Good vid but yeah way too much polycount for what i’m trying to do. I ended up moving a loop out a little and it makes it not so obvious now, i lose a bit of the sharpness but its a decent trade off. many thanks.

Hello, please share your file so that we can give a try: https://pasteall.org/blend/

Sure, here you go. If you can figure out how to avoid pinching it will help me with all the other parts i have too…

so you can do it this way:

you could use an Array modifier with Object Offset (here an empty at the center) to make the whole shape:

Yeah, that’s the way I initially did it but I think mine was too low poly. So the answer is more poly.

Thank you for your help, If it’s not too much, would you take a look at this one too? I posted it a few weeks back but had no replies.

Basically I need to combine these two cylindrical shapes but I cant avoid triangles which is causing…pinching. I’ve been trying for ages to eliminate triangles but die to the way the cylinders meet, I’m not sure there is a way.

Understand if you dont want to, it wasn’t the original question after all, but here’s the blend file just in case. Many thanks.

edit: Im’ giving a try

I did a concept mock-up for a car and this part was the rear wheel arch.

probably needs some adjustments but seems to work fine this way but I redid it from scratch (with two 32 vertex circles, but you can delete some edge loops once you see that they are useless). The file here.

Hey that’s great! thank you for taking the time to take a look! Appreciate it.
