I was creating a jar.
1st effort: started at 0,0,0, went over 2 in X, then up 3 in Y, then back to 0 on X. added revolved node, all good so far. added convert node to get polygons, good so far but when I went to select face I could not select any faces on model.

second effort: I started at 3 in Y and 0 in X then go over 2 in X, down 3 in Y, back to 0,0,0, revolve, convert, it works just fine I could select faces.

what gives? after everything the model in first example was blue in view port, while it was white in second example. I am assuming I had reversed normals in first example? so does it matter in Houdini which way you run your curve to select faces?
