I created a new line type from a shape file. When i drew this linetype and then exported the drawing to pdf, I received the error message in the picture. It said the SHX files are missing, but when I looked in the folder, the SHX files were still there.
When export to pdf completed, I was left with a broken shape shown in the attached pdf.
Is the path to the SHX files in your Support Files Search path?
Which PDF output driver (or PC3) are you using?
Not sure if this will matter, but can you look for options in the PDF driver to include fonts in the PDF?
Can you post a sample DWG and the SHX?
I simply deleted the files, and started again making sure everything was in the same folder and pointing in the right direction.
