Trying to do an Escher football, and a script to measure the angle between two lines would be handy.

Is there such a script?

Hi Brian, not that I know of currently.

If you position the x-axis of the construction plane along one of those lines and then draw a new line snapped on to the other one's end the angle readout in the bottom toolbar would tell it to you, that shows the angle of the line as measured from the x-axis of the current construction plane.

Hi Brian, I've attached a plug-in command that can be used to measure angles.

Unzip and copy both files into the \commands folder and then there should be a new command named Angle available that you can set on a keyboard shortcut (I knew you know that, just mentioning for anyone else....)

I've only really quickly whipped it together so it probably should be tested a bit to make sure it works ok.

Thank you Michael. That was quick.

(I was thinking some of the math from Bisector script would be relevant...)

Edit: Looks like it can do complementary angles too, with heel to toe lines selection.

And the beauty of the thing is that you can only take 4 points of anything :)
Not only from lines! ;)

You're welcome Brian, I hope that is useful!

Thank you, i really need this one : )

Awesome !

Usually I just draw an arc to see the angle.

Lines are not necessary on the same plan so Arc maybe not directly efficient without some Helper lines !

This is, and has been, a great script.

Yesterday and today I spent considerable time trying to figure out why a math formula applied to angle A would not achieve the correct angle B.

I forgot that the Angle script reports in degrees.

Serendipitously, another problem was solved, via the extended DeMoivres formula, nth roots of unity.
(Fractional exponents of complex numbers, require an extended formula.)

So improvements to Angle script would be to display label "degrees",
as well as option to display "radians", kind of like circle display of "diam" vs "radius".
(I'll put it on my ToDo someday list:-)

The dimension script has an angle option

You can also use the Bottom numeric Box ;)
A simple line (that you don't draw) + Helper Lines give you all the angles of something drawn you want!
