# Meshes

# Create Meshes For Configurations

The coordinate system within the Roomle ConfigurationScript is a left-handed cartesian coordinate system with +Z being the up vector and +Y the forward direction of the model. 1 model unit has to be equal to 1mm real world scale.

# Mesh Scale And Orientation

  • Left-handed coordinate system
  • Up vector: Z+
  • Forward direction: Y+
  • Units: One mesh unit represents 1mm real world scale

⚠️ Be aware of a possible scaling factor applied to the coordinates within your 3d application to display the desired real world units on screen!

This information may get lost when exporting to .obj resulting in an unexpected scaled mesh.

In doubt open an ASCII based .obj file in a texteditor and check if then coordinates have a reasonable size (eg. max. ~500-1000 units for a chair).

If you encounter issues with the size of your model, it is recommended to apply a scaling factor on export.

If the model is constructed "in Meters" (1 model unit = 1m) add a multiplication of 1000 on export.

A Model "in Centimeters" (1 model unit = 1cm) has to be upscaled by 10.

When working "in Millimeters" (1 model unit = 1mm) no scaling is needed on export.

# UV Scaling

Prepare the UV map to properly view the texture dimensions entered in the material settings.

  1. Create 20 x 20 cm real world scale plane 20cm x 20cm reference plane
  2. Apply the 5cm Grid Texture you can find here scale reference texture
  3. Map the same Grid to the Objects with the UVs that should be scaled texture on model
  4. Scale UVs so the grid sizes match on the objects and on the plane UV scaling off UV scaling fixed
  5. Now Scale the UVs by 200 so 1 UV tile = 1mm real world size UVs scaled x200
  6. Delete the reference plane removed plane
  7. Export the model like described above
  8. Zip the result and upload to Rubens Admin
  9. Enter the real world sizes for your textures
  10. The texture now maps exactly as expected finished model

# Meshes list

In the Meshes list, you can see all the meshes of one catalog. To see the list, go to Catalog management, select a catalog and click on Meshes. The overview can be displayed in a List view or a Grid view.

NOTE: Mesh management is not available for Level 1.

# Import or archive meshes

# Import meshes

To import a list of meshes, see Import meshes.

# Archive meshes

At the moment, it is not possible to archive a mesh.

# Manage existing meshes

To view an already existing mesh, select it in the Meshes overview and click on it.

On the details page of the mesh you can copy the External identifier and the AddExternalMesh command function and see a Preview of the mesh.
