This is a great tip for performing the same functions on multiple xrefed files.

Leonid Nemirovsky sent in this tip for AutoCAD 2009. "In MTEXT windows, if you need to superscript or subscript any number of characters (for example, ABCD^45), in the Mtext Editor window, highlight ^45 and select a/b (fractional icon inside Mtext Editor) and you will have ABCD subscript 45. If you do need superscript, use this similar procedure: type ABCD45^; highlight 45^, then a/b, and you have it.

"If you have two parallel lines of equal or unequal length, the Fillet command (regardless of setting for radius) will put an arc between those parallel lines. If the longer line was selected first, it will make the shorter line the same length as the long one, and vice versa.

"To manipulate all xrefs at the same time without going to each individually, run the Xref command without a dialog box by typing -XREF at the Command prompt, and then selecting one of the options offered on the Command prompt, such as Bind, Detach, Unload, Reload, or Overlay. For example, type D for detach and respond with * instead of the xref names."

Users often need to include superscripts or subscripts. Using the ^ (caret) key before or after the text and stacking it as described will allow us to create them. There are some default settings for specific superscripts (like the number 2) but we often need other numbers.
The fillet command can be used to make one end of two parallel lines start or stop at the same distance. It doesn't make the lines the same length. When the fillet command is invoked, it creates an arch between the two lines that is tangent to both lines. The second line selected will either be trimmed or extended accordingly if the two are parallel. If they aren't, then both lines will be trimmed/extended in order to create a fillet of the given radius that is tangent to both lines. This tip will make the end of two parallel lines end at the same point.

This is a great tip for performing the same functions on multiple xrefed files. This type of interface can be accomplished with most commands and is key when creating LISP routines, script files, or button macros. Typing a dash (-) in front of a command will tell AutoCAD to start the function without a dialog box. The command will be run the old-fashioned way, completely through the command line. Many times this can speed up command entries, especially if the user already knows the sequence of keystrokes.
