Poor Drafting Practices
You have hit my HOT button. As an official old-fart, I began engineering work before CAD was even available. IMHO, no one ESPECIALLY STUDENTS, should be allowed anywhere near a CAD system until they are familiar with the smell of eraser dust from a for-real drafting board! Only after they learn how to create a good drawing should they then be allowed to try it on CAD. CAD does not a good drafter make!
