LusoCAD 2026

Improved Features

Interface reconstruction

The LusoCAD interface has been rebuilt using the WPF framework and our own technologies to offer both visual refinement and technical power:

• Reconstructed Interface: Redesigned colour schemes and proportions, with more than 1,500 icons redesigned in SVG for clear, fluid visualisation at any scale. The theme's colours and refined display effects create an elegant, modern look.


• Optimised performance: Based on a new WPF architecture with optimised secondary development APIs and faster data handling. Full compatibility with ACAD libraries guarantees cost-free migration to existing .NET-based workflows.


• Usability optimisation: The recent documents area now displays icons and names, with support for up to 50 entries. Subpanels can be pinned, tabs and ribbon panels can be customised quickly with the right mouse button, and the text editor is now integrated into the ribbon to save screen space, along with other carefully designed interface improvements.

Improved performance

LusoCAD 2026 represents a big leap in overall performance compared to the 2025 version, guaranteeing a faster, more fluid and more responsive drawing experience in every respect:

The speed at which drawings are opened has improved by an average of more than 40%.
Common operations have improved over 20% (REGEN, MOVE, COPYCLIP, MIRROR, UNDO, REDO, etc.).

In addition to these general improvements, the main performance optimisations are highlighted below:

DIMCORD

The DIMCORD command now uses guidelines instead of polylines, so that when you move a block of text, its guideline automatically follows it, making labelling more intuitive. The updated "Parameters" dialogue box also allows you to adjust the scale and height of the text, and includes new Group and AutoChange options to offer greater flexibility and ease of use.



Batch Plot

It is now possible to preview the frame entries sequentially. Clicking on any entry starts the preview, while pressing the spacebar advances through the frames, with the active frame highlighted.



Batch Purge

The Batch Purge tool now supports the purging of registered applications, zero-length geometries, empty text objects and orphaned drawing data.



PDF import

The PDF import engine has been updated to the modern, actively maintained PDFium library, which increases import speed, improves the representation of raster images (transparency, sharpness, colour accuracy), improves text recognition and decoding (text on the same line is recognised as MText, each character being assigned a width factor based on the first character) and offers a clearer view of shading.



Data extraction

LusoCAD 2026 now supports saving the extraction configuration in .GXE files and reusing them as templates. You can also edit .GXE files to add or delete drawings, objects or properties. Any table linked to the same .GXE file will show the changes when those tables are updated.



 

New Features

Parametric restrictions (Phase 2)

While parametric constraints were introduced in LusoCAD 2025 with support for geometric constraints, LusoCAD 2026 extends this powerful functionality with dimensional constraints and the Parameter Manager. These improvements allow precise control over object sizes and proportions, providing tools to create, edit and organise dimensional constraint parameters, reference parameters and user variables, offering greater drawing flexibility.



DWG Compare

This function compares a specified drawing with the current drawing, using revision clouds to highlight the differences. It allows you to configure the comparison settings, import objects from the compared drawing and export/link the results in new snapshot drawings for future reference.



New 3D Modelling Workspace

Introduces a specific interface for *3D Modelling* alongside the *LusoCAD Classic* and *Draw 2D* workspaces. Shows only 3D-related toolbars, menus and palettes, hiding unnecessary interface elements to maximise the screen area dedicated to the modeller.



New TIFF plotting option (CCITT G4)

This plotter produces exclusively black-and-white output and significantly reduces file size while preserving the precision of lines, texts and dimensions.

Tool palette: importing XTP files

Tool palettes can now be customised by importing XTP files, allowing you to integrate text, tabs and block references from ACAD configuration sets. This speeds up workflows and ensures consistency between projects.



Barcode holder (Code 39)

Adds compatibility with *Code 39* barcodes for low-cost alphanumeric labelling, widely accepted in industrial environments.



 

LusoCAD Plugin × ARCHLine.XP

Integrated with ARCHLine.XP, this add-on allows the direct transfer of drawings in DWG or IFC format between LusoCAD and ARCHLine.XP, eliminating time-consuming import/export steps and offering an effortless CAD→BIM workflow.



 

Tools for Markers and Centrelines

It adds specific tools for placing centre marks and centre lines on circles and symmetrical geometry. These associative objects automatically update with the geometry, increasing drawing precision and simplifying annotation in mechanical or architectural projects. (Available in SP1).



 

Innovative features

Drawing Merge

It allows you to analyse, split and merge drawings in batches using external references, with customisable layout settings. It also includes visualisation of entity properties and export of the drawing list to a *.lst* file, improving project organisation.



 

Engineering Projection

The "ENGINEERINGVIEWMODE" variable allows you to change the bottom view from ACAD's default value to a real engineering projection, increasing the visual accuracy of technical drawings.



 

LusoCAD 2025

Improved Features

 

Improved performance

LusoCAD 2025 introduces an incremental recording mechanism, which increases the speed of SAVEAS by more than 30% and QSAVE by more than three times. File reading, viewing and software start-up are optimised, improving the average drawing opening speed by more than 25%. TRIM and EXTEND performance on complex drawings is improved by 69% and HATCH visualisation accuracy is also improved, eliminating excess lines in degraded and transparent shading, ensuring a more efficient workflow.

In addition, LusoCAD 2025 brings performance improvements in:

• Drawing opening speed


• Optimising 3D visualisation


• Multi-Line Text Optimisation


• Block Optimisation


• Selection improvements


• Layer management

​

Simplified quotations

To create different types of dimensioning, you no longer have to switch between different commands. Simply run the DIM command, hover the cursor over the objects to see a preview of the dimension, click to confirm and place the dimension. This speeds up the annotation process and improves efficiency.

Import and export of 3D models

Based on IFC import, you can now export IFC files and import RVT files with complete BIM data, and the STEP/IGES module is included in the LusoCAD 2025 installer, requiring no separate installation.

File and Layout tab bars

LusoCAD 2025's File and Layout tab bars have been updated with new features. By adding "New" and "List" buttons, you can now create, open and switch between drawings directly from the tab bar, making operations more convenient and efficient. In addition, indicators have been added for "Read Only" or "Modified" files, providing greater clarity of status.

Lasso selection

Loop selection allows you to create an irregularly shaped window or a cross-selection set, which is useful when selecting objects in complex drawings. Window selection has also been optimised with the Fence, Window Polygon and Cross Polygon options.

Undo command

Continuous zooming, scrolling and layer-related operations can be undone in a single step, speeding up the workflow and reducing repetitive actions.

Batch printing

LusoCAD 2025's batch printing function has been significantly improved based on user feedback to support a wider range of scenarios. There are 11 main updates covering the batch configuration specification, print configuration options, file configuration and processing options, ensuring a more efficient and flexible printing experience.

QR Code

The QRCODE command now supports the -QRCODE command line mode, making it easier to create QR codes using scripts or programmes.

PASTESPEC Command

After copying the data from an Excel spreadsheet to the clipboard, use the PASTESPEC command and select "Paste Link" to paste the Excel data as "DWG Entities". After insertion, you can modify the table. In addition, a data link will be created automatically and you can update this link using the DATALINKUPDATE command.

These restrictions manage the relationship between objects and allow automatic adjustments to other objects when changes are made, thus guaranteeing the accuracy and efficiency of the design.

Editing BIM data

BIM data can now be edited directly in LusoCAD 2025, providing greater efficiency in your design workflow.

Adaptation to 3D mouse devices

3Dconnexion's SpaceMouse and CadMouse are now compatible with LusoCAD 2025. You can manipulate 2D views and 3D perspectives using the joystick on the controller, change views and execute commands using the mouse shortcut keys, as well as customise the mouse button settings in the controller software for these devices.

Voice annotation

Using the Voice Manager panel, you can easily create, record, play back and manage voice annotations in LusoCAD 2025.

BREAKATPOINT command

The BREAKATPOINT command allows you to split the selected object into two objects at a specific point, without having to specify a second point to create an opening, as with the BREAK command.

DWG units

Different projects or application scenarios may require different units. For example, an architectural drawing might use metres, while another speciality drawing might use inches. In LusoCAD 2025, the recently added DWGUNITS command allows you to change the units of drawings to fulfil the drawing's standard size and annotation requirements and avoid errors due to the use of different units.

Application manager

Application Manager is a unified system for managing add-ons. Users can search, activate/deactivate and view details of modular applications within the Application Manager, achieving the most suitable service configuration with minimal use of resources.
