>From the docstring for readshapefile:
A tuple (num_shapes, type, min, max) containing shape file info
is returned.
num_shapes is the number of shapes, type is the type code (one of
the SHPT* constants defined in the shapelib module, see
http://shapelib.maptools.org/shp_api.html) and min and
max are 4-element lists with the minimum and maximum values of the
vertices. If ``drawbounds=True`` a
matplotlib.patches.LineCollection object is appended to the tuple.
So, you are trying to add the tuple result rather than the line collection
that you have. That said, because readshapefile draws to an axes anyway, it
should already be adding the collection to the axes anyway. Try printing
out the type of the last element of the returned tuple. It should say that
it is a Line3DCollection type, because the Axes3D object should be
converting collections upon being added internally.
I should also note that at this time, mplot3d only supports linear
projections (I am currently working on a fix to support non-linear
projections, but it is still limited to rectilinear coordinates). Also, I
have never actually tried mashing together basemap and mplot3d, so if this
works, let me know!
Cheers!
