How do I create something or start a project like how do I get to designing something from scratch.
Depends on the type of project you wanna make. Firstly make a rough drawing and then refine it. Always keep in mind that what kind of production technique you are going to use to produce the component. If the production technique is 3D printing then there are no limitations except the size and strength of the product. other then the 3D printing, you have to consider the limitations , possibilities and off-course the cost of production. Making a CAD model of your project greatly helps you to understand the complications you may face while manufacturing your project. I hope this helps!
