Solidworks CSWA review
Overview
The CSWA test is based on three drafting questions, three parts, and two assemblies. Each drafting question is worth 5 points, each part question is worth 15 points, and each assembly question is worth 30 points. Each part has 2-3 questions based on it, and each assembly has 2 questions. You take the exam in either two 90 minute segments, or one 3 hour segment. The core topics covered are:
- Extrusions, Revolves, and Drafted Pockets
- Dimensions, Relations, and Mates
- Sketching
- Basic assemblies
Practice Problem
Piston: Create the following part using the dimensions given. Material is AISI 1020 steel
What is the Mass of the part (Grams)
- 1200
- 1957.64
- 2271.32
- 1.25
(B)
Advice
The CSWA is a challenging test with extremely draconian accuracy requirements. If you don’t get the EXACT answer on the multiple choice segment of each part or assembly, I would highly recommend fixing the part before moving on to the free response. If you do not, you will likely fail simply because your part is not within the 1% threshold they set for accuracy. Additionally, they do not provide you with instructions, merely dimensions, and deciphering them can be quite challenging. Be on the lookout for parts that require a revolve or added relations, such as tangency. Also keep an eye on the clock, because the three hours can go quickly. I would advise skipping the harder parts until you have completed the easier ones.
