typing in Pi |
|
|
Is there a fast key code to type in the value of Pi? ALso when trying to
draw a line at an angle of 1/4 pi radians , how would you type this in -
so far I know how to to specify whole values such as @2<2r but when
trying to type in a fractional pi value I'm getting a syntax error

!pi returns the value of pi to the command line.
....or use lisp expressions: (/ pi 2.0), (/ pi 4.0), (* pi 1.5), etc.
However, you can't use these formats in a command string with the @
function. When working in radians, you can specify decimal values only, for
example, @2<2.123r. If you're working in the common fractions of pi (1/4,
1/2, 3/4, etc.) it may be easier to just use degree notation and use 45, 90,
135 respectively.

May I remind you, also the value of 355 divided by 113 is approximartely |
accurate enough within most calculations when you are handicapped by the
very basic electronic calculator without scientific features. And this rule
of thumb is very easy to remember, too. |

why not just remember 3.14159. in reality 3.14 should be close enough for |
any typical layout (except a machine shop, maybe) |

You needn't remind me. I've only known that relationship for 50 years or so.
Perhaps the OP would appreciate the information, but since he was asking
about AutoCAD, it's a bit off-topic. Besides, "!pi" takes fewer than half
the keystrokes of "355/113" -- and returns a far more precise value.

another way is to open the Windows calculator, set it for sci. mode and hit |
pi. it gives a 32 digit number.
