CS NumInText
Description
You can use the add-on application NumInText to perform operations on numbers written inside AutoCAD drawing objects - texts and block attributes. It works both on purely numerical texts and on numbers contained in longer texts and MTexts. You can round the numbers (also in non-standard steps like 0.5), add (or subtract) constant values to them, multiply (or divide) them by a constant value, left- or right-fill them to a fixed number of digits, cut off higher orders, or delete the numbers. The application can also handle numbers combined with MText control codes.
