In the committee meeting yesterday, I shared some really useful links about learning how to create 3D files.
Here is a video that shows you the concepts –
Tinkercad
I recommend starting an account in Tinkercad and doing LEARN lessons
Instructables
I also recommend using Instructables as they have projects with step-by-step instructions. They also have classes that you can join.
When you join Tinkercad you can use your same login for Instructables and Fusion 360.
Fusion 360
Have a look at this simple project to get you started
Sculpting Critters in Fusion 360
Here are the instructions to sculpt a ghost.
Thre are lots of girls in the DT Committee who have done 3D printing. Please share any useful links or ideas for 3D printing in the comments.
