custom dimensions

Just wondering if anyone knows if there is a way to create a new dimension style that will automatically deduct 2" from each dimension that I draw.

I am putting lengths of pipe on a drawing and i need to put the cut length of the pipe as well as the center to center dimension. The cut length is usually 2" shorter than the center to center dimension.

I don't want to have to go in and manually change every dimension.

I'm using 2000i

Thanks in advance,

Jason

 

This is kind of an off the wall idea, based on my ignorance, but
what if you use a suffix?

For example: in the suffix option, place: "(SEE NOTE N)", and then
someplace conspicuous place a large "NOTE N" that states that the "Cut
Length is 2" shorter than the center to center dimension shown".

Would that work?

We dimension the cut length, not the center to center.

 

Even if i do only put the cut length on the drawing, i still do not want to manually deduct the 2" from each dimension.
I would like to use a continuing dimension that would automatically deduct the 2" as i go.

 

I guess I'm confused as to your methods. We dimension to the ends of the pipe, that is the cut length. There is no manual editting required.

Since I have no idea as to what type of work you are doing I am in no way
insinuating you are in-correct. However, just to broaden my personal
knowledge, I have to ask.....why? I was a pipe-fitter for twenty years in
the petro chemical and refinery industries and NEVER had drawings
dimensioned to end of pipe. Every thing is done center to center, unless
there is no fitting on the pipe. I have been drafting (piping design) for
the last six years in the same industry, including some off-shore work, and
I (and every one I have been associated with ) dimension all pipe center to
center.

 

I'm not sure what he's doing either, but just to clarify, we dim C/C on plans and ISO's. But we also do CUT Sketches for assembly line fabrication, these sketches are dim'ed end to end using custom arrowheads with end finish/setback/throat notation

Ahhh, hadn't thought about the fab shop aspect. I do remember a shop
foreman telling me once they created "flat" drawings w/ cut lengths. (Cut
sheets?) Than the fitter could have his helper gather the fittings and make
the cuts with out having to read the whole drawing.

Makes sense now, thanks.

 

industry standard dictates pipe work is dim center to center.
this is common to my job, i dim cen to cen on weldment, list actual cut length in bom, not really a hard one guys.

 

that's right.

i guess i should have told you that i'm in the fire sprinkler industry. our fitters and fab shop like to have the cut dimension of the pipe when we use screwed fittings. it makes it easier for the guys in the field and less mistakes in the fab shop.(less thinking on their part)

anyway, i know that acad is not the best prog for sprinkler design and that there are actual sprinkler design programs out there but unfortunately this is all that i have to work with.

i'm not very good with vba or lisp, just picked up a book on them. but if anyone could help me with getting something going that would be appreciated.

thanks
