An industrial designer shapes the physical products people use every day, from kettles to power tools to medical devices. The job is a loop: understand a real person's problem, sketch many ideas, build quick models, test them, and then work with engineers and factories so the design can actually be made at a sensible cost. Most US employers hire people with a bachelor's degree, but what gets you hired is a portfolio that shows your process, not just pretty renders. You can build that portfolio for free: learn sketching by drilling, learn CAD with free tools, make cheap cardboard and foam model

Stage 1 of 4 · about 14 weeks
Learn to draw ideas fast and clearly (perspective, line quality, shading, ellipses), understand the design process (research, ideate, prototype, test), and make your first 3D models in free CAD. Practice: sketch 10 everyday objects a day in 2-point perspective, then take apart a cheap appliance and note how it is held together. Finish by modeling one simple object, like a mug or a stapler, in Fusion for personal use or Onshape free.
Fast, clear sketching and perspective
Sketching is how you think and talk as a designer. In meetings with engineers, marketers and customers, a quick clear drawing gets a idea understood and fixed in minutes. O*NET lists preparing sketches and drawings as the first core task of the job.
The design process and product teardown
Products succeed because of a process, not a flash of talent. You will research who uses a thing, generate many ideas, build rough prototypes and test them. Taking things apart teaches you how real products are manufactured, which O*NET calls out as evaluating feasibility and researching production methods.
First 3D modeling in free CAD
Sketches show an idea, but CAD makes it real and measurable. Engineers, model makers and factories all need accurate 3D files. SolidWorks and similar parametric CAD tools are core software in this field, and you can learn the same concepts in free tools.
Then 3 more stages (about 120 weeks in all) with lessons, drills, projects, 10 interview questions with strong answers and free resources.
