What is CAD?
CAD stands for Computer Aided Design and refers to the use of computer systems to aid in the design process.
How CAD Software Works:
While each software application works slightly differently, generally the software creates 3-D models of your design by starting with a 2-D sketch. From there it can be extruded into 3-D and modified using features such as cuts and further extrusions. These models can then be exported as various file types to be used in manufacturing processes such as laser cutting, 3-D printing or CNC machining.
Different Software Available:
- Solidworks
- Most widely used(Industry Standard)
- Very expensive ($4,000)
- Steep learning curve
- Very advanced features
- Rhinoceros 3-D
- Popular in art communities
- Steep learning curve
- Cheaper than Solidworks($995)
- Very advanced features
- AutoCAD
- Free for students
- More advanced than other free alternatives
- Second most widely used software
- Blender
- Free
- Good complex surface modeling
- Not really meant for machining but good for 3-D printing
- SketchUp
- Free
- Easy to learn

Where To Find:
- Blender and SketchUp are free and can be downloaded onto any PC
- Autodesk provides its programs for free to students so AutoCAD can also be downloaded onto your PC.
-
Solidworks and Rhinoceros 3-D can both be accessed through Virtual Andrew.
