How do I make a "fillet" in a sketch based on vertex from imported stl

ThapppThappp Member Posts: 4
I have a problem where I want to create a corner that matches the STL vertex. Here's an image. I'm new to onshape and have tried to find a solution on YouTube, but I haven't had any luck. If anyone knows how to do this, I would be very grateful. thanks!!

    A fillet by definition is an arc - an STL file is faceted, so trying to create a curve that follows "random" faceting is not a good idea. If the arc won't snap, try adding a coincident constraint afterwards.

    3 point arc?

    That's working, but I'm wondering if there's an easier way to do that. With a 3-point arc, I can't make the edge snap into the point that I marked on a vertex, and it creates a small gap.

    That's kinda working but I need to adjust it manually to get a perfect curve that's line up, but I'm wondering if there's an other way to do that.
