With our drawing attached, we can now go about configuring a query. Once you have found the drawing you with to convert, select it and press the button. The resulting dialog will allow you to browse to your original drawing in the other coordinate system. If it is not already open, you can use the MAPWSPACE command to turn it on.įrom the "Map Explorer" tab Right-Click on "Drawings" and select "Attach" With my coordinate system set, I will now open the Map Task Pane. The button will also allow you to browse for any of the included coordinate systems. That being the case I will enter VA83-SF as my code. In this example I have a drawing in NAD27 Virginia State Plane South (VA-N), and want to move things to NAD83 Virginia State Plane South Feet (VA83-SF). From here we’re going to assign the datum to translate your existing drawing to. Using the "Map Classic" workspace, go to Map > Tools > Assign Global Coordinate System.
While it may seem odd, we’re actually going to start the translation from a blank drawing. Users of Map 3D naturally know it’s power, whereas I have found many civil engineering professionals nearly forget about the Map menu altogether. As you may know both AutoCAD Land Desktop and AutoCAD Civil 3D are built on top of AutoCAD Map 3D, so if you have either product, you also have Map 3D. To answer that I turn to good old Map 3D.
Whatever the case may be, how might one perform this translation as accurately as possible? A classic example may be moving from a NAD 27 datum to a NAD 83. For one reason or another drawings sometimes need to be moved from one coordinate system (datum) to another.
