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.
