Reviews and comparisons of computer-aided design (CAD) and 3D modeling software, from free tools to industry-standard platforms.
OpenSCAD is free, open-source CAD software for creating precise 2D and 3D solid models from code. Instead of drawing features interactively, you write a script that defines the geometry, parameters, and operations, then the application generates the model. That makes it especially useful for parameter-driven parts, 3D printing, procedural designs, and repeatable models. For engineers … Read more
Revit is Autodesk’s Building Information Modeling (BIM) software for architecture, structural engineering, MEP engineering, construction, and multidisciplinary building projects. It connects 3D building models with drawings, schedules, quantities, and project information so changes can flow through related documentation. The current major release is Revit 2027, and Revit 2027.3 is the latest update as of September … Read more
FreeCAD is a free, open-source 3D CAD program used for engineering and product design. It lets you build precise 3D models, sketches, assemblies, and technical drawings. It also comes with tools for FEM (strength and stress testing), CAM (machine tool programs), BIM (building design), and Python-based scripting. FreeCAD runs on Windows, macOS, and Linux, which … Read more
Autodesk Fusion is a cloud-connected product development platform that combines 3D CAD, CAM, CAE, PCB design, data management, and collaboration. The regular U.S. price is $680 per user per year for Autodesk Fusion, while Fusion for Manufacturing costs $2,040/year and Fusion for Design costs $2,190/year. Qualifying users can also access Personal Use, Education, startup, or … Read more
GrabCAD is an online engineering community and CAD library where engineers, designers, and students can find, view, download, upload, and share CAD models. It is not a conventional CAD modeling program such as SOLIDWORKS, PTC Creo, or Autodesk Inventor. The brand also covers software for additive manufacturing, including GrabCAD Print and GrabCAD Streamline Pro. The … Read more
Onshape is a cloud-native 3D CAD and product data management platform for designing parts, assemblies, and drawings in a web browser. It combines CAD with built-in data management, version history, collaboration, and branching, so teams can work with shared design data without a traditional desktop CAD and PDM-server workflow. Onshape is developed by PTC and … Read more
Autodesk Inventor is professional 3D mechanical CAD software for designing parts, assemblies, and products, with tools for simulation, documentation, sheet metal, frames, tube and pipe, cable and harness design, and manufacturing information. It is aimed at engineers and designers who need a dedicated mechanical product-development workflow rather than mainly 2D drafting. Inventor is part of … Read more
Creo software is a professional 3D CAD platform developed by PTC for designing, simulating, and manufacturing complex products. It is mainly used by mechanical engineers and product development teams to create parametric models, assemblies, engineering drawings, and manufacturing-ready designs. Creo is especially useful for industries that require advanced product development workflows, including automotive, aerospace, industrial … Read more
Job postings tell you what employers actually require, not what a vendor wants to sell you. This CAD software job postings analysis pulled real, currently-open engineering job postings from major job boards — Glassdoor, ZipRecruiter, Jooble, and others. It covers mechanical and civil/structural roles specifically, to see which tools actually show up, how often they’re … Read more
Comparing FreeCAD vs SolidWorks means comparing opposite ends of the same market, both covered in more depth in the CAD software guide. FreeCAD is free, open-source, and community-developed under an LGPL2+ license. SolidWorks is proprietary, subscription-priced, and built by a single company with decades of dedicated engineering behind it. Both do real parametric 3D CAD … Read more
