General Information
This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert IGES to Revit, if you'd like to know more about the formats, please check out the following links:
Converting and Optimizing IGES Files to Revit
RapidPipeline can import IGES files, but currently doesn't support exporting to Revit format yet.
If you specifically need Revit export functionality for your workflow, please feel free to get in touch with us - we'd be happy to discuss your requirements and potential timeline for adding this export capability.
If you need, you can import Revit files and convert them to any of these 8 formats: FBX, glTF, OBJ, PLY, STL, USD, USDZ, and VRM.
In the meantime, you can explore other options on the 3D Formats Knowledge Database, which might serve as suitable alternatives for your workflow depending on your target applications and use cases.

Limitations of IGES Files to Revit Conversion Workflow
The following limitations should be taken into account when converting IGES files to Revit format:
| IGES Feature (not supported by Revit) | Limitation Details |
|---|---|
| Free-Form Surfaces | Free-Form Surfaces Support: IGES: Full support | Revit: Partial support   Revit Notes: Limited NURBS support, primarily focused on building-specific forms and conceptual massing rather than complex organic surfaces. Impact: Free-form surfaces allow a CAD user to design surfaces with advanced controls over curvature and continuitiy. While these surfaces are common for CAD models (in the form of so-called boundary representations or "B-reps"), they need to be converted to polygonal triangle or quad data to work with most 3D rendering engines - a process called tessellation. In this example, a surface patch is used to describe a part of a curved surface of a product. Without support for this feature, the free-form surface has to be tessellated into quads or triangles. |
| Vertex Colors | Vertex Colors Support: IGES: Partial support | Revit: No support   IGES Notes: Limited color support for visualization Impact: Vertex colors allow the attachment of colors to each vertex of a 3D model. This can be useful in scenarios such as scientific visualization, or when converting/meshing data from a colored 3D point cloud, for example. On the polygonal surface connecting the vertices, the respective vertex colors are usually smoothly interpolated. In this example, different colors are attached to the different corners of a cube. Without support for this feature, the cube won't have any colors. |
What's the best way to get IGES files into my 3D applications, and are there alternatives to using Revit?
Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to IGES and Revit files - the conversion guide above provides a rough first idea about that. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to even automate the process for thousands or even millions of files.
Especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated tools and expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).
If you're interested to hire dedicated expertise from the best in the field to help your company reach your goals fast and reliably, please do not hestitate to contact DGG. Being the creators of RapidPipeline, and ambassadors for open 3D standards for more than a decade, we have been building some of the world's most advanced 3D pipelines, having processed many millions of 3D assets.
Therefore, our expertise will help you to reach your goals faster, at scale, and with the least possible friction, since we are focused on maximum interoperability.
