I'm going through the CSWA practice package, and I'm finding a lot of errors. The first thing I noticed was that many of the problems are missing dimensions. I am aware the problems are stated to not necessarily be up to drafting standard, but the dimensions missing are ones that are needed to find the correct mass. I also noticed that I was getting a lot of questions wrong that should have been very simple, with very little room for error, so I started comparing my results with the models in the instructor materials, and I've been seeing a lot of discrepancies. Many of the instructor solutions use different global variables or entirely different dimensions than what is shown in the problem to achieve the result given in the answer key. Is this an outdated file, or a problem that needs to be addressed?
