AutoCAD Error: “unrecognized version and cannot be read”

1 Feb 2019 Darren Young

If AutoCAD has ever given you an error “unrecognized version and cannot be read” error, it’s likely a corrupt CTB/STB file. An image of the error can be seen below…

You can also see this followed by another error dialog, “is not recognized syntax, select OK to ignore or Cancel to abort“. This error also shown below, is likely related to the same corrupt CTB/STB file.

Where Are CTB/STB Files Located?

To find where your plot style tables are located, type “OPTIONS” in AutoCAD”s command line. In the “FILES” tab, expand the “PRINTER SUPPORT FILE PATH” node as shown below.

A few things to note and the plot style tables support path….

  • Support paths are specific to the AutoCAD profile that’s loaded. Load a different AutoCAD profile and the path may be different.
  • AutoCAD profiles are user specific, if other users log into the system, they may also be pointed to a different path.
  • Support paths for the plot style tables will follow nested folders. That is, if you have folders under the configured path, AutoCAD will look in all those sub-folders for additional CTB/STB files too.
  • Shortcuts are followed. IF you have shortcut placed in the support path, AutoCAD will also follow and look for CTB/STB files in the location the shortcut points to as well as any sub folders there too.

Don’t use BMP files for ITM Images

If you’ve been using an Autodesk Fabrication configuration for a long time, like back before Autodesk acquired MAP Software Ltd, you may have a lot of content that’s using Bitmap (*.BMP) files. These image files are used on a couple key locations….

1: Service Palettes….

2: Folders Dialog….

If you’re Fabrication configuration uses BMP files for images, you should consider converting them to PNG files. There’s a number of utilities that will do this in bulk for you if you have a lot. My favorite is using TechSmith’s SnagIt Editor but there are others.

Use Windows Explorer and browse to your content. You can use the search functionality in the upper right corner and search on *.BMP to see how many Bitmap images there are. Or you can browse folder by folder looking for them. Hint: Sorting by type can speed with this too.

Once you convert the BMP’s place the PNG files in the same folder using the same name as the BMP and then delete the BMP files. Doing this will reduce the size of the files which in turn speeds the display of your service palettes and folder’s list.

Autodesk Fabrication: Best Practice #1

Don’t use Double Quotes ( ” )….Ever.

An Autodesk Fabrication Configuration contains a lot of information. One of the best tools for managing, sorting, filtering and maintaining lots of information is Microsoft Excel. There are some functions in Fabrication that export information into CSV format. Commands like SYSSCRREPORT in CADmep. You may even have some scripts or API code that exports data to a CSV.

When Double Quotes are used, this can and does often confuse Excel into thinking that it’s a separator between multiple pieces of Text and it can shift the data in some rows to different columns.

If you use feet-inch format/units and like the look of double quotes for inch marks, an easy workaround is to use 2 single quotes ( ” ) as opposed to a single double quote ( ” ). When using 2 Single Quotes, it’s hardly noticeable even when looking for it like in this text. Try selecting the text sand you’ll see they are indeed different.

While this rule should be adhered to anywhere in the fabrication database, there’s 4 primary areas where it’s most likely to cause you grief.

Database Entries – Materials, Specification, Connectors, Seams, Airturns, Ancillaries, etc.

Folder and ITM Names – While a perfectly valid character in Windows for files and folders, it’s not a good idea when using Autodesk Fabrication.

Product List Names – One of the most common areas to see the inch mark.

Product Information Editor – Another common location where you’re tempted to add double quotes. It’s common for people to maintain this data in Excel in the first place so it’ll be really easy to do a global search and replace to fix it.

In future posts, I’ll share some processes and scripts that can be affected by using Double Quotes. Until then, just trust that it’s a bad idea.
