Dune 3D operates as a parametric 3D Computer-Aided Design (CAD) software. It provides users with the capability to sketch and constrain both in 2D and 3D dimensions. Furthermore, it allows for the addition of chamfers and fillets to designs.
Integrated CAD, CAM, and CAE suite offering cloud modeling, simulation, and manufacturing tools with collaborative editing, free-form and parametric design, licensing for students, hobbyists, and startups, plus support for 3D printing and CNC machining.
Fusion has a mode similar to Tinkercad, but is expanded into a pipeline of modifications with additional features.
Onshape is a professional CAD system – Parts, Assemblies, Drawings – with version control and collaboration built in. Each Onshape plan (Free, Education, Professional, and Enterprise) gives you all of the CAD and data management functionality with no time limit.
BRL-CAD is a powerful cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for...
MatterControl is a free, open source app that lets you organize and manage your 3D prints. It's designed to help you get the most out of your 3D printer - making it easy to track, preview, and print your 3D parts.
SolveSpace is a parametric 3D CAD program with extrude, revolve, union and difference functions. Save/Export as DXF, PDF, SVG, STL, STEP. Mesh generation expected by most 3d printers. Constraint solver point tracing for motion analysis.
Vectary is the most accessible 3D and Augmented Reality design platform. Create an account for free online. No app download needed. Build immersive experiences for the real world. Publish 3D and Augmented Reality content to any website.
Womp is a free and beginner friendly browser based 3D design software, allowing anyone to easily create professional and 3D printing ready creations live from virtually any device and without any technical knowledge.
KTechLab is an IDE for microcontrollers and electronics. It supports circuit simulation, program development for microcontrollers and simulating the programmed microcontroller together with its application circuit.
SimulIDE is a simple real time electronic circuit simulator. It's intended for general purpose electronics and microcontroller simulation, supporting PIC and AVR. PIC simulation is provided by gpsim and avr simulation by simavr.
