Extruding Entities Example (C#)
This example shows how to extrude 3D entities.
//--------------------------------------------------------------
// Preconditions:
// 1. Create a C# Windows console project.
// 2. Copy and paste this example into the C# IDE.
// 3. Add a reference to:
// install_dir\APISDK\tlb\DraftSight.Interop.dsAutomation.dll
// 4. Add references to System and System.Windows.Forms.
// 5. Start DraftSight.
// 6. Press F5 to debug the project.
//
// Postconditions:
// 1. Extrudes 2D entities to both 3D
solids and 3D surfaces by
// both heights and paths.
// 2. Inspect the graphics area.
