Author: [Author Name] Affiliation: [University/Company Name] Date: April 14, 2026 Abstract AutoCAD remains a dominant platform for computer-aided design (CAD) across architecture, engineering, and construction (AEC). However, its native interface often lacks domain-specific automation, necessitating custom plugin development—termed Plugin Entwicklung in German engineering contexts. This paper presents a comprehensive methodology for designing, implementing, and deploying AutoCAD plugins using the .NET framework (C#) and the AutoCAD .NET API. We compare this approach with legacy alternatives (AutoLISP, VBA) and evaluate performance metrics for three case studies: automated layer management, parametric part generator, and batch plot exporter. Our results demonstrate that .NET-based plugins reduce repetitive task time by up to 87% while maintaining stability across AutoCAD versions. We conclude with best practices for error handling, cross-version compatibility, and deployment.
Speedup factors are high due to elimination of manual selection and command repetition. 7. Cross-Version Compatibility and Deployment 7.1 Managing AutoCAD Version Differences Use conditional compilation symbols:
[CommandMethod("DRAWDOOR")] public static void DrawDoor()
BlockTable bt = tr.GetObject(db.BlockTableId, OpenMode.ForRead) as BlockTable; BlockTableRecord btr = tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite) as BlockTableRecord; // ... create entities tr.Commit();
var doc = Application.DocumentManager.MdiActiveDocument; var db = doc.Database; var ed = doc.Editor; try
