For this assignment you will be drawing some objects in 3D. The first object is a toy brick and the second is the servo motor from the previous assignments.

You may use AutoDesk's Inventor Software, Fusion 360, or TinkerCAD to accomplish this. Each has different requirements, bu6t the most important thing to look at is your computer's GPU RAM (Graphic Processing Unit Random Access Memory), and system RAM.

Inventor - Professional level desktop CAD software. This program will probably require a computer with some degree of power

Inventor System Requirements

Fusion 360 - Fusion is functionally the same program as Inventor, but it uses a cloud based backbone. It requires less power in terms of the computing power and will tie your designs to your AutoDesk account.

Fusion System Requirements

TinkerCAD - TinkerCAD is a stripped down version of 3D CAD. It runs in a browser and therefore requires very little computing power to use. You can do all of the 3D assignments in it with a few modifications.

TinkerCAD System Requirements

First some vocabulary for 3D CAD

• Line - A Line is something in Inventor that has length and direction but does not exist in a second mathematical dimension. It is a vector plain and simple.

• Plane - A Plane is something in Inventor that has length and depth, it is a two dimensional object. It has unlimited length and depth and extends infinitely in two directions. A plane can exist at any angle in the x,y,or z direction

• Face - When multiple lines(or curves) connect with each other to enclose a space, they become a face. Faces(or profiles) exist in two dimensions but not three.

• Solid - When a face is extruded or revolved it gains substance in the third dimension and becomes a solid. Solids are the 3D objects that we are trying to build in Inventor.
