There are times when drawing specifications call for the use of either superscripts or subscripts, and mastering this function in AutoCAD is actually quite simple.  To add a subscript, begin by placing the “^ “ after the letter or number (also with a space after) and then simply follow the steps as presented below:

A good example is the classic equation E=MC²

1. First, use MText and type “E=MC2^  “ (with a space at the end)

2. Next, use your mouse to highlight the “2^ “ (including the space)

3. Once highlighted, select the “stack” button (b/a) on your tool bar.

4. The program will automatically create the desired end result – E=MC²
