Hello,

I am a total newbie in Sage and I do not talk Python :-( I was just trying to draw some surfaces for illustration when I came across a problem loading my saved computations.

NotImplementedError: You must override the get_grid method. (code below.)

Is there a way to do what is suggested (override...)?
I found a bug ticket http://trac.sagemath.org/ticket/9957 and saw http://ask.sagemath.org/question/7704/importing-saved-3d-plot/

I am not very hopeful, but since I basically do not understand what's written, maybe there's a way to override get-grid as the error message says. Is there?

If not, is there a way to convert to an object that can be saved (and at least displayed again) or export it to an external format?

Thank you,

code:

sage: pam2=load(DATA+'pam2imt5000.sobj') sage: type(pam2) <html><script type="math/tex">\newcommand{\Bold}[1]{\mathbf{#1}}\verb|<type|\phantom{\verb!x!}\verb|'sage.plot.plot3d.parametric_surface.parametricsurface'>|</script></html> sage: show(pam2) Traceback (most recent call last): ... NotImplementedError: You must override the get_grid method. sage: load(DATA+'pam3imt5000.sobj') Traceback (most recent call last): ... NotImplementedError: You must override the get_grid method.
