screw threads

Matt Maier
The last time I checked, OpenSCAD couldn't automatically generate any kind of helix. Is that still the case?

Is the MCAD library still the best place to go to get started with generating threads for nuts/screws?

Re: screw threads

Peter Falke
Hi,

I once wrote the this little program:
It does a chain-hull of the profile. This is very fast with F5 and very slow with F6. Because the final union-ing of all the parts takes forever.

But nowadays this might be done faster with the vector append function.(?)

We should have a contest who can come up with the fastest program to render a screw. :-)

@Matt: What kind of a helix do you need?

Sincerely,

TakeItAndRun

I think my modifications can, but they are not a part of the
official release.

here are the docs, so you can judge if this is
what you are looking for:

Via scad-utils it can be done. See Helges article
