There are several ways you can break your drawing and cause GunnShow to fail to export the network. When you get an error like this on export…

…unfortunately, the referred-to error log file doesn’t function in the current versions of GunnShow. We have disabled the log feature because it causes large networks to take too long to export. So you have to debug the problem the hard way. Here are some of the possible causes to look for:

• Duplicated or missing node numbers. For example, if your nodes are numbered 0, 1, 1, 2, 3 (1 is duplicated) or 0, 1, 3, 4 (2 is missing), you’ll get this error.
• A Jumper link that points to a Socket List that doesn’t exist will cause this error. If you remove or rename socket lists, be sure to update any jumpers that use them, and make sure the socket list names in the Jumpers’ shape data are spelled correctly.

If you find any other causes of this error, please let us know so we can update this list!
