Features

DXF site plan export

Get a clean DXF of a site to start drawing in AutoCAD, BricsCAD, ArchiCAD, Revit, Vectorworks or Rhino, in metres and on layers you can switch off.

Try it in the studio How it works

What you get

Named layers
CONTOUR_MINOR, CONTOUR_INDEX, BUILDINGS, ROADS_MAJOR and more, with closed polylines for buildings and water.
Real elevations
Contours sit at their height, so Civil 3D and Revit can build a surface from them.
Coordinates
Local metres from the south-west corner or the centre, or UTM, stated in the README in the download.
Also 3D
DXF 3D faces of terrain and buildings, and IFC 4 for BIM.

How to do it

  1. Draw the area and generate.
  2. In Export, choose DXF 2D (and 3D if needed) and the coordinates.
  3. Download; several formats come as one ZIP with a README.
  4. In CAD, insert in metres, origin to origin.

Limits to know

DXF R12 is used for compatibility; there are no hatches or dimension entities, and text uses the standard font of your CAD program. More on the data and accuracy page.
