files, allowing users to import SketchUp models and flatten 3D views into 2D drafting projects. Advanced Drafting
: Features smart dimensions, hatch pattern editors, and the ability to input multiple unit types on-the-fly. Performance & Usability
DoubleCAD XT 6 is a free, professional-grade 2D CAD software developed by IMSI Design. Known for its intuitive interface and strong compatibility with AutoCAD DWG files, DoubleCAD XT 6 offers powerful drafting tools, 3D printing preparation features, and advanced editing capabilities — making it a popular choice for architects, engineers, and hobbyists seeking a cost-effective alternative to paid CAD solutions.
If you provide a concrete use case (e.g., “I want to auto-number blocks in a drawing”), I can give you a step-by-step implementation.
DoubleCAD XT 6 is a free, professional-grade 2D CAD application designed as a high-compatibility alternative to AutoCAD LT. While it is an older software—with the original developer's website often appearing broken—it remains a "hidden gem" for users needing a robust, no-cost drafting tool that handles industry-standard file formats. Top Performance & Features
AutoCAD Familiarity: The interface is heavily inspired by AutoCAD 2008, featuring a similar menu bar, drawing tools, and even the same command names. This allows users familiar with AutoCAD to migrate with almost no learning curve.
Superior File Compatibility: Unlike many free tools, it can open and save .DWG and .DXF files (from R14 up to 2012 versions) and uniquely supports importing Google SketchUp (.SKP) files with layers and blocks intact.
Productivity Tools: It includes features not found in AutoCAD LT, such as "self-healing" walls, a Power Stretch tool, and an intelligent cursor that provides visual feedback directly at the data entry point. doublecad xt 6
Commercial Use: It is explicitly free for both personal and unlimited commercial use, making it a legal and cost-effective choice for small engineering or architectural firms. Drawbacks to Consider
2D Only: While it can open 3D files, you cannot rotate or edit them effectively; it is strictly a 2D drafting and detailing program.
Obtaining a License: The official download page is often inactive. Users frequently have to contact TurboCAD support via their chat feature to request a free license key and download link.
Occasional Bugs: Some users report that the software can be "buggy," with occasional crashes and difficulties using snapping tools.
No LISP Support: It does not support LISP routines or other common AutoCAD automation methods, though it does have its own SDK for custom tool creation. Verdict
DoubleCAD XT 6 is a powerful, "wallet-friendly" alternative for those who need AutoCAD-like functionality without the subscription fee. It is especially useful as a high-powered file viewer and editor for SketchUp and older DWG files.
What it is: DoubleCAD XT 6 is a CAD (computer-aided design) program compatible with DWG/DXF files, aimed at 2D drafting and basic 3D operations; it’s often positioned as a lower-cost alternative to AutoCAD for Windows users.

DoubleCAD XT 6 is a free, high-performance 2D CAD application developed by IMSI Design (the makers of TurboCAD) as a powerful alternative to AutoCAD LT
. While it is no longer actively marketed, it remains a robust "work-alike" for drafting and detailing, offering full commercial usage rights for free. Key Features and Capabilities Drafting and Detailing
: Optimized for 2.5D CAD, it includes standard tools like offset, scale, trim, and chamfer. File Interoperability
: Excellent support for industry-standard formats, including reading and writing (up to R14), (Google SketchUp). Intelligent Architecture Tools
: Features "self-healing," ACA-compatible walls and self-aligning blocks that retain their properties even when exported back to AutoCAD. User Interface
: Closely mirrors the "classic" AutoCAD 2008 interface, including a functional command line and standard shortcuts, making it easy for long-time CAD users to transition. Unique Features DoubleCAD XT 6 is a powerful, free 2D
: Includes Bezier curves, transparent fills, and a brush editor, which are often missing from basic 2D CAD packages. Common Use Cases AutoCAD Companion
: Use it as a secondary seat to view, edit, or mark up drawings without paying for additional licenses. SketchUp Workflow
: It is specifically designed to be a companion for SketchUp, allowing users to flatten 3D views into 2D drafting sheets automatically. Professional 2D Drafting
: Suitable for designing floor plans, mechanical parts, and architectural details for commercial projects. SketchUcation Known Limitations and Issues Availability
: The official download site is frequently reported as broken or difficult to navigate; users often need to request a license key through the TurboCAD support page
: Version 5 was known to be buggy and prone to crashes, though users report Version 6 is more stable and includes features like tab-based line length and angle settings. 3D Constraints
: While it can open 3D files, users cannot rotate or manipulate them in a 3D workspace, as it is strictly focused on 2D output. comparison guide

DoubleCAD XT 6 is a free, professional-grade 2D CAD application developed by IMSI Design that serves as a powerful alternative to AutoCAD LT . It is widely recognized for its high compatibility with .dwg files and its specialized tools for architectural and mechanical drafting . Key Features and Capabilities DoubleCAD - Download
DoubleCAD XT v6 is a discontinued (but still used) 2D/3D CAD software from IMSI Design, based on the IntelliCAD engine.
Since it's not open source and its API is limited compared to AutoCAD, feature development typically involves:
Unlike strictly 2D tools, DoubleCAD XT 6 allows you to draw in 2D and then extrude, sweep, or loft those profiles into 3D solids. It utilizes the ACIS® modeling kernel (the same engine found in high-end software like SolidWorks and AutoCAD), ensuring precise geometry for boolean operations (union, subtract, intersect).
