Overview
nanoCAD Plus 2026 by Nanosoft is a professional DWG-compatible CAD platform offering comprehensive 2D drafting, 3D solid/surface/mesh modeling, parametric design, and extensive API support at a budget-friendly price point. It provides native DWG file support, a familiar interface similar to AutoCAD, and advanced features including parametric constraints, dynamic blocks, and sheet set management — making it a compelling alternative for organizations seeking professional CAD capabilities without high licensing costs.
nanoCAD Plus has gained significant global traction as a cost-effective AutoCAD alternative with true .dwg native format support. Unlike free CAD options that compromise on functionality, nanoCAD Plus delivers professional-grade 2D drafting, robust 3D modeling, and comprehensive automation through LISP, COM, .NET, and C++ APIs. The software is available in three editions: Free (non-commercial), Plus (professional), and Pro (specialized architecture/BIM and mechanical modules).

Professional 2D Drafting
nanoCAD Plus delivers a complete 2D drafting environment with intelligent object snapping, advanced dimensioning, annotation scaling, hatch patterns, layer management with filters and groups, and all standard CAD drawing and modifying tools. The interface is designed to be immediately familiar to users transitioning from other DWG-based CAD platforms.
3D Modeling
The software supports wireframe, surface, solid, and mesh modeling with a full suite of 3D creation and editing tools. Users can create extrudes, revolves, sweeps, and lofts, perform Boolean operations, and visualize models with multiple viewport configurations and visual styles.
API and Automation
nanoCAD Plus supports LISP, COM, .NET, and C++ APIs, enabling users to run existing AutoCAD LISP routines, develop custom applications, and automate repetitive tasks. This broad API support ensures compatibility with a vast ecosystem of existing CAD automation tools.
Collaboration and Documentation
Advanced tools for collaboration include external references (XREF) with on-demand loading, sheet sets for multi-sheet document organization, batch plotting, PDF import/export with vector fidelity, raster image management, and markup and redlining capabilities.
