How draw an arc (or circle) tangent to another arc and through an intersection

colekartom — Thu, 09 Nov 2017 01:38:45 GMT

Please see attached screenshot. I was hoping someone could help me figure out how to solve a problem I have. I would like to draw an arc or circle ( I can trim it later) of a specific radius that is tangent the arc that has the red cursor on it and also passes through the intersection that ends at the top green line. Any help you can give would be greatly appreciated.

Yes! Exactly! I'm sure you guessed that it's a violin.

Can you attach this fragment and specify the exact radius you need?

The radius should be 31.92. I'm not sure what you mean by "attach this fragment". Do you mean to post a screenshot again?

I meant to attach the drawing itself, or a part of it.

Ah, here you go maxim, thanks.

Withe the given radius there is only one solution (look at the attached drawing). And looks like it is impossible to meet other condition - "and also passes through the intersection that ends at the top green line"

I used FILLET command with the given radius.

Or maybe I'm wrong and the arc you want to add should not be tangent to the yellow line?

Then see the solution #2 in the attache drawing

That's great Maxim! Number 2 is the solution for me. I guess it was just a geometric solution after all. I'll try and experiment with this and see if I can learn to apply it in different areas and applications. Thanks again.
