Standards help

[AMontembeault]

I remember, waaay back in the day when I was first learning how to draw, my instructor defined how borders needed to be drawn - specifically how far from the edge of the sheet (something like 8mm if I recall correctly). I also seem to recall that inside the border, views, dimensions, annotations, etc. should also be no less than a set distance from the border, for clarity - but for the life of me, I can't find in any standard where this value is called out (nor can I remember what the value he told us was - I generally just err on the side of caution and try to be as generous as possible). Certainly I can find the dimensions between border and sheet edge in relevant standards, but nothing inside the borders - anyone know where I might be able to find this info? Logically one might assume that if dim lines are to be ideally 10mm from an edge or surface in a drawing view (per asme y14.5-2009 1.7.1.2, with dims ideally being 6mm from eachother, then 10mm spacing from a border or title block edge, for example, would also be appropriate - I'm just looking for something more definitive. We have designers who are challenging our checkers when being marked up for having dims/section lines or other annotations too close to the borders, and we'd like to put a nail in this coffin either way.

Thanks

While I've run into checkers making up their own rules and drafters making less than pretty drawings I've never seen any rules about dimension placement location dimensions.

If it's desired to control it you'll need to get company standards and HR involved.

This sounds more like a money wasting fight for control than a drafting issue.

I thinks some places did have rules for this, not clear if they were ever in ASME or even the older ANSI or MIL stds.

Former boss with background in defense/automotive once pointed this out on a drawing of mine - but I don't have a reference.

I just try to keep far enough in from the borders so it doesn't look messy, no specific #.

Other than the distance from the part and between dimensions, I don't think there are hard and fast rules. A rule of thumb I was taught when starting out on the board is to leave enough room to allow for addition of future dimensions should the part be significantly revised, but that doesn't present the same problem with CAD as it did with board drawings.
Bottom line is making the drawing easily interpreted.
