We can plot several lines with ParametricPlot, ParametricPlot3D - see
*** below

?ParametricPlot
"ParametricPlot[{fx, fy}, {t, tmin, tmax}] produces a parametric plot
with x and y coordinates fx and fy generated as a function of t.
***ParametricPlot[{{fx, fy}, {gx, gy}, ... }, {t, tmin, tmax}] plots
several parametric curves."


?ParametricPlot3D
"ParametricPlot3D[{fx, fy, fz}, {t, tmin, tmax}] produces a
three-dimensional \
space curve parametrized by a variable t which runs from tmin to tmax. \
ParametricPlot3D[{fx, fy, fz}, {t, tmin, tmax}, {u, umin, umax}]
produces a \
three-dimensional surface parametrized by t and u. ParametricPlot3D[{fx,
fy, \
fz, s}, ... ] shades the plot according to the color specification s. \
***ParametricPlot3D[{{fx, fy, fz}, {gx, gy, gz}, ... }, ... ] plots
several \
objects together."

As you see we can also plot several surfaces with ParametricPlot3D, but
we can't mix lines and surfaces.
