SOLVESPACE is an open-source parametric 3D CAD software released under the GPLv3 license, allowing users to design 3D components and create drawings through various operations such as extruding, revolving, or using Boolean methods like union, difference, and intersection. It also enables the modeling of 2D parts by allowing users to draw a single section and export it in formats like DXF, PDF, and SVG, while the 3D assembly feature aids in checking component fit. For those interested in 3D printing, parts can be exported in STL or other mesh formats compatible with the majority of 3D printers. Additionally, it supports the preparation of CAM data, enabling the export of 2D vector art tailored for waterjet machines or laser cutters, or generating STEP and STL files for integration with third-party CAM software for machining processes. The tool is particularly useful for mechanism design, utilizing a constraint solver to simulate both planar and spatial linkages, accommodating various joint types such as pin, ball, or slide joints. Instead of relying on traditional trigonometry and spreadsheets, users can work with live-dimensioned drawings to handle plane and solid geometry, and they can sketch sections utilizing a variety of shapes including lines, rectangles, datum lines, points, circles, arcs, and cubic Bezier segments, along with C2 interpolating splines and more intricate designs. This comprehensive approach encourages creativity and efficiency in the design process, making SOLVESPACE a valuable asset for engineers and designers alike.
