I'm using $fa

$fa = 0.01

but a circle(1) is not smooth

Chocolate: $fa and $fs work as a pair, you have to define both
<
peeps[zen]>
and it will use whichever results in less segments
<
peeps[zen]>
$fa 0.01 is very excessive though

AlgoJerViA: for code that is more than 2 or 3 lines, it's better to use a paste service
<
AlgoJerViA>
Ok, sorry.
<
AlgoJerViA>
I noticed I can fix it by using cylinders instead of circles.
<
teepee>
or extrude at the end, it's often faster staying in 2d as long as possible
<
AlgoJerViA>
I guess scaleing is not a good extrude method?
<
teepee>
it will not actually work with 2d
<
teepee>
that's just a visual effect (could be called a bug) of the preview
<
teepee>
well, to be precise scale() for 2d works only in x-y
<
AlgoJerViA>
Then I understand. Thank you.
<
teepee>
I'm not 100% sure I read you example correctly, but it might work with linear_extrude(5) offset(0.3) square(14);
