Creates a IMassProperty object.

.NET Syntax

Visual Basic (Declaration) 
Function CreateMassProperty() As MassProperty
Visual Basic (Usage) 
Dim instance As IModelDocExtension
Dim value As MassProperty
 
value = instance.CreateMassProperty()
C# 
MassProperty CreateMassProperty()
C++/CLI 
MassProperty^ CreateMassProperty();

Return Value

IMassProperty object

Example

Remarks

The IMassProperty object obtains mass property information about one or more solid bodies in the document from which the IMassProperty object is obtained.

 

Only use solid bodies for the mass property calculations. You can specify the coordinate system about which the moments is calculated using IMassProperty::SetCoordinateSystem. If you do not use IMassProperty::SetCoordinateSystem, then the documents origin is the coordinate system.

 

The results of the mass property calculations vary based on whether or not IMassProperty::AddBodies or IMassProperty::IAddBodies is used.  

 

If IMassProperty::AddBodies or IMassProperty::IAddBodies is...

Then...

Called and bodies are specified

These bodies can either be from a subset of the documents body list or from temporary bodies.  

NOTE: Each specified body should either come from the owning document or be a temporary body. If the body does not satisfy either case, then it is not used when calculating the mass properties.

Not called

Mass properties' calculations include all available bodies in the document.

  • Part. All of the solid bodies are included in the calculations.  

  • Assembly. All of the bodies in all of the components are used in the calculations.

 

If the document from which the IMassProperty object came is an assembly, then any body from any of the child components can be used. To obtain the body, call IComponent2::GetBodies2. Your application does not need to make a copy of the body or apply a transform to the body.

 

IModelDocExtension::CreateMassProperty gets the recalculated up-to-date values regardless of the IModelDocExtension::NeedsRebuild status.
