Course Overview
CAD 1
Computer Aided Drafting also known as CAD helps to develop basic mechanical drawing skills, these can be used in 2-D as well as 3-D drawings and they can be used to create drawings by hand or by using a computer software. In this class students get an understanding of mechanical drawing and layout work often necessary in today's professional CAD industry. In the class we do, hand drawn mechanical drawings, AutoCad drawings, OnShape drawings, 3D printing, and architecture.
Mechanical
The first method of drawing we used in the course was mechanical drawing. This form of drawing requires precise measurement and line placement. Drafting tools were used to assist in drawing the neatest work possible. The idea of darker, sharper, and crisper lines was repeated throughout the course to make sure our lines and drawings were neat and professional.

AutoCad
The second method of drafting used in this course was a program called AutoCad. AutoCAD, developed and sold by Autodesk, was first made available as a desktop application for microcomputers with internal graphics controllers in December 1982. AutoCAD is utilized by professionals such as architects, project managers, engineers, graphic designers, and city planners in industry. In 1994, 750 training centers around the world supported it.

OnShape
Our third method of drafting in this class is a software called OnShape. Onshape is a professional CAD program designed for engineers who want to design parts and model mechanical systems. It is a highly advanced web application that can be used to design anything, anywhere, and with anyone. OnShape can be used to create 3-D objects and look at them from different views. Material can be added and weight can be viewed, as well as moving parts to create almost any product for manufacturing.

3D Printing
This is a small keychain that I designed and printed for 3D printing. I used a software called Fusion360 to design it and used FlashPrint to convert to an .x3g file in order to print using a Flashforge Creator Pro 3D printer. For the actual 3D print I decided to do a football with a mustang and SW MUSTANG FOOTBALL written on it. I chose this because I thought it would be a keychain that would sell well because football is a very popular sport at our school.

Architect Presentation
The first part of our architecture unit was a slideshow presentation on a famous architect of our choice, I chose to do Argentinian architect César Pelli.
Architecture
The second part of the architecture unit was a demonstrated 2-car garage using the software pragram Revit. Revit is made by Autodesk, the same creators of AutoCad, a previous software used in the course. Revit is an architecture soft ware that, model shapes, structures, and systems in 3D with parametric accuracy, precision, and ease.

Conclusion
In conclusion CAD 1 is a great class to learn the basics of CAD and the history behind it. Mechanical drawings help understand the drafting industry before CAD existed and it gives you a foundation to start with. The different software packages utilized are only some out of many out in the industry, but are some of the more popular options.
