Machine Shop: Lesson 3 - Drawing, Dimensioning and Tolerances
Drawing are the most effective and efficient way the engineer has to communicate designs ideas to those who are assigned the task of implementing them. This class reviews drawing and the difference between Isometric and orthographic views. Other topics discussed are the various dimensioning methods and the preferred method for submitting drawing to the MEEG shop.  |
Isometric and Orthographic projection
Below is an example of a drawing using Baseline Dimensioning discussed in class.

One area that is often over looked in student drawings is the tolerance value of parts and a list of materials. Time is money, the larger the permissible tolerance and yet still meets the need of the designer, the faster and less costly is the fabrication process
