Hi,

I’m a new Shapr3d user and don’t have any cad experience. I’ve been practicing on my own a bit and tried recreating my own version of a knob. So far I haven’t been able to figure out how to replicate the bottom of the cut out grooves. I want them to be round as well, any help would be appreciated!

Select the edge at the bottom of the groove and use the fillet tool. It should go to the fillet tool by default once you select the edge.

Yes, as **[Oregonerd](https://discourse.shapr3d.com/u/oregonerd)** wrote , fillet this edge

To make this kind of form…

I think circular pattern of capsules will work better 🙂
