Hi All,
Been a while since ive needed any help but im stuck. Im need to create a curved cylinder part to connect a flat piece to a tube that is at an angle. Im using the follow me tool but for the life of me i cant get it to work properly so the 2 marry together. Can you please show me how to do it.
Thanks Dan.
Attached is the file. Hopefully will make more sense when you open the file.

I’m not seeing where you are trying to work. Can you show a screen shot or an image of what you are trying to model?
BTW, there’s geometry around the hole shown here that prevents the base from being identified as solid.
Nice work on the threads.
So you want an elbow between the top tube with the threads and the flat base?
What I see in your screenshot shows you just need to change the arc for the path. The first and last sements in the path need to be perpendicular to the desired ends. When I need to do this sort of thing I use a circle and rotate it so the end segments are perpendicular to the start and finish. Draw the circle and then rotate it as needed. Here I intentionally use a 24-sided circle so the sides are visible in the GIF.
I placed the tube with the threads angled at 45°, copied the bottom face of the tube out of the group, pasted it in place and used it as the profile with that path.

Thanks Dave, ideally I want to keep the threaded part where it was at the angle it was so will the same technique work?
Yeah. You’ll just have to figure out where the center of the circle/arc needs to be when you draw it. You’ll need to make the path radius slightly larger than the radius of the tube to avoid weird twisting of the geometry at the inside of the bend.
Think ive done it. So best way is draw your circle, rotate it and use an angle that falls on the mid points of segments in the circle, set the angled tube to that same angle the all lines up nicely.
Yes. Or you have to add straight segments at the ends of the arc that are perpendicular to the desired ends of the extrusion.
For the screenshots of the final thing in both cases I used a 96-sided circle and 45° bend but if you need some other angle, just use a number that is a multiple of 360° divided by the angle.
Great thankyou.
