Create Plots for a Static Study Example (VBA)

This example shows how to create plots of displacement, stress, and strain results in a static study.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Simulation as an add-in
'    (in SOLIDWORKS, click Tools > Add-ins > SOLIDWORKS Simulation).
' 2. Add the SOLIDWORKS Simulation type library as a reference
'    (in the IDE, click Tools > References > SOLIDWORKS
'    Simulation
version type library).
' 3. Open install_dir\Simulation\Examples\tutor1.sldprt.
'
' Postconditions:
' 1. Deletes all default static study plots from the model document.
' 2. Activates the Ready static study.
' 3. Meshes and runs the study.
' 4. Creates displacement, stress, and strain plots.
' 5. Gets the minimum and maximum values for the result plots.
' 6. Click OK to close any dialog boxes.
'
' NOTE: Because the model is used elsewhere, do not save changes.
