The drawing requirements for rev history also depends on it being a level 1, 2, or 3 drawing. When following the DOD-D-1000 and/or DOD-STD-100, you can have a mono-detial drawing, multi-detail drawing, inseperable assembly drawing, or several others. MadMango stated that you should only have one part per drawing, which isn't necessarily true. What industry do you work in? And do you have a contract with your customer as to the drawing requirements? "The attempt and not the deed confounds us." RE: ASME Y14.5 1994 swertel (Mechanical) 6 Aug 02 10:06 The bottom line is to document any changes so there is no room for errors or different interpretations. On the drawing, changed features or dimensions are flaged with the new revision level inside parenthesis.Īccording to the 9th edition of the DMR by Global Engineering Documents, section 23.5 Identifying Revisions on Drawings, you can do the following:Ī) Describe the change in the Revison History block, with zone locators for clarity.ī) Reference the ADCN/DCN of the change in the Revision History Block.Ĭ) Place a revision symbol in the field of the drawingĭ) Any combination of A, B< or C above for ease of tracking. Some companies (like mine) don't put any information in the revision block, and reply on a well detailed Document Change Notices (DCN) to document the changes. Other companies may only truncate the changes, and put the most drastic change in the block. Some companies require every change to be displayed, many times resulting in the first page of a drawing to be nothing but descriptions of revision changes. My personal opinion anyway, I have seen only one page rev'd, and I have seen all pages rev'd, prefering all pages to be rev'd.Īs for the revision block in the corner of the drawing, each company is going to do something different. First off, your drawing should only reflect 1 part, so regardless of how many pages the drawing has, if the part has changed, then each sheet should reflect the new revision level.
