Add Nonuniform Force Distribution Example (VBA)

This example shows how to add a force of nonuniform distribution to a study.

NOTE: To get persistent reference identifiers (PIDs) for model selections, you can use pidcollector.exe or IModelDocExtension::GetPersistReference3.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Simulation as an add-in (in SOLIDWORKS, click
'    Tools > Add-ins > SOLIDWORKS Simulation > OK).
' 2. Add the SOLIDWORKS Simulation type library as a reference (in the IDE,
'    click Tools > References > SOLIDWORKS Simulation version type library).
' 3. Verify that the specified assembly exists.
' 4. Open the Immediate window.
'
' Postconditions:
' 1. Opens the assembly.
' 2. Inserts a coordinate system.
' 3. Gets the Ready study.
' 4. Adds a force of nonuniform distribution to Ready.
' 5. Inspect the Immediate window.
'
' NOTE: Because this assembly is used elsewhere, do not save changes.
