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. autocad plugin entwicklung
