-
A3DVector3dData m_sGravityCenter
Gravity center.
The value returned is in the unit of the entity (Modelfile unit if using A3DComputeModelFilePhysicalProperties on model file, Brep Unit (adjustable through an input scale) if using A3DComputePolyBrepPhysicalProperties or A3DComputePhysicalProperties).
-
A3DDouble m_dSurface
B-rep model surface area of resulting B-rep.
The value returned is in the unit of the entity (Modelfile unit if using A3DComputeModelFilePhysicalProperties on model file, Brep Unit (adjustable through an input scale) if using A3DComputePolyBrepPhysicalProperties or A3DComputePhysicalProperties).
-
A3DBool m_bVolumeComputed
When false, typically in case the B-rep is not a solid, indicates that the volumic properties were not computed.
-
A3DDouble m_dVolume
B-rep model volume of resulting B-rep.
The value returned is in the unit of the entity (Modelfile unit if using A3DComputeModelFilePhysicalProperties on model file, Brep Unit (adjustable through an input scale) if using A3DComputePolyBrepPhysicalProperties or A3DComputePhysicalProperties).
-
A3DVector3dData m_sSurfacicGravityCenter
Gravity center using the surfaces’ area as weight, rather than volume.
The value returned is in the unit of the entity (Modelfile unit if using A3DComputeModelFilePhysicalProperties on model file, Brep Unit (adjustable through an input scale) if using A3DComputePolyBrepPhysicalProperties or A3DComputePhysicalProperties).

11.2
-
A3DDouble m_adAreaMatrixOfInertia[9]
The inertia matrix calculated using the surface rather than the volume.
The value returned is in the unit of the entity (Modelfile unit if using A3DComputeModelFilePhysicalProperties on model file, Brep Unit (adjustable through an input scale) if using A3DComputePolyBrepPhysicalProperties or A3DComputePhysicalProperties).
- Version
11.2
-
A3DDouble m_adVolumeMatrixOfInertia[9]
The volumic inertia matrix.
The value returned is in the unit of the entity (Modelfile unit if using A3DComputeModelFilePhysicalProperties on model file, Brep Unit (adjustable through an input scale) if using A3DComputePolyBrepPhysicalProperties or A3DComputePhysicalProperties).
- Version
11.2
-
A3DBool m_bUseGeometryOnRiBRep
An input value which, if set to false, starts the calculations using RI tessellation (and internally computes a temporary tessellation if none is present).
If set to true, uses an A3DRiBrepModel’s geometry, and returns an error if it does not have any geometry. False by default.
- Version
11.2
-
A3DDouble m_dAccuracyLevel
An input value between 0.0 and 1.0 (default is 0.99).
Approaching 1.0 will make the calculation more accurate, but slower and less stable. The dependency is not linear. This can affect calculations on both tessellation and geometry, and when m_bUseGeometryOnRiBRep=false, will internally recompute tessellation on A3DRiBrepModels that contain geometry, without affecting input data.
