Y14.5M.ttf

This font is public domain freeware - copying & redistributing it is encouraged. 
You may use it in what ever personal or commercial way you would like. Credit to me if it is used in a commercial package would be nice but is not mandatory.

This font follows the guideline of the ASME Y14.5M technical specification. Rather than reverse engineering this font you would likely be better off just going right to the standard for the complete font details.

The font is specifically designed for use in geometric dimensioning & tolerancing. If you are unaware of what GD&T is the following will be pretty much gibberish:  

The font is capable of producing both boxed (basic) & unboxed feature control frames

Use "[" to start boxed dimensions and end with "]". Use the ! character to underline preceeding numbers. 
eg for the 12 basic:

use "[1!2!]"

Use "{"to start feature control frames and end with "]". Use the _ character to underline preceeding letters.
eg to print a feature control frame for:   

use "{k_|0!.!2!|A_|B_m_|C_]"
