Editing Macro Files
Arbortext IsoDraw stores macro files in ASCII text format. You can use a Windows text editing program to edit the macros in macro files.
* 
If you use a Unix text editor, make sure to save the file with Windows-compatible CR-LF line breaks.
When you create a new macro file, save it in the folder Arbortext-IsoDraw-install-path\Program\Macros with the file name extension *.ism.
