Tinkercad is a nice CAD software for beginners. It’s a free software that doesn’t require a download because it runs in the browser. We also offer course which clearly explains the in’s and out’s of Tinkercad.
For these examples we will be using Tinkercad, but feel free to use whatever software you feel comfortable with.
Search up Tinkercad in your browser and make an account. Once you’ve signed into Tinkercad select new design. This will open up a new workplane.
With any software the first thing you should do is select the bed size. The bed size you input should be the same size as the bed of the 3D printer that you are going to use.
Next, you can edit the project name by pressing on the generated name on the top left of the screen. Left click with the mouse to select shapes and right click to navigate around the plane. The Scroll wheel is used to control the zoom. On the right hand side of the page there is menu featuring Tinkercad’s pre made shapes, to import you’re own 3D shape or model select import at the top right.
