Specify IGES Levels and Values, Then Import IGES File Example (C#)

This example shows how to:

  • specify levels and values for importing IGES data.
  • import an IGES file.
//------------------------------------------------
// Preconditions: Substitute the path and name
// of your IGES file where noted in the code.
//
// Postconditions: 
// 1. Creates a folder named Layer 25.
// 2. Imports the specified IGES file into SOLIDWORKS
//    and moves the imported IGES features to Layer 25.
// 3. To verify, examine the graphics area and
//    FeatureManager design tree.
