GetMassProperties Method (IModelDocExtension)

Obsolete. Superseded by IModelDocExtension::GetMassProperties2.

.NET Syntax

Visual Basic (Declaration) 
Function GetMassProperties( _
   ByVal Accuracy As System.Integer, _
   ByRef Status As System.Integer _
) As System.Object
Visual Basic (Usage) 
Dim instance As IModelDocExtension
Dim Accuracy As System.Integer
Dim Status As System.Integer
Dim value As System.Object
 
value = instance.GetMassProperties(Accuracy, Status)
C# 
System.object GetMassProperties( 
   System.int Accuracy,
   out System.int Status
)
C++/CLI 
System.Object^ GetMassProperties( 
&   System.int Accuracy,
&   [Out] System.int Status
) 

Parameters

Accuracy
  • 0 = as is

  • 1 = default

  • 2 = maximum

Status

Status of the mass property results as defined in swMassPropertiesStatus_e

Return Value

Array of size 13 (see Remarks)

Remarks

The return value is a 0-based array of doubles as follows:

[ CenterOfMassX, CenterOfMassY, CenterOfMassZ, Volume, Area, Mass, MomXX, MomYY, MomZZ, MomXY, MomZX, MomYZ, Accuracy ]

You can use ISldWorks::GetUserPreferenceDoubleValue and swMaterialPropertyDensity to get the density of the SOLIDWORKS part. If the user did not explicitly set the density, then SOLIDWORKS uses a value of 1.0. You can also derive the density of the body by calculating:

Density = ( Mass / Volume )

This method returns metric units unless specified otherwise.

Then...

An assembly

  • SOLIDWORKS does not include any suppressed components in the mass property analysis. See IComponent2::GetSuppression to determine the state of each assembly component.

  • This method returns the moments of inertia (MOI) about the assembly center-of-gravity coordinate system aligned with the assembly axes.

A part

The calculated origin for the returned values are based on the default coordinate systems of the model document. They are not based on the selected coordinate system.

This method supports multibody parts.
