[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.
