Yes and no. Here's a quick and dirty ploy using Line. It doesn't
produce the nice smooth curves that ParametricPlot3D does, but it
produces recognizable wireframe drawings.
f[x_, y_] = x^2 + y^2;
m=Table[{x,y,f[x,y]},{x,-1,1,0.1},{y,-1,1,0.1}];
m1=Map[Line,m];
m2=Map[Line,Transpose[m]];
Show[Graphics3D[{m1,m2}]]
