Get and Set Beams and Joints Example (C#)

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 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. Mixed 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.
