Knurl

I used AutoCAD 2004 to produce these solids and for the rendered image. The surface material was created using AutoCAD's 'Modify Standard Material' feature.

Expect more spiral solid things.

Very realistic. Nice job.

Hi
On the face of it, it looks quite simple but I can appreciate how much work has
gone into producing it.
I like the mirror effect.
Cool

Nice rendering.
Was the knurled part, modeled or is that where you were manipulating the materials? bumpmap?

[aledtaylor79401]

The knurled part was modelled. Only the mirror finish was accomplished by manipulating the materials.

I’ve posted an explanation of how it was done in the AutoCAD 3D forum ‘3D Diamond Knurl Surface Finish’.

I've attached a drawing of a 10mm diameter knurl segment. Use the mirror command to make it longer.

Very well done. I especially like the mirroring on the knob. That must have taken some doing.

[aledtaylor79401]

The mirror finish took some experimentation with the material settings.

I’ve attached a file with the material.

I hope you’ll find it useful.

haven't checked the material file, but my applause to you as I have yet to figure out how to do a mirror finish in AutoCAD. so you did the knurl segment separately and then arrayed it around the shaft? I've done that in MDT but with 3d helix paths and was never able to render it w/out my machine conking out. nice job!

[aledtaylor79401]

so you did the knurl segment separately and then arrayed it around the shaft?

Basically I extruded a triangle along an elliptical path to create a 'cutting tool', arrayed this around and then subtracting them from a central solid. Check out the link for further details.

Nossa, que legal .... esse desenho ajudou muito. Obrigada!!!!!!
