What’s New
In GstarCAD 2026

Interface Reconstruction Improvement
11
GstarCAD interface has been reconstructed using the WPF framework and our own technologies to deliver both visual polish and technical power:
Visual Refresh: Redesigned color schemes and proportions, with 1500+ icons redrawn in SVG for clear and smooth display at any scale. Refined theme colors and display effects create a sleek, modern look.
Technical Upgrade: Built on a new WPF architecture with optimized secondary development interfaces and faster data handling. Full compatibility with ACAD libraries ensures zero-cost migration for existing .NET-based workflows.
Usability Optimization: Recent Documents now display icons and names, with support for up to 50 entries. Subpanels can be pinned, ribbon tabs and panels can be quickly customized via right-click, and the text editor is now embedded in the ribbon to save screen space, along with other thoughtful UI improvements.

Performance Improvement
12
GstarCAD 2026 delivers a major leap in overall performance compared to the 2025 version,
ensuring a faster, smoother, and more responsive design experience across the board:
Drawing opening speed improved by over 40% on average
Common operations improved by over 20% (REGEN, MOVE, COPYCLIP, MIRROR, UNDO, REDO, etc.) 
In addition to these overall gains, key performance enhancements are listed here:
Feature/Operation
Performance Gain vs. GstarCAD 2025
  Multi-reference drawing opening (without clipping)
  Previously lag-prone drawings now open in under 1 minute
  EXTEND (Fence/Crossing)
  11× faster
  TRIM (Fence/Crossing)
  2× faster
  Clipped blocks & Xrefs
  2.9× faster opening
  4.2× faster layout switching
  Block editing preview (BEDIT/REFEDIT/INSERT)
  7× faster
  MIRROR operation
  1.4× faster
  Block creation/explosion
  5× faster block creation with high-coordinate entities
  5× faster explosion of inserted blocks
  Freeze eliminated for multileader-heavy blocks
  Hatch (pick-point on complex drawings)
  30× faster

DIMCORD Improvement
13
The DIMCORD command now features leader lines instead of polylines, so moving a text block automatically carries its leader with it, making label placement more intuitive. 
The updated “Parameters” dialog also lets you adjust scale and text height, and includes new Group and Auto Switch options for greater flexibility and ease of use.

Batch Plot Improvement
14
Frame records can now be previewed sequentially. Clicking any record initiates the preview, while pressing the spacebar advances through frames with the active frame highlighted. 

Batch Purge Improvement
15
The Batch Purge tool now supports cleaning up registered applications, zero-length geometries, empty text objects, and orphaned drawing data.

PDF Import Improvement
16
The PDF import engine has been upgraded to the modern, actively maintained PDFium library—boosting import speed, enhancing raster image rendering (transparency, clarity, color accuracy), improving text recognition and decoding (same-line text is recognized as MText, with each character assigned a width factor based on the first character), and delivering crisper hatch displays.

Data Extraction Improvement
17
GstarCAD 2026 now supports saving extraction settings in .GXE files, and reusing them as templates. You can also edit .GXE files to add or remove drawings, objects, or properties. Any tables linked to the same .GXE file will display the changes when those tables are updated.

Parametric Constraints (Phase 2) New
18
While Parametric Constraints were first introduced in GstarCAD 2025 with support for Geometric Constraints, GstarCAD 2026 expands this powerful feature with Dimensional Constraints and Parameters Manager. These enhancements enable precise control over object sizes and proportions, and provide tools to create, edit, and organize dimensional constraint parameters, reference parameters, and user variables for greater design flexibility.

DWG Compare New
19
This feature compares a specified drawing with the current drawing, using revision clouds to highlight the differences. It allows users to configure comparison settings, import objects from the compared drawing, and export and bind the results into new snapshot drawings for future reference.

3D Modeling Workspace New
20
Introduces a dedicated “3D Modeling” interface alongside the GstarCAD Classic and 2D Drafting workspaces. It displays only 3D-related toolbars, menus, and palettes—hiding unnecessary UI elements to maximize your modeling screen space.

Plot: "TIFF Version 6 (CCITT G4 2D Compression)" 
Plotter Support New
21
This plotter supports only black-and-white output and greatly reduces drawing file sizes while preserving the accuracy of lines, text, and dimensions.

Tool Palette: XTP File Import New
22
Tool palettes can now be customized by importing XTP files, allowing the integration of text, separators, and block references from ACAD configuration sets. This streamlines workflows and ensures consistency across projects.

Barcode: Code 39 Support New
23
Adds support for Code 39 barcodes for low-cost, alphanumeric labeling with broad industrial compatibility.

GstarCAD × ARCHLine.XP Plugin New
24
Integrated with ARCHLine.XP, this plugin enables direct transfer of drawings in DWG or IFC format between GstarCAD and ARCHLine.XP, eliminating tedious import/export steps and offering an effortless CAD-to-BIM workflow.

Center Mark & Centerline New
25
Adds dedicated tools for placing center marks and centerlines on circles and symmetrical geometry. These associative objects update automatically with the geometry, enhancing drawing precision and simplifying annotation in mechanical or architectural layouts. (Available in SP1)

Drawing Merge Innovative
26
The Drawing Merge feature enables batch analysis, splitting, and merging of drawings through Xrefs, offering customizable layout settings. Additional capabilities include viewing entity properties and exporting the drawing list to a .lst file for enhanced project organization.

Engineering Projection Innovative
27
The ENGINEERINGVIEWMODE system variable enables switching the bottom view from ACAD’s default to a true engineering projection, enhancing visual accuracy in technical drawings.

GstarCAD for Mac New
28
In addition to Windows and Linux, GstarCAD is now available for macOS —fully compatible with Apple M-series and optimized for arm64 architecture.
The Mac version offers a familiar interface and consistent user experience,supporting over 790 features and covering about 85% of the Windows version's full functionality.
Enjoy fast performance, seamless drafting, and reliable productivity — now on Mac.

GstarCAD Point Cloud 2026 New
29
Integrated with Undet Point Cloud plugin, this powerful solution offers a full suite of tools that allow you to seamlessly import and manage point cloud data directly in GstarCAD. With GstarCAD's comprehensive drafting features, you can create accurate 2D and 3D drawings from Point Cloud with great efficiency.
You can create point cloud projects seamlessly with data from any laser scanner or drone in Undet Indexer, then open, transform, and manage them directly in GstarCAD (Supported formats: *.E57, *.FLS, *.RCP/RCS, *.PTX, *.ZFS,*.LAS, *.LAZ, *.PTS, *.PLY, *.DP, *.FPR, *.LSPROJ, *.FWS, *.CL3, *.CLR, *.RSP, ASCII / NEZ (X,Y,Z/i/RGB) and custom ASCII / TXT file format import). GstarCAD Point Cloud also offers interactive editing and visualization capabilities, allowing users to view, analyze and navigate your digital data as a panoramic view in Undet Browser, speeding up the creation process.
