The Industry Foundation Classes (IFC)[1] is a CAD data exchange data schema intended for description of architectural, building and construction industry data.
IFC (*.ifc) files can be imported into the Tygron Platform.
Version IFC4 is supported, earlier versions (e.g. IFC2x3) might contain errors.
Supported Representations
The following representations[2] are supported:
- BoundingBox
- SolidModel
- ExtrudedAreaSolid (using Profile Definitions)
- FactedBreb with FaceBounds: EdgeLoop or PolyLoop)
- MappedItem
- Curve:
- Polyline
- IndexPolyCurve
- TessellatedFaseSet:
- TriangulatedFaceSet
- PolygonalFaceSet
Profile Definitions
The following profile definitions[3] are currently supported:
- ArbitraryClosedProfile (outer and inner curves)
- ParameterizedProfiles:
- CircleProfile (incl. hollow)
- CShapeProfile (excl. fillet)
- IShapeProfile (excl. fillet)
- RectangleProfile (incl. hollow)
Styles
By default, IFC features will be colored in Light Gray. The following styles are supported that can override this color:
- Surface styles: IfcSurfaceStyleShading; with style that has a SurfaceColour defined.
- FillAreaStyle: IfcColourRgb and IfcPredefinedColour; both reference colors directly.
Textures are not yet supported.
