Because you gave it triangles, which are 2d connections (surface) although imbedded in 3d in your case.
Isosurface gives surfaces (triangles -- 2d) if you give it a 3d grid; lines (1d), if you give it a surface; and points (0d), if you give it lines -- polymorphism at work... Does your 3d data have a grid? If it is scattered or point data (i.e., why you used Connect), then I would suggest you use Connect with the tetrahedra option (assuming it's in the version that's available) or Regrid (or AutoGrid) to create a 3d grid for your data.

Apologies for the message size but I figured including the print info would cut down on traffic overall. I have a 3d dataset (type general) with one data field (4 columns). With glyph it plots nicely in 3D, with glyphs colored/sized by data magnitude. I'm trying to get the data displayed as an isosurface (volume) instead of glyphs. The basic net ?I'm using is: import -> connect -> isosurface -> autocolour -> image -> print The print output is below. The image is a set of contours, not a surface. How do I get it displayed as an isosurface? <output from print after passing through connect as above> Field. 5 components.
