The very first step is to cut your BIM model with buyer options into “lego bricks”, or a gridfield. This gridfield is a smart collection of the buyer options and is placed in option cells. The gridfield is built into your BIM software package. You can use various BIM software packages for this, such as ARCHICAD and Autodesk REVIT.
We personally prefer Autodesk Revit, also in view of our bi-directional coupling. This link also ensures that selected buyer options are automatically read into Autodesk Revit.
