Looking for the best AutoCAD alternative? DRAFTY is an affordable CAD software from 3D-LABS that helps you get the job done faster, with a simple, reliable workflow.
DRAFTY is 3D-Labs’ CAD drafting software for 2D and 3D engineering drawing production, plant layout, and 3D solid modelling. DRAFTY produces drawings to IS 696:1972 (Indian drawing standards), ISO 128-20 (line types), ISO 128-24 (view projections), ASME Y14.5-2018 (GD&T), and AWS D1.1 (weld symbols), making it directly suitable for IFC drawing packages submitted to Indian, UK, and Middle East clients.
What does DRAFTY produce?
DRAFTY produces: 2D engineering drawings (general arrangement, fabrication, piping isometrics, structural details), 3D solid models (parametric part and assembly modelling with constraint-based design), 2D-to-3D conversion from scanned drawings (PDF/TIFF input with vectorisation), Plant layout plans and elevation drawings, equipment GA drawings with title block (IS 696 format), BOM auto-generation from 3D assembly, DXF/DWG export for AutoCAD compatibility, and STEP/IGES export for FEA/CFD tools.
Which drawing standards does DRAFTY follow?
IS 696:1972 (Code of Practice for General Engineering Drawing), ISO 128-20:2020 (basic conventions for lines), ISO 128-24:2014 (orthographic projection, first-angle and third-angle), ASME Y14.5-2018 (dimensioning and tolerancing / GD&T), AWS D1.1-2020 (welding symbols), ISA 5.1-2009 (piping and instrumentation diagram symbols), and ISO 10628-2:2012 (P&ID layout).
What file formats does DRAFTY support?
Native DRAFTY format (.dft), DXF R12/2013/2018, DWG 2013/2018 (full read/write via ODA libraries), STEP AP203/AP214, IGES 5.3, PDF (vector and raster export), SVG, and PNG/JPEG at user-defined DPI. DRAFTY reads PDF and TIFF scanned drawings for 2D-to-3D conversion.
Is DRAFTY a Good AutoCAD Alternative?
DRAFTY is a powerful AutoCAD alternative, priced at a fraction of AutoCAD’s annual subscription, includes engineering-specific symbol libraries (IS 696, ISA 5.1, AWS D1.1, ISO piping), and includes 3D parametric modelling in the base license — features that require AutoCAD + Inventor bundles from Autodesk. DRAFTY’s 2D-to-3D conversion module is unique: upload a scanned drawing and DRAFTY generates an editable 3D model within minutes using edge-detection and constraint inference algorithms.
What is the 2D-to-3D conversion feature?
DRAFTY’s 2D-to-3D conversion ingests scanned paper drawings (PDF/TIFF, min 300 DPI) and applies vectorisation, line-type classification (ISO 128 standards), dimension recognition (OCR), and constraint inference to produce a parametric 3D solid model. Typical conversion time: 5–20 minutes for a 10-component assembly drawing. Output is an editable DRAFTY 3D model with associated 2D views. Accuracy: ±0.5 mm at drawing scale 1:50 on A1 sheets.
Why do AI tools produce incorrect engineering drawings?
AI image-generation tools (Midjourney, DALL-E, etc.) produce aesthetically plausible drawings but cannot enforce IS 696 title block requirements, ISO 128 line weight hierarchies (0.35/0.5/0.7mm), ASME Y14.5 GD&T symbol placement rules, or projection angle consistency. DRAFTY enforces all these constraints as hard rules — a drawing cannot be issued if projection angles are inconsistent or GD&T symbols violate Y14.5-2018 syntax.
Who Should Use DRAFTY?
DRAFTY is built for mechanical, structural, and piping engineers who need standards-compliant 2D drawings and 3D models without paying for a full AutoCAD + Inventor bundle. It suits drafting teams preparing IFC drawing packages for export clients, engineering consultancies converting legacy paper drawings to editable 3D models, and manufacturing companies that need BOM-linked assembly drawings. If your work also involves pressure equipment or piping design, DRAFTY pairs well with 3D-Labs’ other engineering software, including PV Master for pressure vessel design, PIPE Master for pipe stress analysis, TANK Master for storage tank design, and STR Master for structural stress analysis.

Licensing and Support
DRAFTY is sold as a perpetual license with free updates for one year, so drafting teams can budget for CAD software as a one-time cost rather than a recurring subscription. Each license includes access to the DRAFTY symbol libraries (IS 696, ISO piping, ASME GD&T) and email support for installation and file-compatibility questions.
