drawing standards?

[metiman]

i am working for a company that does follow asme y14.5m-1994 standards...but as far as drawings go all of the designers create their drawings a little different. i would like to create a set of standards which will help all of the drawings look the same. does anyone out there have a set of drawing standards that they are willing to share.

Give them each a copy of ASME Y14.5M-1994 and enforce it.
That will be your standard. The only other standard you may have is how to create/store your CAD files and any company notes you may use.

Try ASME Y14.3

You're doing the right thing to create an internal standard. Y14.5 can be used correctly by different designers for the same design in different ways. Just like in Solidworks, where you can build part models using different approaches and end up with the same shape. I think that it would be difficult, however, to apply another company's standards to your situation, since ideally Y14.5 should be applied to specify design intent, and your purposes for parts that look very much like another company's parts may be different. I'd suggest you start with simple design situations that you encounter often, and have your designers collaborate on finding a best approach to tolerancing those parts, and continue from there. Sorry but I don't think this is a situation for a cut and paste solution.

ASME Y14.100-2004 is your top level standard. I recommend keeping a copy of it on hand. ASME Y14.5M is a child to that standard. ASME Y14.100 makes allowances for each company to create their own standards. Paragraph 1.2 simply says, "Appliacation of this Standard my necessitate tailoring to exclude unnecessary requirements." It also provides a tailoring guide, though I didn't find the guide itself particularly useful.

Basically, create a drafting SOP that simply says something like this at some point: "All engineering drawings and solid models created by [your company] for the purpose of describing its products, parts or other items shall be prepared and changed in accordance with current and applicable American National Standards."

And then says this: "Exclude from practice any portions of any standards (e.g., ASME Y14.5M-1994) that differ from instructions within this SOP."

Then detail the areas where the ASME standards do not apply to your company within the drafting SOP. Hopefully the list of exclusions is short.

This way to you don't have to reinvent the wheel.
