Editable Topography from ARCHICAD to Revit

Recently came accross a situation where the Design Architect need to exchange ARCHICAD model with their project partners. The Main Contractor was using REVIT for their BIM process. So, there was a need for conversion of ARCHICAD model to REVIT model via IFC.

The project has large topography as it was a infrastructure project and all of them were created using Mesh object in ARCHICAD. When the topography was transferred to REVIT via IFC that becomes as a Model In-Place element which can not be edited easily. The Main Contractor requested for Toposurface which can be edited further in REVIT. This article covers the solution on how to re-create an editable Toposurface in REVIT using the data exported from ARCHICAD.

Creating Topography in ARCHICAD from AutoCAD Survey Data

Prepare the AutoCAD file

Open Surveyor’s dwg file and check whether it is done as per local practice/standards, for example:

  • Units = Meters
  • Block or Point is used to represent each survey point and placed at a correct global coordinate (X,Y,Z) – Use LIST command and pick the element to check


Now we are ready to Extract Data from the survey points.
