• [Select Target]
  Select the range of the object to be exportedobjects to export.

  • All in Current Mode : Export Exports all objects that exist in the current Modemode.

  • Selected Objects Only : Export selected objects only.

• An entity is simply a nomenclature.

  • Example: CIM’s “Beam” is interchangeable with IFC’s “IfcBeam” entity.

• The following table represents IFC’s equivalent of CIM’s entity.

An IFC file is a neutral file format that enables compatibility and viewing with othre MIDAS products as well as other third-party softwares. The following is an example of a result from exporting and running a midas CIM model as an IFC file.

• • Exports only the selected objects.

• [Tessellation]

  • Tessellation is a setting that affects the precision of the geometry exported by the tessellation method.

    If you want to export more precise geometry by lowering the base angle value of Tessellation, you can change the setting in the direction of "Very Low → Low → Medium → High → Very High".

    However, the more precise the geometry, the larger the size of the IFC file, so be sure to apply the appropriate setting for your purposes.
