Parameters

Density: Specifies the density to use in the physical property calculations.
Accuracy: Specifies the accuracy used when computing the physical properties.
BeadDensity: Specifies the density of to be applied to the weldbead bodies when computing the physical properties.
Volume: Returns the volume of the model.
Area: Returns the surface area of the model.
Mass: Returns the mass of the model.
CenterOfGravity: Returns three double values to indicate the x-, y-, and z-coordinates of the center of gravity of the model.
CenterOfVolume: Returns three double values to indicate the x-, y-, and z-coordinates of the center of volume of the model.
GlobalMomentsOfInteria: Returns six double values to indicate the Ixx, Iyy, Izz, Ixy, Ixz, and Iyz components of the global moments of inertia of the model.
PrincipalMomentsOfInteria: Returns three double values to indicate the lxx, lyy, and lzz components of the principal moments of inertia of the model.
PrincipalAxes: Returns nine double values to indicate the orientation of the principal axes of the model.
RadiiOfGyration: Returns three double values to indicate the radii of gyration of the model.
RelativeAccuracyAchieved: Returns a double value to indicate the actual accuracy achieved when calculating the physical properties. The accuracy parameter specifies the maximum accuracy, but, depending on the geometry of the model, the physical properties can be calculated more accurately.
Status: Returns an integer value that indicates the status of the physical properties of the model.

Remarks

Working from two inputs, density and accuracy, ComputePhysicalProperties calculates the physical properties of the referenced model. (It is assumed that there is one part per file.) This method acts on all solid geometry in the file and includes disjoint features. When no properties have previously been computed, ComputePhysicalProperties computes and returns the physical properties of the model. When properties have previously been computed but are out of date, ComputePhysicalProperties recomputes and then returns the physical properties of the model. When properties have previously been computed but are up to date, ComputePhysicalProperties returns the physical properties of the model without recalculating.
