Hello everybody, i am new to this forum, i am not a physicist not a mathematician, just an architect and i have a geometrical problem that has drove me crazy. I thought to sign in JUST in case someone can help find a solution.

I am working with autocad, that means using geometry consructions all the time. I have many automatic constructions (like circle tangent to 3 elements) but I came across this problem i could NOT construct.

I ll try to describe it the best i can since i don't know the exact term in English

-I have two lines that are not parallel: LineA and LineB

-A specific point pA on lineA

-A specific point pB on lineB

I want to construct two circles (cA) and (cB) that have the same radius and

circleA is tangent to LineA, to circleB and 'passes' from pointA

circleB is tangent to LineB, to circleA and 'passes' from pointB

The final result i want to construct would be like an S connecting the two lines

I don't know if this is a darn toooo easy problem but honestly with my level of knowledge i CAN NOT solve it! As you understand i don't want to solve it algebrically

Thank you very much in advance

PS sorry if this post in in the wrong thread

ps2 i found how to atach image... 1.jpg is the problem, 2.jpg is what i want to construct, 3.jpg is the final result
