Construction and calculation functions (COGO) can be used with enterprise industry models in AutoCAD Map 3D toolset and AutoCAD Map 3D 2026 toolset.
Construction functions have direct access to the enterprise industry model. Existing coordinates are retrieved and results are directly stored in the database.
Optionally you can generate detailed construction reports.
You can use the COGO commands in an industry model that is 3D-enabled, however the following commands do not support 3D: Arc Intersection, Orthogonal Calculation, Polar Calculation, Offset, Right Angle Course, Free Standpoint.
Projects can be created and configured with Infrastructure Administrator .
Basic Handling
Construction functions work in close interaction with AutoCAD Map 3D toolset and AutoCAD Map 3D 2026 toolset commands. There is a frequent interchange between the Autodesk command line and the construction dialog boxes and you provide input to both.
- When you start a construction command, you normally are prompted to select the elements in the drawing or in the map. Be sure to watch the command line.
- All elements of the calculation (such as arcs, circles, and points) appear temporarily in the drawing.
These elements are enterprise industry model features and are stored in the database.
- As soon as the required elements are selected, the focus changes to the relevant construction dialog box.
- The construction dialog box displays all construction elements, parameters and results, such as point coordinates, radius, or distance. You can modify the parameters and calculate again.
- After the re-calculation the drawing is updated with the new result.
- When you are ready, you can save the result in the database.
If you press <ESC> instead of selecting an element, the construction dialog box is displayed immediately without prompting.
Some construction functions have no dialog box and run completely through the command line.
