Underlined Text
Underlined Text
(OP)
One of our designers is complaining of the distance between text and an underline on our drawings. I looked in ASME Y14.2 and could not find any requirements, other then the obvious "basic requirement for lettering on a drawing is to produce fully legible copies". He claims the space is not enough to produce legible copies. We routinly issue 1/2 sclae (E to C) plotted drawings and in some cases 1/4 scale (E to A).
Does anyone know of a standard that defines the spacing between the text and its underline?
Reference CAD is Wildfire 4m150.

RE: Underlined Text
In my opinion, it is not possible to plot readable copies of E_sized drawings onto an A_sized sheet. B_sized plots are fairly readable. If the end user wants A_sized prints, do not draw anything larger than C_size.
I have seen E_sized drawings done with weird sized fonts in an attempt to make small plots readable. It can sort of work, but the result is an amateurish drawing.
The following font sizes are adapted by me from the 21st edition of the Machinery's Handbook. I could find this in my 26th edition, but it is still useful.
A_size prints can be punched in stored in a binder. B_sized print can be foled and punched, and stored in a binder.

It's best to use the underline fonts in the CAD program to take care of it. I would think underlining of text is rarely, if ever, desirable anyway.
drawoh,
We use these text sizes:
A size 1/8"
B size 5/16"
C size 7/32
D size 5/16
E size 3/8
We find these sizes allow for readable reduced drawings, even E to A, and not at all amateurish.

I assume you are using 3/8" font on your E_sized drawings so that you can print them A_size.
What is the point? I do E_sized drawings so that I can document things that are too complicated to fit on smaller sheets. I do not have room for 3/8" lettering. The E_sized drawing hanging on a wall 10ft from me has 1/4" lettering I can read fairly easily. Perhaps it is 6mm. I can't remember, and I cannot bother moving over to measure it.
I make E_sized drawings so that I can print them E_sized if I want. If I have a requirement to be able to print A_size, I do not exceed C_size.
RE: Underlined Text
Off the top of my head I can't think underlining in the drawing standards except for 'not to scale' dimensions.
As to text size, we settled on .15 after reviewing the standards. This works well enough on an E scaled down to B, and doesn't take up too much extra space except on maybe a B size drawing. However, by the time you have a title block and rev block to the standards and some 'standard notes' there's not much real estate left on a B anyway. We do allow it to be reduced to .12 on B prints if so desired.

RE: Underlined Text
Unfortunately, there are still some large companies that have entire departments dictating just what a "clear and concise" drawing consists of. My current assignment is at such a company. In addition to all view labels requiring underlining, many hours of meetings have occurred attempting to (re)establish policy to require ALL drawing views on all drawings to be labeled, including the obvious standard projections (among other such vital practices, such as whether the scale in the title block should be blank [company preferred], or if "NONE" is allowable [even though the standards are clear on this issue]). If you overlook such requirements, your drawing is sent back and your quality "metrics" take a huge hit. It wouldn't be so bad if the applicable standards were more widely understood and applied, but bickering over different interpretations of such undocumented inconsequential issues have wasted many man-hours.
Meanwhile, tha actual model files are not checked ay anyone.
I sure wish I had that kind of $$ to spend on such important "problems".

2 years later corporate adapts a different CAD/PDM system as the corporate standard and only the original division going to PDM is allowed to keep their system. The division I worked for had to chnage to the new standard CAD/PDM and the other 2 divisions got sold off.
Since then, the division I worked for was sold off and they changed CAD/PDM systems to their new corporate parent standard. At least the engineers who had been through it all knew UG/NX, Pro/Engineer Wildfire and CATIA V5/6. Great resumes!
