How to draw a circle connect with a arc and 2 straight lines?

[Rock er]

I'm suffering to draw a circle connect with a arc and 2 straight lines for almost an hour ago.
I'm an autocad begineer without anything tutor.
Hope somebody can resue me.
Thx.

Circle > 3P (3point) perhaps?

Use the CIRCLE command, with the 3P (3point) option, and a TANgent OSnap to create the red circle in the following screencap

Try this. Start the circle command, then enter 3p.

Nestly, you were quicker on the "draw" than me....lol...get it...the "draw"...ok, so it wasn't all that funny.

I used midpoints and near instead of tangent but it did the same thing.

Glad to help, Rock er

Well, Jack, I had a headstart since I was already subscribed to the thread. (wink)

I'm not sure about the MidPoint option, inner circle would only be tangent to the other 3 objects at one very specific included angle, right?
