Hello all, this is my first post on these forums and I'm a fairly new user of AutoCAD. I've been using the dynamic input field(s) often but have often felt the urge to input some simple mathicmatical equations (264-39 for example when extending a line) but the program won't take it. It has worked on very rare occasions but I have no real clue how. Is there any way to ensure this works to make AutoCAD know it's supposed to handle the input as an equation instead of a sole value? Thanks In Advance :) |

You can directly use integer division ("/"). For other expressions you can use the AutoLISP notation - e.g.:
(- 264 39)
(* 6 7)
(/ 22.0 7.0)
(+ 1 2 3 4 5)

| It does appear to work, but I wonder why it will recognise a division but nothing else? Doing it with the AutoLISP notations is quite cumbersome :( |

The data entry doesn't support expressions - the division only comes from the fraction data notation. But LISP expressions are quite easy - all must be in round brackets, first comes the function, then its operands. ------------- Vladimir Michl (moderator) ARKANCE - https://arkance.world" rel="nofollow - https://arkance.world - Autodesk Platinum Partner |

Thanks, it's easier to understand written in English. Brackets -> function -> operands... cool!
