| Name | Type | Description | 
|---|---|---|
| Type | P_SINGLEVALUE / IfcIdentifier | |
| MinBurnAngle | P_SINGLEVALUE / IfcPlaneAngleMeasure | |
| MaxBurnAngle | P_SINGLEVALUE / IfcPlaneAngleMeasure | |
| Bevel | P_SINGLEVALUE / IfcPlaneAngleMeasure | The bevel is nothing more than a kerf with a continuous opening angle between the cut and connecting material. Internally in the machine software the bevel is created mathematically by calculating the dihedral angle and subtracting the bevel from it. | 
| RootOpening | P_SINGLEVALUE / IfcLengthMeasure | |
| Shrinkage | P_SINGLEVALUE / IfcPositiveLengthMeasure |
