      How to Convert a CAD File to GLB

      This article shows you how to convert a CAD model from common formats into a .GLB file for uploading into Canibuild. This guide covers what to include, how to maintain correct scale, & how to export using third-party tools for both FBX & Revit files.

      The only supported file format is .GLB with a maximum size limit of 20MB. This size restriction should include all embedded textures, geometry & materials. Any external folders for these elements will not upload.

      Model

      Include:

      • The main building or structure only.

      Exclude:

      • Landscaping, fencing, site boundaries, contours or lot data.

      • Driveways, paths or patios (unless shown on the floor plan).

      • Mirrored layouts or decorative extras not shown on the plan.

      Scale & Units

      • Export your model at 1:1 scale.

      • Use the same unit as your floor plan (Imperial or Metric).

      • Check that all measurements match the floor plan.

      • Do not upload mirrored models.

      Materials & Textures

      • All textures & materials must be embedded inside the .GLB file.

      • Do not link to external folders or material libraries.

      • Minor visual variations may appear in Canibuild’s viewer.

      • Use your first approved upload as a visual baseline.

      Convert FBX to GLB

      You can preview your .GLB file using this online viewer before uploading to Canibuild: 

       🔗 https://gltf-viewer.donmccurdy.com 

      • Open the Source file.

      • Clean up the model by deleting landscaping & unwanted 3D assets.

      • Zoom & rotate the model to check for & remove any floating objects.

      • Export the cleaned model as FBX.

      • Open the Image to STL website.

      🔗 https://imagetostl.com/convert/file/fbx/to/glb

      • Select FBX to GLB.

      •  Click Covert Model.
      • Select Download to save the .GLB file.

      •  Use the 3D viewer to confirm the output:

      This method will display only one solid colour & not detailed textures.

       

      Convert Revit to GLB with plugin LEIA

       

      You can preview your .GLB file using this online viewer before uploading to Canibuild: 

       🔗 https://gltf-viewer.donmccurdy.com 

      •  Open your 3D view in Revit.

      • Delete topography & any other unwanted elements.

      • Update materials using the Architectures plugin:
      • Go to the Add-In tab.
      • Use the Search feature to find materials (e.g. “roof”).
      • Select a material & click Import.

      Cross-check the total number of materials imported by selecting this in the Model option. Take note of the material count (e.g. GZ2ZOB).

      • Select the roof element in 3D.

      • Click Edit Type to access properties.

      To convert to GLB use the third party plugin LEIA.

      • Select the E-Verse option.

      • Click the LEIA icon.

      The LEIA interface will appear – match the settings to the example image provided.

      • Adjust the units (Metres or Feet).

      • Click Export.

      • Choose a save location.

      • Click Save.

      • Click Accept to finalise export.

      • Preview the final .GLB using the 3D viewer:
