Hello,
I´m wondering if the combination for drawing a circle out of radius + tangent + point is missing.
See the example (that´s the goal). How do I draw the 2.23 mm radius? I know the radius, one point (at the slot opening) and I know it´s a tangent to the line that goes up.
So far my drawing looks like this:
I tried all different circle option but I did not find a solution. I guess this problem is quite easy but I just don´t get it.
Can you help me?

Re: Circle: Radius + Tangent + Point
A circle with radius R that is tangential to a line has its center R units away from that line:
-> Create a parallel with distance R (2.23) from the line. The center of the solution must be on that parallel.
A circle with radius R that goes through point P, has its center R units away from that point P:
-> Create a circe with center in P, radius R (2.23). The center of the solution must be on that circle.
The intersection between the parallel and the circle you've constructed is the center of your solution:
-> Create a parallel with distance R (2.23) from the line. The center of the solution must be on that parallel.

Re: Circle: Radius + Tangent + Point
Thanks a lot.
Guess I wouldn´t have found this solution without you.
Do you think that this is worth a "feature request" to have one more circle option?

Re: Circle: Radius + Tangent + Point
Yes, why not. This is really the one combination that is not covered currently (tangent, point, radius).
