Autocad with gps setting

Inserting geographic location information to a drawing file makes points within the drawing correspond to geographic locations on the surface of the Earth.

Geographic location information in a drawing file is built around an entity known as the geographic marker. The geographic marker points to a reference point in model space that corresponds to a location on the surface of the earth of known latitude and longitude. The program also captures the direction of the north at this location. Based on this information the program can derive the geographic coordinates of all other points in the drawing file.
Typically a geographic location is defined by its coordinates (for example, latitude, longitude, and elevation) and the coordinate system (for example, WGS 84) used to define the coordinates. Moreover, the coordinates of a location can differ from one GIS coordinate system to another. Hence, when you specify the geographic location of the geographic marker, the system also captures the details of the GIS coordinate system.

Typically CAD drawings are unitless and are drawn at 1:1 scale. You are free to decide the linear unit a drawing unit represents. GIS systems, on the other hand, allow the coordinate system to decide the linear units. In order to map CAD coordinates to GIS coordinates, the system needs to interpret CAD drawing units in terms of linear units. The system uses the setting stored in the INSUNITS system variable as the default linear measurement of a drawing unit. However, when you insert geographic location information, you have the option of specifying a different linear measurement (for a drawing unit).

After you insert a geographic marker in a drawing, you can:

Make the program automatically determine the angle of sunlight when you perform sun and sky simulation (photometric studies).Insert a map from an online maps service in a viewport.Perform environment studies.Use position markers to mark geographic locations and record related notes.Locate yourself on the map in real-time on systems that support location sensing.Export to AutoCAD Map 3D, and expect the model to position itself automatically.Import raster files that contain geographic location information and expect them to position themselves automatically (This requires AutoCAD Raster Design).

Starting AutoCAD 2012, the Autodesk Exchange screen stays white and leads to the following error-messages: 'no internet connection'. But there is a connection. 'Autodesk server temporarily out of reach. Also not true because a colleague in another firm doesn't have the problem at the same moment. 'Your proxy is blocking Autodesk Exchange, contact your network administrator'. The Online Help isn't working either. See if you can install the cad manager tools from the dvd, and disable exchange. the in Options, set cad to NOT use online help. If you really need to use exchange or online help, you've got a browser that can get there.

AutoCAD Civil 2012 Object Enabler

The Civil Object Enabler is a freeware application that you can use to access AutoCAD Civil 3D drawing files. This release allows object data created in AutoCAD Civil 3D 2012 to be accessed outside the AutoCAD Civil 3D 2012 environment. Note: Extract the OE_HELP.zip file to your desktop or other location on your harddrive by selecting the file and Saving it to a desired location. Once saved, right-click on the file and select Extract All. Once extracted, proceed to review the OE_HELP.htm file for further information on the OE and installation. If you are installing on a 32-bit OS such as Windows 7 32-bit, Windows Vista 32-bit or Windows XP Pro 32-bit, please download the file Civil_2012_OE_32Bit.exe Download the file Civil_2012_OE_64Bit.exe if you are installing on a 64-bit OS such as Windows 7 64-bit, Windows Vista 64-bit or Windows XP Pro 64-bit. Attention Autodesk Storm and Sanitary Analysis 2012 Extension users: The AutoCAD Civil 2012 Object Enabler can also be applied to the latest release. Autodesk Storm and Sanitary Analysis is a 32 bit application, so you will need to install the 32 bit OE, regardless of your OS.
