Get and Set Beams and Joints Example (VB.NET)

This example shows how to get and set beams and joints.

'--------------------------------------------------------------------------

' 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. Modify the path to solidworks materials.sldmat if needed.

' 4. Open the Immediate window.

' 5. Run the macro.

'

' Postconditions:

' 1. A static study, named frame, is created.

' 2. Beam information is printed to the Immediate window.

' 3. Plain Carbon Steel material is applied to all beams.

' 4. Joints are calculated for all beams, and

'    a neutral axis is shown for each beam. Pinball tolerance

'    value and unit are printed to the Immediate window.

' 5. Mesh is created, and type and state printed to Immediate window.

'

' NOTES:

' *  Beam elements are created by default for parts with

'    structural members.

' *  Because the part document is used with

'    a SOLIDWORKS Simulation online tutorial, do not save any

'    changes when closing the document.
