Best CAD Software in 2026: Free and Paid Options for Engineering, Drafting and 3D Printing

The best CAD software depends on what you are making. FreeCAD and Autodesk Fusion cover parametric mechanical design, SolidWorks and Onshape are the professional engineering options, LibreCAD and AutoCAD handle 2D drafting, and Tinkercad, OpenSCAD and Blender cover simple modelling and 3D printing.

The 12 picks below are grouped by use. The live table shows licence, self-hosting and pricing data, so you can see at a glance which tools are open source or have a free tier. Platform support is stated only where the vendor's own page gives it.

How we picked the best CAD software

Enlisted's 3D and CAD category mixes real CAD programs with renderers, slicers and viewers, so the first step was sorting out which tools do the job a CAD searcher wants: designing a part, drawing a plan or modelling an object to print. Open-source picks needed recent GitHub activity, and licences are quoted as listed. For commercial tools, the catalogue records pricing pages and free tiers, and some vendor pages could not be read in full, so confirm current editions and platforms on the vendor's site before you buy. Nothing here was scored on modelling quality. See how Enlisted ranks tools.

It helps to know the three jobs people mean by CAD. Parametric 3D CAD builds parts from sketches and dimensions you can edit later. 2D drafting produces technical drawings. 3D modelling for printing creates a mesh you send to a slicer. Most tools do one of these well, so pick by job.

Best for parametric and mechanical design

Parametric CAD keeps a history of how a part was built, so changing one dimension updates the whole model. These four are the main choices for mechanical and product design.

1. FreeCAD: best free and open-source parametric CAD

FreeCAD is a free, open-source parametric 3D modeler for designing real-life objects of any size, with versions for Windows, Mac and Linux. You sketch constrained 2D shapes, build 3D parts from them, and generate production drawings from the model. Its site lists support for formats such as STEP, IGES, STL, DXF and IFC, along with workbenches for finite element analysis, CAM and BIM, and a Python API for scripting.

It is released under LGPL-2.1, and the project is funded by optional donations and sponsorship rather than licence fees. Browse the FreeCAD page for release activity.

• Best for: hobbyists, students and engineers who want parametric CAD with no licence cost.
• Watch out for: support comes from the community rather than a vendor, and its many workbenches mean a learning curve.

2. Autodesk Fusion: best for design, CAM and simulation in one cloud-connected tool

Autodesk Fusion, previously called Fusion 360, is a product design tool that combines 3D CAD, CAM and simulation, built around cloud-connected data and collaboration. Teams use it to model parts and assemblies, prepare CNC toolpaths, run simulations and share designs.

Autodesk offers a free personal-use licence for qualifying non-commercial hobbyists, with eligibility rules and feature limits listed on its site, and paid subscriptions for everything else. Compare options on the Fusion alternatives page or the Fusion entry.

• Best for: makers and product teams who want to go from model to machining in one program.
• Watch out for: it is closed source and cloud-connected, and the free licence is limited to non-commercial use that meets Autodesk's eligibility rules.

3. SolidWorks: best for professional mechanical engineering teams

SolidWorks is Dassault Systemes' 3D CAD software for mechanical design, simulation and product data management, positioned for businesses of any size. It provides 2D and 3D product development tools, and the wider portfolio includes browser-based and mobile-ready applications as well as DraftSight for 2D drafting.

It is commercial software, and Enlisted's data shows no free plan. See the SolidWorks listing and SolidWorks alternatives for comparisons.

• Best for: engineering teams that need simulation and data management alongside CAD.
• Watch out for: it is paid and closed source, so budget for licences and confirm platform requirements with Dassault Systemes.

4. Onshape: best browser-based CAD with built-in version control

Onshape is cloud-native CAD that runs in a web browser, so there is nothing to install and several people can work on the same design at once. Its defining feature is built-in version control: designs can be branched, merged and compared much like source code, which reduces the file copies and conflicts that come with desktop CAD.

Onshape's pricing page lists a free plan for personal, non-commercial projects in which all documents are public, plus paid plans per user. The Onshape page shows the catalogue data.

• Best for: distributed teams and students who want collaboration and versioning without managing files.
• Watch out for: free-plan documents are visible to the public and limited to non-commercial use, and it is hosted only.

Best for 2D drafting

If your work is floor plans, schematics or technical drawings, a 2D drafting program is lighter and often cheaper than full 3D CAD. DWG is the file format most drafting tools exchange.

5. LibreCAD: best free 2D CAD for drawings

LibreCAD is a free, cross-platform 2D CAD program that reads DXF and DWG files and writes DXF, DWG, PDF and SVG. It is built with Qt and draws points, lines, circles, ellipses, splines and other primitives, and it can convert a DXF drawing to PDF, PNG or SVG from the command line. It is released as free software under the GNU GPL version 2, and its interface is highly customizable.

The project notes that the macOS build is ad-hoc signed, so the first launch needs a manual approval step. Check the LibreCAD page for current releases.

• Best for: makers and small shops that need free 2D drawings and DXF conversion.
• Watch out for: it is 2D only, so it will not replace a 3D modeller.

6. AutoCAD: best for DWG-based drafting in architecture and engineering

AutoCAD is Autodesk's 2D and 3D CAD software for technical drafting, widely used in architecture, engineering, construction and manufacturing, and its DWG format is a common exchange format for technical drawings. It offers drafting and annotation tools, layers, blocks, dimensioning, plotting and 3D modelling, and can be customized with scripts and add-ons.

Enlisted's data shows it as paid with no free plan, so confirm current plans and platforms on Autodesk's site. See the AutoCAD entry or AutoCAD alternatives.

• Best for: professionals who exchange DWG files with clients, consultants and contractors.
• Watch out for: it is paid and closed source, and Enlisted's data shows no free plan.

7. BricsCAD: best DWG-based alternative with a range of product levels

BricsCAD is a CAD platform built on the native DWG file format, offering 2D drafting, 3D modelling, mechanical design and BIM tools in one environment. It comes in five levels: Lite for essential 2D, Pro for professional 2D and 3D, Mechanical for manufacturing documentation, BIM for building modelling and Ultimate, which combines mechanical, building and surveying tools.

The vendor offers a free trial, and Enlisted lists yearly subscriptions with perpetual options. DraftSight, covered on its own listing, is another DWG-focused drafting product with a free trial. See BricsCAD's page.

• Best for: teams that want a DWG-centred CAD tool and can choose a level that matches their work.
• Watch out for: it is paid and closed source, so match the level to your needs before you subscribe.

Best for 3D modelling and 3D printing

These tools create models for printing, visualization or design. Some are engineering-oriented, others artistic, and none of them replaces a slicer, which prepares the final print.

8. Blender: best free 3D creation suite for organic and artistic models

Blender is a free and open-source 3D creation suite covering modelling, rigging, animation, simulation, rendering, compositing, motion tracking and video editing. It is released under GPL version 3 and written mainly in C++, and studios and individual artists use it to produce models, animations and rendered images.

It is not a parametric CAD program, so it is a better fit for sculpted or artistic shapes than for parts defined by exact dimensions. The Blender page tracks its activity.

• Best for: artists and makers modelling figures, props and printable art.
• Watch out for: for engineering parts defined by dimensions and constraints, a parametric tool such as FreeCAD or Fusion is the better fit.

9. OpenSCAD: best for scripted, precisely parametric parts

OpenSCAD is free software for creating solid 3D CAD objects on Linux and UNIX, Windows and macOS. It is not an interactive modeller: it works like a 3D compiler that reads a script describing the object and renders the model from it. The two main techniques are constructive solid geometry and extrusion of 2D outlines, and it reads and writes DXF, STL and OFF files.

Because designs are text, it is easy to change parameters or produce configurable designs, and the files fit naturally into version control with Git. See the GitHub alternatives guide if you want a place to host them, and the OpenSCAD listing.

• Best for: programmers and makers who prefer describing a part in code to dragging shapes.
• Watch out for: there is no point-and-click modelling, and the project says it focuses on engineering objects rather than artistic work.

10. Tinkercad: best free browser tool for beginners and classrooms

Tinkercad is a free, browser-based app from Autodesk for 3D design, electronics and coding. You build models by combining and subtracting basic shapes and can export designs for printing, which is why beginners, students and teachers often start here.

Autodesk provides it at no cost as a hosted product with no self-hosted option. See the Tinkercad page or compare similar tools in Tinkercad alternatives.

• Best for: first-time designers, students and teachers making simple printable parts.
• Watch out for: it models from basic shapes, so it suits simple parts more than complex engineered assemblies, and it is hosted only.

11. SketchUp: best approachable 3D modelling for architecture and woodworking

SketchUp is a 3D modelling application used by architects, interior designers and woodworkers, known for an approachable drawing approach that lets people create 3D forms quickly without advanced CAD training. Typical uses include concept models of buildings and rooms and furniture or cabinetry designs, often extended with plugins and online model libraries.

Enlisted's data lists paid plans per user, with free access limited to K-12 schools and a free trial offered. Confirm current editions on the SketchUp site, and see the SketchUp page for the catalogue entry.

• Best for: designers and woodworkers who want quick concept models.
• Watch out for: it is paid and closed source, with no general free plan listed.

12. Rhino: best for precise free-form surfaces in industrial design

Rhino, also called Rhinoceros, is a 3D modelling application built around NURBS geometry, a precise mathematical way of describing curves and surfaces. It is used in industrial design, architecture, jewelry design and marine design, is widely extended through plugins, and includes the Grasshopper visual programming environment popular for generative and parametric design.

Enlisted lists it as a perpetual licence with a free evaluation period, and separate commercial and student prices. See the Rhino listing, and confirm current platforms on the vendor's site.

• Best for: designers who need accurate organic surfaces, jewelry or architectural forms.
• Watch out for: it is closed source and commercial, so confirm platforms and current licensing on the vendor's site.

More tools worth a look

A few catalogue entries solve narrower problems. KiCad is an open-source suite for drawing circuit schematics and laying out printed circuit boards on Linux, macOS and Windows. For 3D printing, the open-source slicers PrusaSlicer, OrcaSlicer and UltiMaker Cura turn a finished model into printer instructions. At the larger end, Autodesk Inventor and Siemens NX are commercial mechanical and integrated CAD, CAM and simulation products. If you work with large model files across teams, the best cloud storage guide covers where to keep them.

How to choose CAD software

Start from the job and the cost you can accept.

A practical path for a hobbyist is to start with Tinkercad or FreeCAD, add a slicer when you begin printing, and move to Fusion or Onshape when you want assemblies and manufacturing tools. Open-source picks such as FreeCAD, LibreCAD, OpenSCAD and Blender cost nothing to try, and the 3D and CAD category lists more.
