Working with DXF Design Files

Upload a DXF file to your site

From the DESIGNS Tab, click IMPORT A DESIGN.  Designs can be uploaded in DXF, TTM, KML, KMZ, LandXML (CgPoints and Surfaces only), or IFC format.

Other file types will be added to the OUTPUTS tab, under Files.


Working with DXF files

Supported DXF entities include Arc, Circle, Dimension, Ellipse, Face, Line, LWpolyline, Mesh, MText, Point, Polyline, Solid, Spline, and Text.

Once imported, several features are available to help customize, visualize, and compare your site against the design file:

Archive and rename individual layers within a DXF file.


Clamp linework to the ground.


Use Compare to Design to measure the volume between your latest survey data and the design surface. 

Enable overlay of terrain against a 3D surface.


Convert your DXF to measurements

Convert the entire DXF surface at once

When you upload a DXF surface we auto-generate a polygon boundary that outlines your DXF surface. To convert this to a measurement, right-click on the dashed yellow line. 

Convert single or multiple elements within the DXF file 

To convert a single element within the DXF right-click and select CONVERT TO MEASUREMENT.



If you wish to convert multiple elements at once, for example, to convert several cross-sections at stations or chainage positions along your road alignment, then hold down the shift key to bulk select the elements you wish to convert.

Export a measurement as DXF 

Measurements created on your site can also be exported in DXF format:

  • Export the outline of a polygon or polyline measurement.   
  • Extract a section of your surface as a TIN surface model (3DFACE).
