This tip provides a text object calculator that is used for performing basic numeric manipulation of text (and Mtext) values in a drawing. To use Numeric Manipulation of Text Values in a Drawing, load the LSP file and then run the Mmath command function. You will be asked to locate three sets of text/Mtext objects in the drawing. The first and second sets will be used to replace the values in the third set by going through each member in the first and second set, applying the desired math operative, and then placing the result in the associated text object from the third set. You must select the same number of text/Mtext objects for all three sets. This calculator is very handy when updating a table of numbers. Operations available include the basics: addition, subtraction, multiplication, and division.
