Create and Change EntityGroups Example (C#)

This example shows how to create and change EntityGroups.

//--------------------------------------------------------------
// 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 and open a document.
// 6. Start debugging the project.
//
// Postconditions: 
// 1. Inserts entities, two lines and two circles, in the drawing.
// 2. Creates two EntityGroups:
//    * SampleGroup1 contains two lines, line1 and line2.
//    * SampleGroup2 contains two circles, circle1 and circle2.
// 3. Changes the color of the lines from white to red.
// 4. Removes an entity, circle1, from SampleGroup2.
// 5. Adds an entity, circle2, to SampleGroup1.
// 6. Reorders SampleGroup1.
// 7. Explodes SampleGroup2, which removes the definition
//    from the drawing; however, circle1 remains as an entity
//    in the drawing.
// 8. Renames SampleGroup1 and changes its description.
//
// NOTE: Execution of the macro stops several times. Follow the
// instructions in the macro each time execution stops.
