To use VTK (Visualization Toolkit) files inside Alibre Design, you must install a specialized data exchange add-on or pre-process the files. Alibre Design does not natively open .vtk files through its default installation. Method 1: Use the SYCODE VTK Import Add-on
The most direct way to load VTK data is through third-party plug-ins like the VTK Import for Alibre Design developed by SYCODE.
How it works: The add-on integrates directly into the Alibre interface, allowing it to read 3D coordinate and mesh data stored in VTK files and reconstruct them as native Alibre geometry.
Step 1: Download and install the compatible add-on installer for your version of Alibre Design.
Step 2: Open Alibre Design and navigate to the Add-Ons tab or use the standard File > Open dialog.
Step 3: Change the file type dropdown menu to VTK Files (*.vtk).
Step 4: Select your file and click Open. The add-on will read the points/polygons and generate a corresponding model or point-cloud mesh. Method 2: Convert VTK via FreeCAD or MeshLab
If you do not have a dedicated plug-in, you can use open-source intermediate tools to convert the VTK file into a standard format that Alibre fully supports (like STEP or IGES).
