The program uses two main techniques to build 3D objects: 2D line extrusion and constructive solid geometry (CSG). The software works as a 3D file compiler that can generate 3D models through configurable parameters, allowing the user to change or modify sketches at any step of the design process. It’s oriented to mechanical and industrial design, with limited rendering features. OpenSCAD is a free, open-source CAD software for 3D modeling available for a variety of operating systems including Windows, macOS, and Linux. The software contains intuitive design tools, and the Autodesk online platform offers dozens of tutorials and tips for beginners. TinkerCAD is available for free, focusing on educational purposes, but can also be used by CAD professionals. It also provides circuit design tools and the ability to create buildable brick objects to simulate Lego assembling. The software features all necessary tools to build simple and complex models using layers and blocks. The 3D models created with TinkerCAD are compatible with modern 3D printers and can be saved in STL, SVG, and OBJ formats. TinkerCAD is a web-based 3D modeling program developed by Autodesk in 2011 to create a user-friendly platform for kids and young students to construct simple prototypes and objects using solid geometry. It includes simulation and analysis tools such as Finite Element Analysis (FEA), stress analysis of elements, and CAM/CNC workbenches. It can manage and integrate different file formats such as STEP, IGES, STL, DXF, SVG, OBJ, and DAE.įreeCAD is a valuable tool for professionals and students in engineering and architecture. This software is highly accessible and compatible with all operating systems, including Windows, macOS, and Linux. It also offers 2D sketching with the ability to constrain shapes and geometries and extract details from 3D models for professional drawings. 10 Find the Best CAD Software for Your Needsįree Open-source Software for Beginners FreeCADįreeCAD is an open-source 3D parametric modeling software that allows users to recreate objects and modify their features and properties in the design process.9 Best CAD Software for Electrical Engineering.8 Best CAD Software for Civil Engineering.6 Best CAD Software for Mechanical Engineering.
