tikz에서 윤곽을 변형하는 방법

Question

A를 따라 곡선을 K까지 가장 오른쪽 상단 지점과 연결할 수 있는 방법을 알아내려고 노력 중입니다. 즉, 플롯의 오른쪽 부분에 원이 조금 더 남아 있기를 원합니다. 지금은 K를 따라 H(...)까지 직선이 있지만 K에서 H(...)까지의 곡선이 조금 더 선호됩니다. 어떻게 해야 하나요? 또한 - 점 위에 또 다른 작은 반원(예: x=-1.5, y=.2)과 x=-1.5, y=.2 아래에 작은 반원을 원할 경우 이를 망치지 않고 이를 수행할 수 있는 방법이 있습니까? 영상? 감사해요! 지금까지 나는 다음과 같은 것을 가지고 있습니다(정확하지는 않지만 유사합니다):

그리고 이것이 내가 찾고 있는 것입니다:

Answer 1

단순히 포인트를 통과하도록 경로를 변경했습니다.(45:\bigradius)

let
        \n1={asin(\gap/2/\bigradius)},
        \n2={asin(\gap/2/\littleradius)}
        in (180-\n1:\bigradius) -- (-180-\n2:\littleradius)
        arc(180-\n2:-180+\n2:\littleradius)--(-180+\n1:\bigradius)
        arc(-180+\n1:-45:\bigradius)--(45:\bigradius)arc(45:(180-\n1):\bigradius);
