• Open or hide all doors to ensure access to all areas.

• Add a ground plane to facilitate navigation. Limit thickness to 20mm.

• Purge file to remove unnecessary elements.

• Check texture requirements for compatibility and quality.

• Check file type size limitations to avoid errors.

Design & Build XR supports the following native platforms and file types:

• Revit (.rvt)

• SketchUp (.skp)

• 3ds Max (.max)

We also support these platforms as non-native files:

• ArchiCAD

• Rhino

• Blender

What does that mean?

You will need to export your file as one of the native formats.

Remember to check the following guides for your model. This is the same across all file types.

• Open or hide all doors to ensure access to all areas.

• Add a ground plane to facilitate navigation. Limit thickness to 20mm.

• Purge file to remove unnecessary elements and delete geometry that is not in view or off to the side.

• Glass must use translucent material with over 80% opacity.

• Adhere to size limitations:

  • Model's x, y and z axis does not exceed 500m/1640ft

  • < 4 million triangles

ArchiCAD

We suggest exporting your file as a .skp (SketchUp).

To do this follow the below instructions.

1. Save a copy of your model

2. Make sure you have applied the general guidelines (as above)

3. Remove any 3D views that are not applicable

4. Purge your file

5. Select 'Save As'

6. Change the file type to '.skp'

7. Select okay

Check your settings in ArchiCAD to ensure relevant elements are showing. While in this prompt box, check your polygon counter does not exceed the limitations (approx. 4 million)

Enscape in ArchiCAD

Please note that Enscape furniture, textures and other elements will not transfer across to Design & Build XR. We strongly recommend you remove any Enscape objects and replace them with a native file type.

Rhino

We suggest exporting your file as a .skp (SketchUp).

To do this follow the below instructions.

1. Save a copy of your experience

2. Make sure you have applied the general guidelines (as above)

3. Purge your file

4. Select 'Save As'

5. Change the file type to '.skp'

6. Select okay

It is recommended that you convert geometry to a mesh however may not be necessary.

Blender

Blender does not have a direct way to save as or export to an Enviz native file type (.rvt, .skp, .max).

If you have a Blender model and have access to 3ds Max or SketchUp we suggest you try the following flow.

1. Save a copy of your experience

2. Make sure you have applied the general guidelines (as above)

3. Purge/Clean Up your file

4. Select file and then Export

5. Change your file type

   1. SketchUp = Collada (.dae)

   2. 3ds Max = FBX (.fbx)

6. Import your file into the appropriate program (SketchUp or 3ds Max)

7. Save

Other file types

Currently, Design & Build XR only supports native file types for Revit, SketchUp, and 3ds Max. If your software allows exporting to one of these formats, you may be able to use it with Enviz. However, compatibility may vary, and some model geometry or textures may not convert correctly.

Please follow the requirements below for all file types. We strongly suggest you

make a copy of your file before proceeding.

Open or hide all doors: Ensure doors are open to allow full accessibility in VR,

you will not be able to walk through a closed door.

Add a ground plane: Include a plane for navigation around your model. The

plane should be limited to the bounding box size (500m x 500m x 500m) and a

thickness of 20mm.

Delete irrelevant elements: Remove out-of-view geometry, unused 3D views,

and hidden/frozen layers containing elements you do not wish to show.

Purge files: Instructions for purging are included below.

Triangle limit: Your model must not exceed 4 million triangles. In each of the

modeling software sections below we detail out how to measure this.

Bounding box: Your model must fit within a 500m x 500m x 500m (1640ft x

1640ft x 1640ft) box.

File Limitations

There are limitations on the size and complexity of files that can be processed. Currently we support average size houses and apartments. If your project is larger you can continue to upload your files however, you may encounter errors. Ensure your model aligns with the following requirements to avoid errors:

• Model Size: Follow size limitations specific to your software.

• Scope and Complexity: Refer to software-specific guidelines.

• Error Logs: Use error logs to identify and fix issues if your model is rejected.

Size limitations

Important: Ensure all scope boxes are turned off before submitting your files.

• Triangles: Less than 4 million. Directly measuring this in Revit isn't possible. When you submit your model to our process we will provide feedback on the triangle count. Generally, when this is an issue for Revit models reducing the number of objects with highly detailed geometry would help resolve this issue.

Please ensure your model does not exceed the limits outlined. Our system will allow

you to upload your file, however, it may be rejected or take a longer time to process.

If you are unsure of any of the limitations, please reach out to us.

Selecting the Correct 3D View in Revit

To ensure the correct view is selected for your immersive experience, follow these steps:

1. Default Behavior

If your Revit file includes a view named {Default 3D View}, DBXR will always use that view. This is the system’s highest priority.

2. Choosing a Custom View

If you want DBXR to use a different 3D view:

• Delete the {Default 3D View} from your Revit project first.

• DBXR will then select the first 3D view listed alphabetically from the remaining views.

• To control which view is chosen, rename your desired 3D view to appear at the top of the list—e.g., rename it to something like "1A_PresentationView".

3. Summary

• Keep {Default 3D View} if you want it to be used.

• Remove it and rename your preferred view (e.g. "1A_YourViewName") to have full control.

Textures

DBXR supports both Autodesk and customized textures. Please review this document carefully to ensure you are following the applicable guide.

Important! Materials with applied transparency will be shown as such. Ensure only objects like glass have a material with transparency applied to them.

Autodesk Textures

Standard Revit textures are automatically supported, simply upload your .rvt file. To preview the output of textures before submission, navigate to the bottom left panel in Revit and set your Visual Style to Realistic Textures.

If you have added specific textures to your project, follow the process under Customized Textures.

Customized Textures

Customised Textures

For models with custom textures, submit as a .zip file containing the .rvt file and all associated texture files.

Unfortunately, Revit does not currently have a quick method of locating and packaging all these textures so it will need to be done manually.

To locate custom textures:

1. Open the material browser: Edit Type ➔ [...] On the top surface.

2. For each material in the matierial browser

a. Look under Generic ➔ Image.

b. If an image is present open the image and locate the texture.

No Textures (White Models)

As many Revit families and structures will have a standard material applied to them,

you may wish to remove this and show your experience as entirely white.

To create a white model:

1. Duplicate your file.

2. Open the material browser (Edit Type > [...] On the top surface).

3. Edit one material (or choose an existing material that is white with no textures.)

a. Delete any material/texture

b. Show the existing color

4. Delete all other materials

5. Purge Unused

Exporting

There is no specific requirement for exporting your Revit file.

For Autodesk Textures, save your Revit file and select the latest .rvt to upload.

For Customised Textures, save your file into a .zip including associated images.

Important - Prior to submitting your files we strongly recommended completing a Purge Unused process to remove any unwanted elements in your model. Manage

Tab ➝ Purge Unused.

Size limitations

Triangles: Less than 4 million. When you submit your model to our process we will provide a specific measurement, but in SketchUp doubling the "face" count would be a reasonable guide.

Please ensure your model does not exceed the limits outlined. Our system will allow you to upload your file, however, it may be rejected or take a longer time to process. If you are unsure of any of the limitations, please reach out to us.

Important! Materials with applied transparency will be shown as such. Ensure only objects like glass have a material with transparency applied to them.

Exporting

Simply drag and drop your .skp file or select it from your within file explorer folder.

Important - Prior to submitting your file we strongly advise you complete a purge unused process to reduce any unwanted elements in your file. Select Windows ➝ Model Info ➝ Statistics ➝ Purge unused.

Size limitations

Please ensure your model does not exceed the limits outlined below. Our system will allow you to upload your file, however, it may be rejected or take a longer time to process. If you are unsure of any of the limitations, please reach out to us.

• Triangles: Less than 4 million.

While in 3ds Max, press 7 on the keyboard to open the viewport showing the triangle (tri) count of the active view. Please note that the reported count does not factor in instanced objects. To ensure you get an accurate triangle count, we recommend un-instancing your objects.

• Maximum objects: 100,000

Max: File > Summary Info

Textures, Materials and Lighting

Currently, we support color & opacity textures. We do not support any custom lighting. The output will produce an even lighting setup with some basic ambient occlusion to help highlight form.

See below the current support for materials:

Supported Materials:

• Multi/Sub-Object (Containing the below materials)

• Standard (Legacy)

• Physical Material

• Corona Physical

• Corona Legacy

• VRayMtl

Supported Properties

• Color/Diffuse (Value or Map)

  Alpha/Opacity/Transparency (Value or Map)

Additional TLDR

Models should be no larger than a large house. City blocks or campuses will not currently work even if they are within the tri budget.

Exporting

White models

There are no specific requirements for white versions of 3ds Max files. Simply save the latest scene, checking that it aligns with the requirements above. Drag and drop this .max file or select it from your file explorer.

Textured models

To capture the textures and materials you will need to archive your scene so it saves as a .zip file. Drag and drop this .zip file or select it from your file explorer.
