threads.scad errors
hi,
trying to generate a large (25mm) screw, 9mm long, with a decent (between
the U.S. "national coarse" and "national fine") thread count.
if i use:
metric_thread(diameter=25, pitch=26, length=strsScrewLength, internal=false,
n_starts=1);
it fails (see below);
if i use:
metric_thread(25, 16, strsScrewLength);
it works.
if anyone has any advice, i'm all ears.
thanks

I get the OP's errors with 2014.03. And with just the metric_thread(25,26,9)

OK, the library, where the pitch >= diameter, gets n_turns=0, probably not
healthy.
It may take a while to understand what's happening.
Perhaps, diameter=25, pitch=24 will do???
