Create Aligned Linear and Ordinate Dimensions Example (C#)

This example shows how to create aligned linear and ordinate Dimensions for a closed PolyLine and Circles. A Leader and a geometric tolerance are also created.

//-------------------------------------------------------------
// 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.Forms.
// 5. Start DraftSight and open a document.
// 6. Click Start Debugging.
//
// Postconditions: 
// 1. A closed PolyLine and four Circles are constructed.
// 2. Aligned linear and ordinate Dimensions are created.
