What's new in GstarCAD 2025
GstarCAD 2025 introduces an incremental save mechanism, optimizes the reading and display of graphics, and enhances the trimming and extending algorithms, resulting in significant performance improvements in opening, saving, and trimming and extending operations. The compatibility and completeness of GRX, .NET, and LSP are continuously enhanced, and Python is supported to expand the functionality of the GstarCAD platform software, reducing the cost and learning curve for secondary development.
GstarCAD 2025 has added important functional modules such as parametric constraints, application manager, and hardware acceleration. It has also improved features like file/layout tab bars, selection functionality, and batch printing, enhancing user operation and design efficiency, and improving user experience.
Performance Improvements
GstarCAD 2025 introduces an incremental save mechanism, significantly enhancing the performance of SAVEAS and QSAVE. The performance of SAVEAS has improved by over 30%, and QSAVE by more than five times.
Optimizations have been made for the reading and display of graphics such as hatches, 3D objects, TTF text, proxy objects, splines, and circles. Additionally, processes like CUI interface, layer panel initialization, and tool palette initialization have been optimized, resulting in an average improvement of over 30% in opening drawings, with some drawings seeing more than a threefold improvement in performance.
Furthermore, optimizations have been made to the logic and algorithms of entity traversal, graphic order processing, and graphic intersection during trimming, leading to an average improvement of 64% in the performance of trimming and extending in complex drawings, with some seeing an improvement of over ten times. The issue of lag in trimming and extending complex drawings has been essentially resolved.
The display effect of hatches has been improved, addressing the issue of displaying unnecessary lines with gradient and transparent fills.
Secondary Development Interface Enhancement and Expansion
The new version of GstarCAD continues to enhance the completeness and compatibility of GRX, .NET, and LSP, allowing secondary development programs to run normally after being ported, further reducing the cost of secondary development porting.
Support is provided for users to expand the functionality of the GstarCAD platform software using Python on Windows systems, with over 790 common Python interfaces supported, covering various daily use scenarios for users. By calling GRX interfaces through script-style statements, cross-platform development is supported, and the learning cost for new developers can be reduced.
New Features
1、Parametric Constraints
Parametric constraints (geometric constraints) are a technique for associating and restricting two-dimensional geometric figures to control that objects satisfy one or more geometric relationships. There are twelve types of geometric constraints corresponding to twelve geometric relationships: Coincident, Collinear, Concentric, Fixed, Parallel, Perpendicular, Horizontal, Vertical, Tangent, Symmetric, Smooth, and Equal.
2、DIM
To enhance drawing efficiency, we have optimized the DIM annotation operation. Now, you can create multiple annotations and annotation types using the DIM command, supporting linear, coordinate, angular, radius, diameter, arc length, and miter annotations. There is no need to frequently switch between different annotation commands, simplifying the process and accelerating drawing speed.
3、Hardware Acceleration
A new hardware acceleration feature has been added to GstarCAD 2025, utilizing the GPU, which is adept at handling images, to assist the CPU in solving problems, thereby improving the display of graphics and work efficiency, and enhancing overall performance. With hardware acceleration enabled using the GPU, you can also achieve real-time display effects of higher quality and efficiency compared to the CPU, and has a better highlight effect.
4、3D Mouse Device Adaptation
GstarCAD 2025 supports 3dconnexion's SpaceMouse and CADMouse, including controller stick operations for view manipulation, shortcut keys for quick command invocation, shortcut keys for view switching, and custom button configurations for the device within the driver.
5、VOICEMANAGER
Supports users adding voice annotations to drawings. Through an integrated panel, users can easily create, record, play, and manage voice annotations, with a maximum voice duration of sixty seconds.
6、3D Model File Import and Export
The new version of GstarCAD 2025 supports exporting IFC files, importing RVT format, and BIM editing features.
7、BREAKATPOINT
The new version of GstarCAD 2025 supports breaking the selected object into two objects at a specified point, facilitating users to break lines at a single point through command input, script writing, and programming.
8、DWGUNITS
The new version of GstarCAD 2025 supports the DWGUNITS command to modify the drawing units, enabling users to ensure that the dimensions and annotations of their drawings comply with standardized requirements, preventing errors caused by different size units, and increasing the readability of the drawings.
9、File Tab Bar and Layout Tab Bar Improvements
The file tab bar in the GstarCAD 2025 version has been enhanced with new "Create" and "List" buttons. Creating, opening, and switching drawings can all be accomplished directly from the file tab bar, making the process more convenient and efficient. A lock or modification indicator has been added to provide a clearer display of the file's status. The appearance and display method have also been modified to occupy less space. The layout tab bar has been updated to match the style of the file tab bar and includes an additional "List" button.
10、Selection Function Improvements
The new version of GstarCAD 2025 supports lasso selection, allowing users to freely draw different selection areas to choose entities, with support for switching selection modes during box selection. The PICKAUTO system variable has been optimized for compatibility with AutoCAD. The command execution now supports cyclic selection, which allows users to filter and select the graphic objects they need to operate on among overlapping objects.
11、UNDO Function Improvements
The new version of GstarCAD 2025 supports the combination of panning and zooming mouse operations and commands, supports layer merging, and is compatible with the UNDOCTL system variable, consistent with AutoCAD.
12、Batch Printing Function Improvements
The batch printing function in the new version of GstarCAD 2025 has been comprehensively improved based on user feedback and is now applicable to more scenarios. The main improvements include graphic selection and filtering, printing settings and options, file settings, and processing options.
13、QRCODE Function Improvements
The new version of GstarCAD 2025 QRCODE command supports command-line mode -QRCODE, facilitating users to generate QR codes through scripts or programs.
14、CAD Table to Excel Function Improvements
The new version of GstarCAD 2025 has added support for WPS to the table to Excel function. Table objects in CAD can now be exported not only to Excel spreadsheets but also to WPS spreadsheets.
15、Application Manager
A unified plugin management system provides a set of unified plugin extension standards for internal module developers, third-party application developers, and platform custom development manufacturers to meet the needs of the GCAD platform for stability, cross-platform compatibility, ease of expansion, and ease of deployment. Users can search for modular applications in the application manager, and perform operations such as enabling/disabling and viewing details.
