creating drafting standards
i have been asked to create a drawing standards manual for my company. does anyone have any suggestions on how to begin? or are there any online resources that would help me get started?
find a job or post a job opening
why try to reinvent the wheel?  get copies of the standards listed in
halfrack-
i agree with madmango.  why reinvent the wheel?  capitalize on the knowledge of others and on industry standards.  genium publishing bought the rights to the general electric drafting room manual years ago and has been maintaining it ever since.  this manual places strong emphasis on the basic asme and ansi standards that (in my opinion) are the fundamental underpinnings of any effective drafting function.  i have brought it into several companies that i have worked for in the last ten years.  it is a very thorough and comprehensive source of information on drafting and design.  do a google on "genium publishing" and you'll find it.

here's another list of drawing standards.
halfrack, i applaud you for taking the time to standardize the company. follow the others advise above and stick to it. a lot of comanies these days don't follow drafting standards or don't understand them. good luck

halfrack,
what you'll find is that at the end... you'll be writing cad standards for the engineering group. that's what is really needed, because people go off in tangents with cad.

drafting standards are defined by industry groups. what you need are a set of references to the industry standards that your company wants to follow. if you are setting up a cad system, then set the cad program default settings to give you the drawing standards you are looking for.

"fixed in the next release" should replace "product first" as the ptc slogan.

there are some good suggestions and locations of standards listed above.
just make sure to include pertinent information to the standerds you choose to follow.
i am in packaging and it never seems to fail that packaging engineering schematics have a high rate of redundancy while failing to include things such as the view of the drawing or critical dimensions. the view is important in drawings that are not symetrical in order for the design to function properly or to match up to print. many times we have to go back and get the information which in most cases is no big deal. however, sometimes its like pulling teeth from a tiger.
do not re-invent the wheel but make sure the rim lines up with the lug nuts of your car.  
those referenced standards are confusing and have to be purchased. y14.100-2000 is only a small pamphlet, gives numerous references to other documents that you also have to buy, and is of little real help except to make you aware that sae is grossly overcharging for what is little more than a reference index. my recommendation is to go to the public domain, download a manual like the nasa engineering standards drawing manual, and use it instead.
i just finished writing a drafting standard for our company.  the first step was to identify the problems being caused by over-reliance on tribal knowledge and general understanding of the asme y14 series.  next, i had to familiarize myself thoroughly with certain core standards (y14.100, y14.1, y14.2m, y14.5m, y14.24, y14.34m, y14.35m) to understand their limits and any tailoring needs.  
when i wrote the procedure, i referenced all of the applicable standards, and only discussed specific provisions where necessary to capture (or contradict) local historical practices.  cad issues were left out almost entirely, to be captured in a separate procedure.
the most valuable reference was genium publishing's online version of their
