Title: Repair Mtext & Dimension Fractions
Post by: CAB on August 14, 2013, 09:49:21 AM

I sometimes get converted files from Micro Station and the fractions do not convert.
Last file had over a hundred of these and very time consuming converting them by hand.
The worst part is missing one or two buried in large mtext objects.

They show up in the Mtext & dimensions as ? or in the data as :
Mtext  (1 . "{\\fFDOT|b0|i0|c0|p2;\\U+0182\" Ø Round Bar}")   --->  (1 . "\\A1;{\\fFDOT|b0|i0|c0|p2;\\H0.7x;\\S3#4;\\H1.429x;\" Ø Round Bar}")
Dimension (1 . "{\\C256;2\\U+0185\"±}")
Any suggestion's as to how you would attack this problem?

Example DWG attached.

OK, found this on the net. Looks like a special font was being used to create these 018n codes.
Now I can do a search & replace with lisp.

eSize[0][0]=0xFEFF; /* 1/16 */
   eSize[0][1]=0x0187;
 
   eSize[1][0]=0xFEFF; /* 1/8  */
   eSize[1][1]=0x0183;
 
   eSize[2][0]=0xFEFF; /* 3/16 */
   eSize[2][1]=0x0188;
 
   eSize[3][0]=0xFEFF; /* 1/4  */
   eSize[3][1]=0x0181;
 
   eSize[4][0]=0xFEFF; /* 5/16 */
   eSize[4][1]=0x0189;
 
   eSize[5][0]=0xFEFF; /* 3/8  */
   eSize[5][1]=0x0184;
 
   eSize[6][0]=0xFEFF; /* 7/16   */
   eSize[6][1]=0x018A;
 
   eSize[7][0]=0xFEFF; /* 1/2  */
   eSize[7][1]=0x0180;
 
   eSize[8][0]=0xFEFF; /* 9/16  */
   eSize[8][1]=0x018B;

If you use a font which has those characters defined you might not need to convert them. E.g. Arial Unicode MS has them, including lots of others. See attached.

That would simplify things but I don't see 16th in there.
I'll take a look later today, work calls. :)
Thanks for the tip.

You're correct! Didn't realize. It seems the Oriya fractions aren't implemented in the Unicode Arial, only the Vulgar fractions.

I wonder what font MS is using, or if it's some internal font of their own.
