Description

The 3D model capabilities in MS are currently supporting GLTF in 3D model symbolizers. It is requested to provide also support for IFC 3D models:

• georeferenced if IFC v4 is used
• non-georeferenced for older IFC versions to be used instead of GLTF in model symbolizer

Proposal based on shared model by @ufficiosit

It is proposed here to create a new type of layer of type model to allow to include:

• Catalog to include an ifc as layer
• Workflow for import and visualize an ifc on map
• Identify workflow
• Panel settings with following options:
  • Visibility
  • General tab (title and description)
  • Custom tab to add possibility to change position of the center of the model
• [Optional] Add adjustment of the center interacting with the map (this need to include a review of the settings panel)

Notes:
We need to include the web-ifc library in MapStore (check license compatibility).

• Style panel will not be available for this type of layer. It is already defined within the model.
• This type of layer should be used for small IFC files. For large files it’s better to convert to 3D Tiles. we should consider to show a message to the user if the IFC file is too big to be rendered in MS (to evaluate during design)
