General
This guide provides the necessary steps and recommendations to ensure your model is ready for Space AI. Proper setup ensures smooth processing and the best possible output.
Space AI supports the following platforms and file types:
Revit (.rvt)
SketchUp (.skp)
3ds Max (.max)
To get your experience Space AI ready, please follow the guides below. Make sure to read through the requirements carefully to achieve the best outcome.
Model Requirements
Please follow the requirements below for all file types. We strongly suggest you make a copy of your file before proceeding.
Open all doors to access areas of your model. You will not be able to walk through a closed door.
Place a ground plane in your scene to ensure you can walk around your model. The plane should be no larger than the maximum bounding box / scope box size (outlined below) and limited in thickness. We suggest 20mm.
Delete anything not relevant in your file. This includes geometry that has been placed out of view, 3D views that are not relevant or hidden/frozen layers that contain elements you do not wish to show.
Purge your files before submission. You can find exact instructions on purging below.
File Limitations
Space AI has 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, it may throw an error state. Ensure your model aligns with the following requirements to avoid errors:
Model Size: Adhere to size limitations specific to your software.
Scope and Complexity: Review the relevant software guidelines for detailed limitations.
Error Logs: If your model is rejected, review the provided error logs to identify and correct issues.
If you have any questions, contact us at [email protected].
Revit Guidelines
Size limitations
Scope box: 500m x 500m x 500m (1640ft x 1640ft x 1640ft)
Important: Ensure all scope boxes are turned off before submitting your files.
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 at [email protected]
Glass and Transparency
Glass layers must use translucent materials with over 80% transparency.
Opaque material settings will appear as solid objects.
3D Views
Your revit scene should only contain 1 x 3D view.
If you have multiples, remove whichever ones you do not wish to show or re-name your default to {3D}.
Textures
Enviz Space AI supports both Autodesk and customised textures. Please review this document carefully to ensure you are following the applicable guide.
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 Customised 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:
Open the material browser: Edit Type ➔ [...] On the top surface.
For each material in the matierial browser
Look under Generic ➔ Image.
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:
Duplicate your file.
Open the material browser (Edit Type > [...] On the top surface).
Edit one material (or choose an existing material that is white with no textures.)
Delete any material/texture
Show the existing colour
Delete all other materials
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.
SketchUp
Size limitations
Bounding box: 500m x 500m x 500m (1640ft x 1640ft x 1640ft)
Polygons: Less than 4 million. To check this count refer to the steps below, using the number associated with Edges.
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 at [email protected]
Glass and Transparency
Glass layers must use translucent materials with over 80% transparency.
Opaque material settings will appear as solid objects.
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.
3ds Max
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 at [email protected]
Bounding box: 500m x 500m x 500m (1640ft x 1640ft x 1640ft). Refer to the diagram below displaying a bounding box.
Maximum objects: 100,000
Max: File > Summary Info
Polygons: Less than 4 million
While in 3ds Max, press 7 on the keyboard to open the viewport showing the polycount of the active view.
Textures, Materials and Lighting
Currently, we support colour & 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.
Glass and Transparency
Glass layers must use translucent materials with over 80% transparency.
Opaque material settings will appear as solid objects.
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.
