Hey guys,

How do I model a realistiq nut and a bolt, with a nice helical ridge...?

Thanks !

CTRL+X , to model a nut and a bolt is something very simple... that damn helical ridge is the problem... :)

Jockomo... thanx ... exactly what I was using ... but there's not what I wanted... the ridge... :)

i believe that the ridge part IS covered by the tutorial. it's on the LATHE tool part


Threads, a nightmare...or maybe not?

Let's take a closer look.

Make a small triangle just below the bolt.

18: Next is the lathe tool, and now it's time for some calculations. Since we are so lucky that we're using LighWave 3D, we also have a built-in calculator....

Let's say that we want to have 35 rounds of threads. With a smoothness of 24 sides per revolution, we type in 24*35 in the "SIDES" field in the numeric panel.

Since we want 360*35 the "END ANGLE" automatically calculates this to be 12600.

Play a bit with the offset and press the spacebar when you're satisfied.

Note: It'simportant that you don't cover the whole body of the bolt with threads as this is highly unusual.

19: Inverse the layers, putting the threads in the background layer and do another boolean substraction.



you just have to tweak the start shape if a simple triangle doesnt' fit your needs
