Thank's Michael. How are you seeing those needle alignment issues? I zoom in and it looks fine. I set the mesh angle to 3 and I still can't see them.

Hey Luke,
I didnt see it either. I think it is a "post boolean" item. Not pre boolean

If you zoom to where your green object is "Supposed" to touch with the other object in the front view, you can see the gap that would create a tiny sliver.

I zoomed in to make that gap large enough, then selected the green object and used the edit frame to drag its size to snap the other object, then I did the boolean.

Hi Guy, re:

Yeah like Burr writes above it seems to be after the boolean.

Got another diff issue. I'm trying to diff the green screw thread with the main body to leave a female screw thread but when I diff it the entire body disappears.

Hi Guy, coiled objects like your screw thread here can be difficult due to the underlying surfaces overlapping each other from one coil to the next.

Try with the attached version, I split your thread object into 4 quadrants using Edit > Trim and then used ShrinkTrimmedSrf on it.

Thanks Michael,

Why did you have to split the thread into object into 4 quadrants?

Hi Guy,

re:

Because that removes the condition that is failing which has something to do with having underlying surfaces that overlap each other.

Hi Guy,

Another trick is to scale everything so that the size of the threaded object is around 50 units (rather than 6 mm), do the boolean, and then scale it back down.

Ahh that's easier, thank you.
