3D DWG to BIM Track

If you grew up in the 90s like many of us, you witnessed the rise of new technologies, such as cable television, the World Wide Web for the general public and the growing use of CAD. Today, BIM is replacing CAD; however, moving away from CAD can involve many challenges. It can be a long process to implement BIM, and companies may still be working with 3D DWG as part of their coordination and fabrication process because it has been a successful solution in the past. In this type of hybrid environment, CAD coexists with BIM. This blog post goes through the basic steps of importing a 3D DWG in BIM Track using Revit. Purists, close your eyes.

Let’s start with that 3D DWG file of different MEP systems in AutoCAD.

Non necessaire. Can reword to provide the benefits of your steps vs the purist solution?


We are going to use Revit as a platform to convert this 3D DWG to an IFC (industry foundation classes) file. First, open Revit, create a new family, and select the generic model family template.

Import the 3D DWG in your family using the following options (Note that we had some issues with the auto-detect feature under the Import units. It is better to specify the unit manually.).

Here is the imported DWG in the family.

Place the family and align it with the grid lines. Make sure the shared coordinates are set as per the other models previously uploaded to BIM Track.

Export the model to IFC2x3.

Import the IFC file into BIM Track. The model should now appear as one big element. This is because the DWG format is not object-oriented.

This quick and easy way to import non-BIM data, such as like a 3D DWG file, into BIM Track can help you interface with other professionals and provide sufficient information for understanding the project scope and improve coordination between teams.
