Your formula only works for one case. The following works for all cases:

hinge := (readable(owner));
hinge.geom1 == 0 ? {
_hingeAbsolutePos = hinge.geom1pos
} : {
g1 := (entitybygeomid(hinge.geom1));
r = math.vec.dist([0, 0], hinge.geom1pos);
a = math.atan2(hinge.geom1pos(1), hinge.geom1pos(0));
_hingeAbsolutePos = g1.pos + [r * cos(g1.angle + a), r * sin(g1.angle + a)]
}

Thankyou ill try it
