This example shows how to construct an Arc.
//-------------------------------------------------------------- // 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: A message box pops up when an Arc is // constructed in the drawing document. //---------------------------------------------------------------- using DraftSight.Interop.dsAutomation; using System; using System.Runtime.InteropServices; using System.Windows.Forms;
