Hello here are the data : from packagesvgpathtools.svgpathtools.path import Line, CubicBezier b1 = CubicBezier(start=(10 + 110j), control1=(56 + 94j), control2=(31 + 132j), end=(15 + 134j)) l1 = Line(start=134j, end=(515 + 134j)) intersect1 = b1.intersect(l1, tol=0.01) print(intersect1)

b2 = CubicBezier(start=(133 + 154j), control1=(87 + 138j), control2=(112 + 176j), end=(128 + 178j)) l2 = Line(start=178j, end=(633 + 178j)) intersect2 = b2.intersect(l2, tol=0.01) print(intersect2)

b3 = CubicBezier(start=(35 + 151j), control1=(50 + 151j), control2=(86 + 169j), end=(64 + 183j)) l3 = Line(start=183j, end=(564 + 183j)) intersect3 = b3.intersect(l3, tol=0.01) print(intersect3)
