IGetMassProperties Method (IModelDocExtension)

Obsolete. Superseded by IModelDocExtension::GetMassProperties2.

.NET Syntax

Visual Basic (Declaration) 
Function IGetMassProperties( _
   ByVal Accuracy As System.Integer, _
   ByRef Status As System.Integer _
) As System.Double
Visual Basic (Usage) 
Dim instance As IModelDocExtension
Dim Accuracy As System.Integer
Dim Status As System.Integer
Dim value As System.Double
 
value = instance.IGetMassProperties(Accuracy, Status)
C# 
System.double IGetMassProperties( 
   System.int Accuracy,
   out System.int Status
)
C++/CLI 
System.double IGetMassProperties( 
&   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

  • in-process, unmanaged C++: Pointer to an array of size 13; the last element is the accuracy at which returned mass properties are calculated (see Remarks)
  • VBA, VB.NET, C#, and C++/CLI: Not supported

    See In-process Methods for details about this type of method.

  • 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 explicitly specified otherwise.

    If this object is...

    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.
