Powerful Performance

With our advanced technology and optimized algorithms, GstarCAD guarantees faster processing speeds. Our efficient multi-core processing ensures smoother handling of complex drawings, reducing lag and enhancing user experience. Additionally, Hardware Acceleration boosts your computer's graphics capabilities, providing better performance and smoother visuals.

Better than ever

GstarCAD 2025 elevates performance to a new level with Hardware Acceleration and other improvements, significantly enhancing the design experience. Exciting new features include Parametric Constraints, BIM Data Editing, and Voice Annotation, etc. Moreover, compatibility has been expanded with the addition of Python support, empowering more robust customization and automation！

Hardware Acceleration
GstarCAD 2025 now includes Hardware Acceleration, which uses the powerful graphics processing capabilities of the GPU to help the CPU handle tasks more efficiently. This update greatly improves the quality of graphic display and speeds up your work, enhancing the overall performance of the software.

Parametric Constraints
GstarCAD 2025 introduces Parametric Constraints, focusing exclusively on geometric constraints this year. Geometric constraints manage how objects relate to others, enabling automatic adjustments to other objects when changes are made, ensuring design precision and efficiency.

API (Python)
In addition to the continuous improvement of integrity and compatibility of GRX, .NET and LISP interfaces, GstarCAD 2025 now supports Python, offering over 790 commonly-used python interfaces, thus empowering more robust customization and automation.
