Add Force Example (VB.NET)
This example shows how to add a normal force of nonuniform distribution to a
static 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).
' 2. Add the SOLIDWORKS Simulation primary interop assembly as
' a reference (in the IDE's Project Explorer, right-click
' the project name, select Add Reference, click the Browse tab,
' navigate to the install_dir\api\redist\CLR2 folder and
' select SolidWorks.Interop.cosworks.dll).
' 3. Verify that the assembly exists.
'
' Postconditions:
' 1. Opens the assembly.
' 2. Creates a static study.
' 3. Adds Force-1 to the study.
' 4. To verify, examine the Simulation study tree.
'
' NOTE: Because this assembly is used elsewhere, do not save changes.
