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
> OK).
// 2. Add the SOLIDWORKS Simulation primary interop assembly as a reference
// (in the IDE, click Project > Add Reference > .NET >
// SolidWorks.Interop.cosworks > OK).
// 3. Ensure that the specified part exists.
// 4. Ensure that the specified material library exists.
// 5. Open the Immediate window.
//
// Postconditions:
// 1. Creates static study, frame.
// 2. Prints beam information to the Immediate window.
// 3. Applies Plain Carbon Steel material to all beams.
// 4. Calculates joints for all beams and displays a neutral axis for
// each beam.
// 5. Prints the pinball tolerance value and unit to the Immediate window.
// 6. Creates a mixed mesh and prints its type and state to the
// Immediate window.
//
// NOTES:
// * Creates beam elements by default for parts with structural members.
// * Because the part document is used elsewhere, do not save any changes.
