FreeCAD is a versatile, open-source parametric 3D modeling software created for the purpose of designing tangible objects in various sizes. Its parametric modeling feature enables users to easily revisit the model's history and alter its parameters, facilitating design modifications. With FreeCAD, you can create constrained 2D sketches that serve as foundational elements for constructing additional objects. The software encompasses numerous components that allow for the adjustment of dimensions and the extraction of design specifics from 3D models, aiding in the production of high-quality, ready-to-use drawings. As a cross-platform tool compatible with Windows, Mac, and Linux, FreeCAD offers extensive customization and extensibility options. It supports a wide array of open file formats, including STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE, and many more, which enables smooth integration into various workflows. Designed to accommodate diverse applications such as product design, mechanical engineering, and architectural projects, FreeCAD caters to a broad audience. Regardless of whether you are a hobbyist, an experienced CAD professional, a student, or an educator, the user-friendly interface of FreeCAD ensures that everyone can find their place within the software. Embracing the community-driven development, FreeCAD continues to evolve, incorporating user feedback to enhance its functionality.

Onshape is a fast-growing cloud-based CAD and PDM platform built for modern product design teams that need reliable access, collaboration, and data control. Because it runs on any device, users can work from a web browser, iOS app, or Android app without installing software or maintaining local files. The platform combines CAD, built-in PDM, version control, branching and merging, real-time collaboration, and secure data management in one system. Onshape helps eliminate many limitations of traditional desktop CAD, including crashes, corrupted files, manual upgrades, hardware dependency, and file-based collaboration bottlenecks. Teams can track every design change with a full audit trail and use infinite undo to roll back when needed. Its cloud-native architecture allows distributed teams to work from the same source of truth instead of sending copies back and forth. Onshape also supports ECAD and MCAD collaboration through the Onshape Altium Connector for bi-directional cloud data exchange. It offers plans for professionals, enterprises, students, educators, hobbyists, and startups, making it flexible for many types of users. With automatic updates every few weeks and no downtime, Onshape helps teams stay current while accelerating product design and collaboration.
