# Why Strange extra vertical lines appear in eps format of ParametricPlot and how to remove them?

Using the following code, we can generate the parametric plot of func1 and func2 as a function of r:

    func1=(104832. r^9 - 70560. r^10 + 8064. r^11 + 4368. r^12 - 1444.8 r^13 +
168 r^14 + 8 r^15 + 0.149718 r^16)/(32 \[Pi] r^15);

func2=(128 r^15 (29484. r^2 - 13230. r^3 + 1134. r^4 + 491.4 r^5 -
135.45 r^6 + (27 r^7)/2 + 0.00935739 r^9) -
144 r^8 (6552. r^9 - 4410. r^10 + 504. r^11 + 273. r^12 -
90.3 r^13 + (21 r^14)/2 + 0.00935739 r^16))/(11520000 \[Pi] r^15);

Show[
ParametricPlot[{func1, func2}, {r, 0, 150},
PlotStyle -> {Blue, Thickness[0.008]}, MaxRecursion -> 10]
, PlotRange -> {{.1637, .167}, {.16, .22}}
, Frame -> True, AspectRatio -> .4, ImageSize -> 400,

The resulting plot in 11.0.1.0 version of Mathematica is: (It is what I expected and seems true. Maple gives the same plot.) During plotting this curve, Mathematica gives 2 errors:

 Power::infy: Infinite expression 1/0.^15 encountered.
Infinity::indet: Indeterminate expression (0. ComplexInfinity)/\[Pi] encountered.


The problem is when I export this figure to eps format, 2 vertical lines appear which I don't know the reason (may be because of infinities) and my question is how to remove them? Try Show[ParametricPlot[{func1, func2} // Rationalize[#, 0] &, {r, 0, 150}... to force symbolic plotargument.
