You can have multiple threads on a single screw like so:
It’s not much used in classical screws but you see it quite often in large diameter screw-on lids and in mechanical engineering where it can produce a double or tripple linear distance per rotation. I think drill bits have a double thread as well. So it could be a useful feature to implement!
it’s implemented in my plugin… you can make “multi-thread” profile. only thing that i have to support is unique material ID for every profile segment
But doesn’t that memory leak only matter up till the user collapses it to an editable poly object.
A VERY cool script by Denis… I guess the icing on the cake would being able to create end pieces to the threads as well (and of course screw heads, but they’re easy enough to do). It looks like the ends could be created by slicing the end, capping it, spherizing the cap face (to make it a perfect circle), centering it to the axis of the screw (ideally with a soft selection of make the transition smoother) and finally extruding/beveling it. I have no idea though how that would be scripted
that’s easy. we can add another CurveControl to control Outer Radius by height and instead of using Inner Radius use Thread … let’s call it … Depth. so the inner radius will be Outer Radius – Thread Depth.
Or just select an object you want to use as head and it will be attached automatically
These tool look cool
