How to draw as-built models of angular surfaces

Modified on Thu, 25 Apr 2024 at 04:06 PM


With NUBIGON, you can draw as-built plans of angular surfaces like roofs based on point clouds.  


Trace the surface with a drawing

  • Align the camera  to the surface and switch the camera type to orthographic.  
  • Launch the Drawing tool from the sidebar. Set the Drawing Plane to Free. 
  • Choose the desired Drawing Object (Polyline, Arc, Circle, and Point) and start drawing. 
  • Once you exit the drawing mode, a new drawing object will be created. 
  • To edit the drawing further, select it from the Object list, and ensure Viewport editing is enabled. You can now modify the edges and vertices of the drawing. 

Export the as-built plan 

  • Select the finalized drawing, then go to File > Export > Export CAD and name the file. 
  • To export the drawing in the same coordinate as the point cloud, choose the point cloud from the Offset dropdown. 
  • Click Save and export your file. 


Finally, export your section plan into a DXF or DWG file. A step-by-step guide is described here.
