The Complete AutoCAD to Revit Conversion Guide

This guide is part of the RapidPipeline 3D Formats Knowledge Database. It shows how to convert AutoCAD to Revit, if you'd like to know more about the formats, please check out the following links:

There are various ways to convert between AutoCAD and Revit. With RapidPipeline, you can easily convert and and optimize AutoCAD files, at scale. It supports Revit, as well as many other file formats (examples: 3dsMax, CATIA, Creo, FBX, glTF, Inventor, Navisworks, OBJ, PLY, Solid Edge, SolidWorks, STEP, STL, USD, USDZ, VRM), at high quality.

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

The AutoCAD file is a format mostly used for Industry-standard 2D and 3D computer-aided design software for technical drawing and drafting.
The Revit file is a format mostly used for Building Information Modeling (BIM) software for architectural design, engineering, and construction documentation.

The following limitations should be taken into account when converting AutoCAD files to Revit format:

AutoCAD Feature (not supported by Revit)	Limitation Details
Free-Form Surfaces	Free-Form Surfaces: supported in AutoCAD, but not in Revit. 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: supported in AutoCAD, but not in Revit. 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.

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 AutoCAD 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).
