Set Material Example (C#)

This example shows how to get the names of the material schema, material databases, and bodies in a part document. This example also shows how to apply a SOLIDWORKS Material to all of the bodies in a part document.

// Preconditions:
// 1. Verify that the specified document exists.
// 2. Open the Immediate window.
// Postconditions:
// 1. Opens the specified part document.
// 2. Applies the material ABS PC (polycarbonate plastic)
//    from the SOLIDWORKS Material database to all
//    bodies in the part.
// 3. To verify, examine:
//    * DisplayManager tab
//    * graphics area
//    * Immediate window
// NOTE: Because the part document is used elsewhere,
// do not save changes.
