Topic: Getting the angle ...

[Hangman]

How can I get an angle of two defined points ??

an example:

Code: [Select]

(setq A (getpoint ... ))
(setq B (getpoint ... ))
(setq ang1 (getangle A B))

This gives an error as getangle is waiting for user input.
I can't give user input to get the angle.  Any ideas to get this angle ??

Thanks.

Perhaps try

Code: [Select]

(SETQ A    (GETPOINT)
      B    (GETPOINT)
      ang1 (ANGLE A B)
)

getangle...
asks you for two points or a numeric angle

just to clarify Jürg's post, try these ...   

Code: [Select]

(setq ang2 (getangle "\nSelect 2 points"))

(setq ang3 (getangle "\nEnter decimal degrees to convert to radians. "))
and compare them with the previously posted functionality.

Thanks Kerry,
early in the morning after a birthday party :doa:
I was not in the mood to write a comprehensive explanation...

Thanks Kerry.  Now that you've mentioned the

(SETQ A    (GETPOINT)
        B    (GETPOINT)
        ang1 (ANGLE A B)
)

I have found this all reference all over the place.  I'm a blind draftsman.   

Anyhow, my sitiation is that I have two points from a previous creation.  So I can't ask the user to pick the two points for the angle.  Your post was most helpful.  Thanks again.
