Convert AVEVA to FBX in your application

3D InterOp is a CAD interoperability SDK that lets your software read AVEVA files and write FBX, carrying the mesh data across without re-tessellating it.

Spatial does not offer an online converter or a desktop conversion app. 3D InterOp is a component that software vendors embed in their own products.

AVEVA to FBX at a glance

Both formats store triangles, so the facets carry over without re-tessellation. The differences are in structure, appearance and metadata.

What's preserved, what changes

Here is what your application can expect to carry across from AVEVA to FBX.

Why software vendors add AVEVA to FBX conversion

Lightweight review

FBX carries tessellated geometry that opens much faster than the full CAD model, so design reviews and digital mockups stay responsive.

Sharing outside engineering

Marketing, training and sales teams rarely have CAD software. A FBX file gives them the shape in a format their tools can open.

Easier handling of large assemblies

Without exact surfaces and feature data, FBX files are easier to transfer and display, even for large assemblies.

Things to check before you ship

  • Written FBX versions: FBX 7.7.0.
  • Points and wires aren’t written to FBX.
  • The FBX writer is available through the UConnect interface only.
  • Supported AVEVA input: .rvm or .rvt files with their attribute files.
  • The AVEVA .rvt extension isn’t a Revit file: don’t route it to the Revit reader.
  • Test tessellation settings on your heaviest parts: finer meshes mean larger files.
  • Validate a sample of translated files in the target system your users actually work with.

Working with Spatial was a real milestone for us: Thanks to the powerful 3DInterOp library, we were able to successfully bring our complex CAD-based solutions to the cloud while remaining flexible to meet individual customer requirements. For us, Spatial is not just a technology partner, but a true enabler of our product strategy.

About the formats

  • Source format

    What is an AVEVA RVM file?

    RVM files are review models exported from AVEVA E3D Design and PDMS, the plant and marine design systems. They describe the plant geometry and hierarchy, with attributes in a companion file.

  • Target format

    What is an FBX (.fbx) file?

    FBX is Autodesk’s format for exchanging 3D scenes between content-creation, game and real-time tools. It stores meshes, materials and the scene hierarchy.

Frequently asked questions

No re-tessellation is needed. 3D InterOp reads the AVEVA facets as visualization data and writes them to FBX.

No. The FBX writer writes meshes; points and wires from the source aren’t written.

The FBX writer is available through the 3D InterOp UConnect interface.

No. The AVEVA .rvt extension isn’t a Revit file: route it to the AVEVA reader, with its attribute files.

3D InterOp reads .rvm or .rvt files with their attribute files, as visualization data.

3D InterOp writes FBX 7.7.0.

No. 3D InterOp reads AVEVA but doesn’t write it. To send data back to AVEVA users, write a neutral format they can import.
