What are the major problems in hand drafting?

Question

I'm doing a research paper on what are the major errors that happen when hand drafting a structure. I would like to hear from drafters that have experience. If you would let me do an online interview it would be much appreciated. Thank you. --EMP

My current thesis statement for my senior project paper is:
Drafting by hand may cost you more time, but presents less error for you than CAD drafting.

Can any of you tell me if it is true or tell me different?

Answer 1

one of the biggest problems is that if you screw up you have to start all over. but with CAD (computer aided drafting) you have the ability to erase and undo mistakes you have made. and since humans are not as precise as computers measurments can be off, which is not a good thing in engineering or architecture. But CAD allows you to type in measurements and give your drawing a desired accuracy. another drawback is that if you are using a bored, pencil, and drafting rulers, you are limited to 2D drawings where as CAD you have to option to draw using a 3 dimensional plane allowing you to essentially build your object from scratch in a computer and even add material layers to it as well as lighting.

Answer 2

Well, I'll give you another error of drafting that come into play either with manual or computer drafting. Sometimes details wind up on a drawing that are pulled from standard detail templates. Occasionally these make their way into drawings without being actually designed for the specific job.

The results are sometimes catastrophic.

Answer 3

Thickness of lines. Acurracy (AutoCAD goes out to many decimal places.) Consistancy, and time.

Answer 4

Will you vote me best answer if you do not get another?

Thanks
