http://www.lee-mac.com/boxtext.html

I made this using this code of lee mac. I've modified it a bit and most of it is his code.

 

It was created to make it easy to create searchable pdf files.

(In the shx state has some problem as we all know 

width limited to 1, or printing with PDFSHX as comments, or printing with microstation, or using adobe ocr. etc...)


 

If the space occupied by the shx font and the space occupied by the ttf font match,

there is no problem in most drawings, so I thought like this 

 

Create a bounding box in shx font, convert every STYLE to Arial ttf font,

create a bounding box again, move the starting point (lower-left),

and then adjust the height, and then adjust the width(scale factor).

add move base point option (this option for characters that use below the baseline, like p, g, q, but I think it's unnecessary in general)

add width & height round up options

 

ex) autoarial - N - N - N

make Text like 1921.123 Height & 0.8782 Width 

 

All text can have different values

 

ex ) autoarial - N - Y - 100 - Y - 0.1 

makes Text like 1900 Height & 0.9 Width

 

Texts can have an organized values

 

If you set the round up factor well, you can get a clean drawing.

Rather than drawing a bounding box you can get all the information you need from the textbox (AutoLISP) function.

For merging all Text Styles to Arial Merge text styles (or change text styles) lisp version 4.2 by T.Willey is the bomb!
