VIEWTWIST > 2 * pi ? Yep

[JamesMaeding]

Just found a sheet where the viewtwist of a viewport was greater than 360 deg!

Command: (GETVAR "VIEWTWIST")
12.1987

 The number here is radians, so way more than 2 pi.

I assume negative values are also acceptable to a dwg.

The end result being all my functions that check viewtwist need to "normalize" to between 0 and 2pi.

Something new....

Yes, you can "normalize" the angle (ang) by (rem ang (* pi 2)).

[SeeMSixty7]

if you find that it is greater than PI, then simply use

(rem viewtwist (* 2 PI))

The result will be a value less than 2PI but represents the proper radian value.

Good luck

of course your code is one line and mine is like 7 🙂

yes what @john.uhden said. LOL.
