Add Tolerance Factor (Tip #2214) by S. Ramakrishna automatically appends tolerances based on your input to dimension objects you select. This utility is a fast and easy way to add tolerance factors and clearly shows how to use the fancy codes in text objects for your own needs. Run this utility after you create the initial dimensions in your drawing. Load the LISP code and type TL at the Command prompt. First, enter the upper tolerance factor, including the decimal. Next, enter the lower tolerance factor (don't add the minus sign, it's implied). Lastly, select the dimension objects you want to change. After you select the last dimension object, the tolerance factors are added automatically to the selection set. Nicely done! You'll find this tip very useful if you use tolerance dimensions.
