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.
//--------------------------------
