quiliro: the easiest way to get the cheat sheet is from the application; Help > Cheat Sheet.
<JordanBrown>
I don't see any JavaScript in the cheat sheet; it looks like vanilla HTML and CSS.

<quiliro>
why does it give me an error? I tried with semicolon after abs(y) also.
<peeps[zen]>
too many open parenthesis
<J23k>
quiliro have you tried counting parenthesis? also the build in editor will highlight the corresponding bracket if the cursor is near .. using spaces can help spotting these mistakes easier

just always set them in pairs so the moment you open one - close it and put your input between - so you don't forget that you opened it.
<quiliro>
OK...good suggestion

I have https://termbin.com/obul . It is a square pulled by the corners to form a catenary. I need to make a structure to make it keep it stretched that way. Which form should the frame be?
<quiliro>
a structure to keep it stretched that way *

I want to make a frame to keep it streched. How should it be?

i gave you the module to use an extruded polygon why you are not using it?
<quiliro>
It is too complicated for me
<quiliro>
let me check
<quiliro>
I cannot find the version where there was an extruded polygon
<quiliro>
if you pull a sheet of paper from all 4 corners but they are not on the same plane, you get a catenary

i think if you had paper like that, and look from perfectly vertical, the outline would no longer appear as perfect square/rectangle, due to some of the length of paper taken up by vertical distance
<peeps[zen]>
is that the issue you are trying to solve?
<peeps[zen]>
what i mean is that the length of the catenary curve needs to be fixed to the length of one side of your sheet
<peeps[zen]>
so you may need to do some complex math to determine the actual catenary curve which results in that specific length
<peeps[zen]>
either that or I think the sides of the paper may need to have a slight curve or something cut into them to produce a square projection when viewed from above
<peeps[zen]>
quiliro: so you are mainly using openscad as a visual aid for your manual construction?
<peeps[zen]>
the end goal is still just unclear to me
<peeps[zen]>
or, how openscad fits into your process exactly
