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

There are various ways to convert between IGES and Revit. With RapidPipeline, you can easily convert and and optimize IGES files, at scale. It supports Revit, as well as many other file formats (examples: FBX, glTF, OBJ, PLY, STL, USD, USDZ, VRM), at high quality.

Below you can find a video explaining how to convert your files:

What are IGES and Revit files commonly used for?

The IGES file is a format mostly used for CAD data exchange and interoperability.
The Revit file is a format mostly used for Building Information Modeling (BIM) software for architectural design, engineering, and construction documentation.

0 - Limited NURBS support, primarily focused on building-specific forms and conceptual massing rather than complex organic surfaces.
1 - Limited color support for visualization
2 - Basic material properties and annotations
3 - Assembly relationships with limited constraints
4 - Basic entity relationships and grouping
5 - Legacy format, superseded by STEP in 1994
6 - Uses proprietary RVT and RFA formats but provides import/export capabilities for industry standards like IFC, DWG, and other BIM/CAD formats for interoperability.
7 - Basic UV mapping capabilities through material properties, primarily for architectural visualization rather than complex texture workflows.
8 - Limited procedural texture support through material definitions and appearance properties for architectural visualization.

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

Free-Form Surfaces illustratedlack of support for Free-Form Surfaces illustrated

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

Vertex Colors illustratedlack of support for Vertex Colors illustrated

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.
