Can I change angle units from degrees to radians?

Actually, by default Rhino uses a mix of units for measuring angles. Try for example creating a line to:


One does not get a 90° line. This is inconsistent!

Also, sometimes I would like to quickly copy angles to or from applications that work with radians. Being able to switch all angles to radians in Rhino would make life easier.

Hmm yeah, I see… I’ve never run across that but I tend to agree, input ought to be in degrees everywhere. I’ll add it to the heap. Thanks for pointing it out.

Thanks, Pascal!

If there was an option to switch angle units from degrees to radians, that would be highly appreciated as well. Though I understand, if I am the only one ever requesting this in the life time of Rhino, then priority will be very low. :wink:

Hello - You can do that now by typing in ‘radians’, but you do have to specify

e.g. Line 0 r<asin(1)radians

That may be enough… But the buglet that I see is that the number coming out of asin(1) is in radians and actually maybe that is perfectly fine, it’s just that the command line has no context (that I know of) that would accept radians ‘tout court’ , without the units specified.


Surely you mean:

Line 0 1<asin(1)radians

Anyhow, this is a nice solution for that issue! What remains:

Is there any way to get the Angle command report angles in radians?

(to copy them to another application)
