Hello,

Took me a while and some reading but finally was able to create accurate screw threads in MoI. Helpful for connectors that require detail. The image is a 30 minute render in Thea.

What is the specifications of export file from Moi to Thea?

Pilou, maybe a .obj or .3ds as for Kerkythea?

Pilou: .obj to Kerkythea, with the "Quads and Triangles" not "N-gons".

OSTexo, do you have a link to a discussion about making the good threads? Do you have a quick explanation?
Thanks.

Hello Frenchy Pilou,

I use triangles only to export to Thea. I also used the Divide Larger than: parameter set to .2 (All) in this case. You end up with a dense high count mesh and I'm probably overkilling it but the render is so smooth, I think it cleans up much sooner than 30 minutes but I just hit run and walk away. I created an 4x2K HDR in modo using the SLIK kit and rendered it out and placed it in Thea. I used a metallic car paint preset for the bolt and I dropped an infinite plane at the bottom of the bolt to tone down the light coming up from the bottom of the table.

Hello Magic,

I developed the process with trial and error, however the threads are accurate, I think more accurate than what is produced in real life, and the procedure can be used with ISO metric and UTS. I was thinking of making a video, what do you think? I probably use more steps than required but I think the math is sound and it's better to be able to follow along. Thanks.

You've got my vote. I've trimmed sweeps from a few triangle on a spiral, but it's hit or miss.

Hello,

Will do, It should only take me about a day to produce and edit for clarity.

Hello,

It took longer than I expected but I just need to add the audio to the tutorial video, then I'll post it up.

Thank you OSTexo! Can't wait. :-)

Hi OSTexo,

Very nice thread (and render), but how do you create your accurate screw threads in MoI? TIA.

Hello,

I am finishing up the audio, I'll have it up tomorrow latest. The tutorial itself is about 30 minutes long, I'm sure there are shortcuts I'm not using, and I'm going slowly. The tutorial applies to all pitches of UTS and ISO Metric sizes, so you will be able to use this technique from the smallest to the largest of screws, bolts, threaded connectors, etc..
