This is certainly a really basic question, but to explain myself I am certainly going to make this more complex than I need too.
I wanted to 3D print a ‘nut’ with a thread which I have no skills to draw… But I found a design that had the thread I need which looked like this:
I cropped off the bottom, giving me the thread I need:
And my plan was to ‘wrap’ it in hexagonal cylinder to make the walls, like this:
And as you can see, I did it… Except tly the hex the thread isn’t exactly in the middle of the cylinder, because couldn’t work out how to ‘click’ the mid point… Instead I just had to pick a point which was near the centre… It i will do for this application, but I would like to learn how to do it accurately.
When I imported the model, the Blue axis passed through the centre… So I just need to click on that line at the height of the model, and I can’t work out how to do it… Like this:
The crude red arrow should show where I am trying to click… But I can’t find a way… How do I draw something from that very point?
I hope you understand what I am asking and look forwards to your thoughts
