Performance improvement
Performance improvement
GstarCAD 2026 has deeply optimized the performance of common operations, and the performance indexes of core operations have been greatly improved, specifically including: multi-reference drawing opening, extending/trimming, clipping blocks and external references, block editing and previewing, mirroring, and creating blocks, and other operations.
Multi-Reference Drawing Opening Optimization
Optimized the performance of opening drawings containing a large number of external reference drawings, and solves the problem of lagging or timeout in the opening of some drawings.
Extending (Fence, Crossing) optimization
Extending performance in Fence and Crossing mode has been improved by more than 4.5 times on average compared to the previous version.
Trimming (Fence, Crossing) optimization
Trimming performance in Fence and Crossing mode has been improved by more than 1x on average compared to the previous version.
Clipped blocks and external references optimization
Drawings that include clipped blocks or external references have an average opening performance improvement of about 200% relative to pre-optimization, and a switching layout performance improvement of about 315%.
Block Editing Preview optimization
Improved the block preview speed of related commands (e.g. BEDIT/REFEDIT/INSERT etc. commands), solved the problem of oversized block preview lagging, and improved 6 times compared with the previous version.
Mirror
Mirror operation performance is improved by about 40% compared to the previous version.
Creating Block
No stuck and unresponsive issues when creating block objects containing a large number of multiple leaders; ~4x performance improvement for creating block objects containing a large number of large-coordinate entities; ~4x performance improvement for exploding inserted block objects.
Hatch
The point selection and hatch performance for complex drawings has been improved by over 30 times.
