Engineering Graphics 232

In Engineering Graphics 232 we learned all about generating engineering drawings. In particular, we learned about two-dimensional and three-dimensional design, creating and editing solid models, automatically generating orthographic views, section views and the three-dimensional views from solid models, plotting and documentation.

EG 232 ASG 1
EG 232 Assignment 1, with Feedback in red

In the first assignment, we were expected to execute a series of sectional mechanical drawings that were part of a larger assembly. The drawings were all done by hand, but still needed to be neat and precise. The feedback I received was very helpful, and pointed out that I hadn't completely annotated my drawings. Important dimensions and thickness weren't shown. Perhaps more importantly, the cross hairs showing hole centers weren't shown. These are really important to make sure the holes are drilled in the correct places. Getting these just a little out of tolerance can mean all the difference between a part being fit for its intended purpose versus not working!

EG 232 Asg 2
EG 232 - Assignment 2 done with Autocad

The second assignment built on the first, only this time we used the Autocad software package to execute the drawings. I took the feedback from the first assignment on-board. My drawings were fully annotated and the hole centers were clearly shown. The Autocad software made this a little easier to do, although I'm now confident that I could do it by hand too, if I had to.  It's important to know how to do it manually, but it's sure nice to have software to assist with keeping the dimensions and locations accurate. The software also has a library of symbols and parts- all international standards which is important if engineering drawings are going to be recognizable and used globally.
