Hello,

You can try this code with Maxima 5.14:





load(draw)$

draw3d(implicit(z=-x-y+5, x,0,5, y,0,5, z,0,5))$

draw3d(surface_hide = true,
       implicit(z=9-x^2-y^2, x,-4,4, y,-4,4, z,0,10))$

/*
Define the parametric curve:
x=t,
y=2,
z=5-t^2
*/
draw3d(parametric(t,2,5-t^2, t,-5,5))$




type ? draw for more information about this package.
