Apply Material to Bodies Example (C#)
This example shows how to apply user-defined and SolidWorks-defined
materials to different bodies.
//---------------------------------------------------------------------------
// 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 <SolidWorks_install_dir>\api\redist\CLR2 folder and
// select
SolidWorks.Interop.cosworks.dll).
// 3. Modify the path to solidworks
materials.sldmat if needed.
// 4. Run the macro.
//
// Postconditions:
// 1. Document opened.
// 2. Nonlinear study created.
// 3. Component count returned.
// 4. Materials applied to all components.
// 5. Expand the Parts folder in the Simulation Study
tree
// to
verify step 4.
//
// NOTE: Because this assembly document is used by a SolidWorks
// Simulation online tutorial, do not save any changes
when
// closing the document.
