This is a screen capture of Autodesk's free 123D Design (showing the Windows version, but it also runs on Mac and as a powerful online Web app). That one is also free, but is (fully optional) tied to suppliers (they give free model dimensions, so you can incorporate them in your design). Another program where I am playing around with at this moment is DesignSpark Mechanic. You also can use the (free) open source programs like LibreCAD or OpenCAD. Interests AI / ML (artificial intelligence / machine learning in AEC or Manufacturing) AEC Industry CAD or BIM Architecture Visualization CAE / FEA and Simulation Technologies Computational or Algorithmic-aided design (AAD) CDEs or Cloud-based Project Management Technology Drones and 3D Laser Scanning and Measurement Systems MCAD and PLM Process and Plant CAD/BIM Robotics in AEC or Manufacturing VR / AR / MR Immersive Technologies As an Xpresso reader, you will hear from some of the most important voices inventing and using the very latest tech in areas such as AI, machine learning, algorithm-aided design (AAD), AR, VR, MR, 3D printing, 3D computer vision, robotics, and SmartCities technologies. INSIDER Xpresso keeps CAD industry professionals up-to-date on next-gen emerging technologies (emTech) that will revolutionize the worlds of AEC and manufacturing and design. Within a few clicks you will begin to see how the elements interact and how to refine your design to give you ideas shape. You initiate the design or creative process by selecting one of the basic shapes provided. No matter if your 3D design a Raspberry Pi case or any other object, a sketch in hand is always a good idea. This sketch helps to keep in mind the overall picture and is a good reference point when getting stuck in the modeling process. Before getting started on his computer, Ben draws a rough sketch of what he will be creating later.
