Vertical Dimensions using ASME Y14.x std
Vertical Dimensions using ASME Y14.x std
(OP)
I had to convert my drawings from ISO to ASME std.
In accordance with ASME Y14.5M standard
the "dimensions should be placed on drawing
to read from the bottom of drawing" ( section 1.7.5.2 ).
That means a vertical dimension is written in horizontal way .
But the standard uses "should" and not "shall" verb.
So , in your experience, for ASME std,
is it accetable that a vertical dimension is written in vertical way, parallel to dimension line ,
to be read from right ?
Thank you
Pier

On "horizontal" dimension you can place numbers above dimension line "ISO-style", but your vertical dimensions still have to have numbers positioned horizontally.

This does leave other orientations as allowable, just not preferable. If it read "shall", this would not be the case.

1. Do it unless there is a really, really, really good reason in your specific case not to.
2. Most on the committee thought 'shall' was appropriate but there was some hold out who didn't think they could mandate it for everyone all the time - or similar.
I generally comply with 'should' statements and very rarely do my own thing - for what it's worth.
In CAD getting the text orientation to change should be simple by changing dimension style or whatever your CAD system calls it. However, correcting the layout of the dimensions on the drawing could be problematic if changing text orientation messes things up. i.e. it may be necessary to space the dimensions further apart, or stagger the text etc. to avoid dimensions interfering with each other.

I hope OP realizes that such conversion is not just a matter of changing a text orientation or switching from comma to point in decimal mark.

I know that the difference in dimension orientation is not the worst problem in conversion to ASME drawings.
Anyway it could be the most "apparent" difference and, also in my opinion, it's not so practical.
I also know that the word "should" give me a chance, but I wonder if a "ASME quality responsible" could reject my drawings with vertical dimensions written with right oriented text or with different type of decimal mark.

This requirement is probably one I'd put under my first definition "1. Do it unless there is a really, really, really good reason in your specific case not to."
I'm thinking you may have reasonable justification for exercising the lee way in should - any way you can check in advance with "ASME quality responsible" pointing out the relevant section of the standard says 'should'?

There is a valid reason for the horizontal text orientation requirement in the ANSI/ASME drawing standard. It prevents mistakes in reading of the dimensions. Drawing paper is cheap, so there is no justification for using vertical orientation of dimension texts just to save space.
RE: Vertical Dimensions using ASME Y14.x std
Sure, changing the dimension scale shouldn't take long, but oops now the dimension text cross over each other and interfere with leader lines and geometry...
OK, so just change the spacing between dims, (we are still on an older version of our CAD which only partially automates this process (mostly when placing dims originally not editing them) so this can be time consuming in itself. Maybe other CAD systems do better.
However, even then it may be that increases the spacing means you need to go to larger sheet size, or second sheet to fit it in but that has time associated with it.
Oh, you have rules about needing to show removed views properly and not faking the projection line arrows etc., sorry can't change a conventional ortho direct projected view to a removed one - you need to recreate that view...
Oh yeah, don't forget you have several dozen drawings to do this to.
Suddenly, living with vertical dimensioning on the updated legacy drawings looks more attractive.
