Alessandro,

I have had success using images as bump maps to simulate threads in PW w/out having to cut them. Choose the face that you want to be threaded and apply a brushed steel or similar appearance; edit the appearance and access the advanced options; under Surface Finish, choose "From File" and browse to a file that looks like a thread (I have used the "neon.jpeg" that comes with SW as a studio texture; you can find it at ...\SolidWorks\data\Images\textures\pattern\neon.jpg). Adjust the Amplitude to your liking and check the "Use Material scale and mapping", then go the mapping tab to adjust the image on your surface.

I have attached a lo-res image that uses this technique for the base of the sink that allows it to be adjusted for height.

It might not be perfect for extreme close-ups but it should be able to add some realistic "background noise" to an image. I hope this helps.

Cheers

  Nice image Matt.
  
  I've done the same as you and I've also just used the neon stripe material as is (orientated correctly) to represent threads. Like you said. It works well as long as the threads are an obscure portion of the rendering.

    Thanks!
    
    One of the things I'm doing more of lately is creating my own bump maps to give things more texture and depth. I finally made one for the ceramic tile appearance after all these years - you can kind of see the results on the jpeg I attached for Allesandro but the lo-res doesn't really do it justice.

      Yes, bump can be essential to a more believable texture. This is one of the things I'll be showing at SW World this year.

  Hi,
  thanks for the suggestions.
  
  Why when I save the appearance edited from me for a re-use, it doesn't save the information about the texture used ?
  If I save the appearance whit the image used (texture), it save the image used for example neon.jpg, duplicating files unnecessarily.
  Why if I use my new appearance, the setting about the texture are different from the original and I need to set again ?
  How can I simulate the inclination of the thread ?
  Now I can render, as you said...with the line of the neon.jpg parallel.
  
  Thanks again,
  Alessandro

    Allesandro,
    
    Let me try to answer your questions one at a time:
    
    1) If I may paraphrase, Why does the neon jpeg get copied when you save the appearance?
    - I'm not sure... I don't see this when I save an appearance- maybe it's the setting in your PW options/Document Properties that says "Store PW data in model file"? Maybe someone else can answer this (Rob? Mike W.?)
    
    2) Again to paraphrase, why do you have to change the mapping settings when you re-use the appearance?
    - Again, I'm not sure; seems to be the nature of the beast with most of the appearances.
    
    3) How can I simulate the inclination of the thread ?
    - Yay! A question I can answer: Change the rotation angle in the "Size/Rotation" section on the mapping tab of the appearances settings.
    
    I hope that helps.
    
    Cheers

The answer to this for anyone else looking for an answer like I was, is in SW2011 there is a thread pattern under miscelaneous/patterns in the appearances pane of SW with photoview. it seems to be of a thread of about 32 threads so you have to scale it appropriatly, and it's only of a silvery materal, so any other material you need to find the png file and modify it for yourself.
Also at the moment these will not render . yay!. it's a know problem and is apparently fixed in SW2012A1 see SPR 551269
It would be really nice if SW intruduced layered textures like other rendering packages, so the colour and bumpmap were seperate. Even better if applying a cosmetic thread automaticlly applied a correctly scaled appearance which picked up the colour of the selected material
