Using the intersections
library, the code would look like this (I have highlighted in red the required line):
documentclass[border=2 mm,12pt]{standalone}
usepackage{fouriernc}
usepackage{tikz}
usepackage{tikz-3dplot}
usetikzlibrary{intersections}
colorlet{bgcolor}{white}
tikzset{
overdraw/.style={preaction={draw,bgcolor,line width=#1}},
overdraw/.default=2pt
}
begin{document}
tdplotsetmaincoords{70}{180}
begin{tikzpicture}[tdplot_main_coords,line join = round, line cap = round]
coordinate (A) at (0,0,0);
coordinate (S) at (7/2,{-7*sqrt(3)/6},14/3);
coordinate (C) at (7,0,0);
coordinate (B) at ({65/14},{15*sqrt(3)/14},0);
coordinate (I) at (7/2,{-7*sqrt(3)/6},0) ;
draw[very thick] (A) -- (B) (B) -- (C) (S) --(B);
draw[very thick,name path=SC] (S) -- (C);
draw[very thick,name path=SA] (S) -- (A);
draw[very thick,name path=CIR] (I) circle ({7/sqrt(3)});
path [name intersections={of=SC and CIR, by={C,C'}}];
path [name intersections={of=SA and CIR, by={D,D'}}];
draw[red,dashed,overdraw] (C') to [bend right=-10] (D'); %to draw the curved path
draw[dashed] (C) -- (A) (I) -- (A) (I) -- (B) (I) --(C) (S) --(I) ;
foreach point/position in {A/below,B/below,C/below,
