Yes an OCR would eventually recognize only true type fonts and always leads to be controlled in each written word.

Never mind complicated -- I wonder whether it would even be possible, but I doubt it. How AutoLisp could determine which Polylines belong together to represent a letter is beyond my comprehension. They're not affiliated with each other in any meaningful way, for example, the red ones along the top here:

are sequential in the drawing order, so looking at sequential series of Polylines is never going to identify letter groupings. Proximity could not be used, because from many starting Polylines to measure from, there are others that are part of different letters closer than some of those that are part of the same letter. And here are a few of the configurations of (arbitrarily) M and E:

Does it take 57 Polylines to represent an M, or 52? 11 to represent an E, or 14, or 15? The second and third E's look like they might be duplicates, but their longer horizontal parts are of different lengths. The third one has the bottom leg longer than the top arm, though those are the same lengths in the others.

Even if it were possible to determine that the upper left clump of Polylines there belong together to represent a letter, I cannot imagine by what functions AutoLisp could possibly decide that it's an "M". But I'd be interested in anyone's thoughts on how that might be determinable.

It would be quite complicated in LISP. But you can try to export the lines to PDF and then bring back the PDF to AutoCAD with the option "Convert text" enabled. It should recognize real texts. Or the OCR function in AutoCAD Raster Design can do that.]]> Thu, 07 Nov 2024 07:11:49 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=14634&PID=39866&title=converting-lines-to-text#39866 <![CDATA[converting lines to text : Hi there,Find your drawing in...]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=14634&PID=39865&title=converting-lines-to-text#39865 Author: rahul7civil

Hi there,

Find your drawing in that discussion forum is a research project.

You can get the poly line into the text is a bit more complicated using automatic language. If you are doing in the manual is better than automatic functions.

Thanks
