giving it a name. Next, pick OK to attach the image to Civil 3D. ![]() From the Import dialog you might pick the Fullscreen view option. You will need to zoom to the area of interest or enter the address to get to the right location. The first step is to open a new drawing using a template. In Civil 3D, from the IMAGINiT tab, within the Imagery/Terrain panel, select the Import from Google tool. In this blog I’ll take you through the process of creating the surface and exporting it to Google Earth for validation. The tool to do this is found in the Toolbox tab in the Toolspace as shown below. A suggestion was made to superimpose the newly Civil3D created surface onto Google Earth.Ĭivil3D had such a feature in previous versions but in the last couple of versions its slightly more hidden. I received a request from a civil customer wanting to validate his Civil3D surface to see if the surface that has been created is correct. ![]()
