What is the difference between the fonts Simplex.shx and Simplex8.shx included with the out of the box AutoCAD installation? With the release of AutoCAD 2005, the Simplex.shx font was updated to include additional character sets. The Simplex8.shx is a renamed version of the original Simplex.shx which was included with versions of AutoCAD 2004 and earlier. Some of the most common character sets ...

After the drawing opens, the command line shows one or more substituted fonts, for example, substituting simplex.shx for archquik.shx. Also, the font, if used in a text style, is indicated as missing when looking at the Text Style dialog box. Sometimes, the text in the drawing may disappear or display incorrectly.

When I open it up on my Pipedesigner, the font is simplex. I can't figure out why it is doing so. When I open the file, it makes all opened files convert their textstyle to simplex. When I close Autocad and reopen it, it paths back correctly to the proper textstyle, architxt, until I open the file that is causing it.

The fonts that have been replaced are likely custom fonts and/or fonts that aren't installed in your computer font library. AutoCAD automatically replaces these fonts with Simplex.shx.

The first line reverts back to Simplex when exiting the TCE. The TCE allows Bold and Italic to be assigned to SHX font, even though they are not supported.

If the simplex.shx font is damaged and not displaying correctly, copy simplex.shx from a working system into the following folders.

Find the path to the acad.fmp file in Options > Files > Text Editor, Dictionary, and Font File Names > Font Mapping File.

If your drawing specifies a font that is not currently on your system, the font designated as your alternate font is automatically substituted. By default, the simplex.shx file is used. If you want to specify a different font, enter the alternate font file name by changing the FONTALT system variable. If you use a text style that uses an Asian ...
