Re: if then else - possible
I found the solution========== startAngel = (startRef == "left") ? 0 : (startRef == "bottom") ? 90 : (startRef == "right") ? 180 : (startRef == "top") ? 270 : startRef,

Hi!
I have a function() where the input values are normally "top" / "bottom" and so on.which in turn results in degrees like this example
function(... , startRef="bottom", ...) let( startAngel = (startRef == "left") ? 0 : (startRef == "bottom") ? 90 : (startRef == "right") ? 180 : (startRef == "top") ? 270 : undef, r = radius,
===========Now if the variable is not "left", "bottom" etc.the startAngle value is "undef"
it works, but it happens that I would like to be able to enter degrees as a reference value.
something like
========== startAngel = (startRef == "left") ? 0 : (startRef == "bottom") ? 90 : (startRef == "right") ? 180 : (startRef == "top") ? 270 : startRef == startRef==========
Is it possible? (the last example doesn't work)
The whole function() looks like this:==========
points = circSect(0, 0, 25, [-45, 45], "top", 1, 100);polygon(points);
//
