IGetMassProperties2 Method (ISldWorks)

Gets the mass properties from the specified document for the specified configuration.

.NET Syntax

Visual Basic (Declaration) 
Function IGetMassProperties2( _
   ByVal FilePathName As System.String, _
   ByVal ConfigurationName As System.String, _
   ByRef MPropsData As System.Double, _
   ByVal Accuracy As System.Integer _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As ISldWorks
Dim FilePathName As System.String
Dim ConfigurationName As System.String
Dim MPropsData As System.Double
Dim Accuracy As System.Integer
Dim value As System.Boolean
value = instance.IGetMassProperties2(FilePathName, ConfigurationName, MPropsData, Accuracy)
System.bool IGetMassProperties2( 
   System.string FilePathName,
   System.string ConfigurationName,
   ref System.double MPropsData,
   System.int Accuracy
System.bool IGetMassProperties2( 
&   System.String^ FilePathName,
&   System.String^ ConfigurationName,
&   System.double% MPropsData,
&   System.int Accuracy



Document path and file name


Name of configuration to use


Array of doubles

  • 0 = as is

  • 1 = default

  • 2 = maximum

Return Value

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

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

  • Remarks

    You can get the density of the current SOLIDWORKS part using ISldWorks::GetUserPreferenceDoubleValue and swMaterialPropertyDensity. If the density has not been explicitly set by the user, then SOLIDWORKS uses 1.0. You can also derive the density of the body from the following calculation:

    Density = ( Mass / Volume )

    Consistent with all other functions, this method returns metric units unless otherwise specified.

    If this IModelDoc2 object is an assembly, then any suppressed components are not included in the mass property analysis. See IComponent2::GetSuppression to determine the state of each of the assembly components.

    This method returns an empty array if mass properties are not calculated when saving the model. This is a system-level setting and is controlled by ISldworks::SetUserPreferenceToggle and swUpdateMassPropsDuringSave.

    NOTE: The calculated origin for the return values is based on the default coordinate systems of the IModelDoc2, not on the a selected coordinate system.
