unfortunately not that much success, can you do a run through of how you did that

Try sharing a file because I honestly can't make much sense of your dimensions.
A 150mm [diameter?] with a 20mm height seems wrong.
-
its a screw on cap, the dimensions are correct
-
if you look at the pictures I posted you can see the height of the thread

pitch 2.7 mm
I expect your first problem is you are measuring the pitch incorrectly. From your images it looks like the pitch is closer to 5mm.
So far you haven't told us what your actual problem is in modeling these threads. I've shown you before how to model screw threads. The process is the same with these. Start with a helix and profile. Use Upright Extruder.
The method Rich described will work fine, too.
-
Are you trying to model a cap or the neck of the container? What is it exactly? I've been trying to find real specifications for the threads on screw top containers but based on what little information you've provided, it's been a waste of time.

this thread is a weird one . its on an Italian built mega yacht. its a 150mm diameter aluminum tube with a 20mm high thread on the end. the tube holds a retractable electric cable for shore plug in, when at sea the cable is retracted and the cap I have to make screws on the top to keep the water out
I"ll get some more info on the thread -
here is the profile and my measurements, there are only 4 crests on the thread
hope this helps -
with a 150mm diameter

So what's your problem in trying to model it in SketchUp? What's not working?

When you model it make it 2 or 3 turns longer so you can cut the extrusion off nicely. -
I’m the problem, ha ha
I need a back to basics tutorial, I always seem to miss a certain point and nothing happens . I can see the way both of you do the threads but I’m missing something -
with a 150mm diameter

ok , after watching Rich's video about 8 times I'm making progress. I was missing the upright extension
what's curve origin? I set it to -1.5 as in the video, so that made the male thread , now to make the female which ill offset by 0.3 -

OK. So you don't need the video tutorial I did? Good enough.
-
@Dave-R where is it?
