Hi Forum. The attached shape needs two 57mm radius arcs each connecting it's line with the point and those arcs should appear to blend with one another. My methodology which may be useful was to try to draw an arc through the point, but was unable to get arc on point and line simultaneously. Tried the the same with circles...Feel like tangent feature of arcs and circles should be helpful but can't get to work with point. Thank you.

Can you sent an schematic image of what do you want ?
Seems an arc is not a line...but i am waiting your schema :)
this ? just trim the left parts... but i am waiting your schema :)

I've crudely drawn a schematic. Radius of two arcs should be 57mm and they should blend into one another. Thanks for replying.

Hi,
is this what your trying to achieve.
Cheers,

Something i don't understand : on your first file vertical distance between curve is 51...mm

else about your previous draft a little thing ;)

Trim a part of your curve, then select the little and left top big part
And use Blend ;)
Not shown : there is a glider for the bulge!



Barry solution is cool but from the first post...so waiting your answer :)

Hi Sven, Barry has the right solution above (thank you Barry). Just in case it's not clear it's done by creating this construction geometry -

A 57mm circle centered on the juncture point:



Offset these lines also by 57mm:



The intersection between the circle and the offset lines will yield the center of the arcs:



So then draw an arc from center point, put the center point onto that circle/offset line intersection, first point of arc at the juncture point and the last point at the snap point on the original lines.

The circle or arc tangent commands can do "tangent to 3 curves", "tangent to 2 curves through a point", or "tangent to 2 curves with a specified radius".

But in your case here you don't want any those, you want "tangent to one curve through a point with a specified radius".

So the circle or arc tangent commands won't help for this case but this type of "specified radius through a point" problem can be solved by some construction geometry, you first set up a circle of the target radius centered on the point.

Thank you for answers and explanations everbody. Wonderful forum.
