Some of the things I will be drawing will use threaded rod, nuts, bolts etc, and at the moment, I am just making these from a cylinder, and adding a note that they are M20 threaded rod etc.
Is there a plugin or option that I can actually have the thread visually showing?
Hopefully you can see the attachment which shows what I am trying to describe?
Creating mass amounts of tiny geometry (like modeling screw threads) will slow model performance.
If you absolutely need that level of detail in your model, then have a look over here…
(I made a box this diameter, filled a side with the texture, then scaled/positioned it at an angle. Then used the pipette to copy the edited texture and pasted it onto the column.)
