Looking for a way to import or export STEP, CATIA, SLDASM and more file formats from and into BricsCAD®? Then you need the Communicator for BricsCAD. It seamlessly imports product structure geometry & PMI data from all major CAD applications.

Exchanging data with other CAD systems is a very important feature of BricsCAD! It is in our DNA to edit imported geometry with the same flexibility and parametric power as the native one.


Watch the Tutorial: Assembly design using BricsCAD Communicator


The BricsCAD Communicator is an optional plug-in for the Pro, Platinum, BIM, Mechanical and Ultimate editions of BricsCAD that imports and exports 3D data between major CAD formats. Its high-quality translations facilitate the re-use of 3D CAD data, improving productivity and reducing project costs.

Importing Assemblies

It is possible to import not only the geometry but also the product structure from other CAD assembly files. When you import an assembly file, you can get its content as a plain geometry (a nonhierarchical set of entities) or map its product structure into native blocks or mechanical components.

You can navigate through the product structure using the Mechanical Browser. Imported parts and subassemblies are represented by local components.

 model communicator assembly

PMI (product and manufacturing information) is supported for the following file formats (Communicator license is required): ACIS, CATIA V5, NX, Pro/E / Creo, SolidWorks, XCGM. PMI annotations are imported as graphical elements grouped in blocks.

If the assembly contains hidden parts (only for CATIA v5 export & import), you can decide how to represent them in BricsCAD: ‘import and hide’, ‘import and set visible’ or ‘do not import’. Change this in the Settings dialog:

import assemblies to BricsCAD

You can also set other import options to automatically repair, stitch and simplify imported geometry. If you import a 3D model from SolidWorks, BricsCAD automatically maps the Y axis to the Z axis (because in SolidWorks the vertical axis is Y).

Example imported model

For SolidWorks and other native CAD formats, it is possible to specify an alternate search path, which will be used to look for parts absent in the imported assembly folder.

Exporting Assemblies

You can export a BricsCAD assembly with mechanical components as a file with product structure. To do that set the desired value in the Settings dialog:import settings
