1 year ago not exactly the same problem, but I had trouble using hull today with this example:
out = cq.Sketch().circle(rod_d / 2 + wall_t).push([mount_loc]).circle(mount_d / 2 + wall_t).edges().hull()which is basically a big and small circle that intersect each other. using hull produced this error:
Traceback (most recent call last):

sk = cq.Sketch().circle(rod_d / 2 + wall_t).push([mount_loc]).circle(mount_d / 2 + wall_t).edges().hull().reset().circle(rod_d / 2, "s").push([mount_loc]).circle(mount_d / 2, "s")

dx /= l
ZeroDivisionError: float division by zerowhere l is basically the distance between the objects.
After messing around a bit, I solved my issue (without understanding the code too much, just messing and observe what works) with this commit. Possibly this could help you.

To Reproduce
I was going through the Sketch tutorial, and playing around with hull(), and encountered this error. What am I doing wrong in this script below?
This is the model right before the
hull()invocation above:Backtrace
