Create Plots and Get Values Example (VBA)

This example shows how to get the translational displacement and velocity values for a selected face and how to plot these values.

'---------------------------------------------------------------------
' Preconditions:
' 1. Start SOLIDWORKS Premium, which includes SOLIDWORKS Motion.
' 2. In SOLIDWORKS:
'    a. Start the SOLIDWORKS Motion Study add-in (click Tools > 
'       Add-Ins > SOLIDWORKS Motion).
'    b. Open public_documents\tutorial\motionstudies\valve_cam.sldasm.
'    c. Click the 1200 Motion Study tab in the lower-left corner of
'       the MotionManager.
'    d. Select Motion Analysis in the Type of Study list at the
'       upper-left corner of the MotionManager.
' 3. In the IDE:
'    a. Add a reference to the SOLIDWORKS MotionStudy type library.
'    b. Open the Immediate window.
'
' Postconditions:
' 1. Selects two faces.
' 2. Calculates the motion analysis for the two selected faces.
' 3. Gets the translational displacement and translational velocity
'    values for the first selected face.
' 4. Creates plots of the translational displacement and translational
'    velocity.
' 5. Prints the names of the plot features to the Immediate window.
'
' NOTE: Because the assembly is used elsewhere, do not save changes.
