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?

Thx everybody...XD

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.

Ok... I drew it...Thx for Nestly and Jack... Thx all guys...^.^

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?

You're right, midpoint wont' work all the time. curious that I just happened to throw an angle on there that did work. hmmm....tangent is by far the better option. gotta overlook me this morning, under the influence of decongestants.
