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: Specified document exists.


// Postconditions: The material ABS PC from the

// SolidWorks Material database is applied to all

// bodies in the open part document.


// NOTE: Because the part document is used elsewhere,

// do not save any changes when closing it.
