General requirements for IFC models for uploading to the Bimar System

These requirements must be met so that models can be loaded into the Bimar system without errors.

  • The model should contain only the elements that you want to load
  • The model ** must** contain IFC2x3 or IFC4 markup. The remaining versions are without guarantees of proper operation
  • The model must contain all the necessary information that you need to download:
    • Length, Width, Height (if possible, otherwise the BoundingBox will be taken)
    • Material (as an attribute or via a materialayer)
  • Weight (if not, you can use a weight mapping)
  • Item brand
  • Item type
  • IFC encoding must be UTF-8 without BOM
  • All Cyrillic characters ** must** be formatted with Escape sequences, as shown in the figure:

  • The IFC file ** must** contain data related to the production cycle. For example, if you ship metal according to a project, then you can’t use only IfcColumn, IfcBeam, they need to be combined in IfcElementAssembly and analyzed using it.

  • The model ** must not** contain excessive debris in the form of fittings, surface treatments, welding, bolts. They will not be analyzed, but they load the model.
  • The model must be located at the correct base point of the project
  • The model should not store duplicate geometries or imaginary objects, such as in the examples:
