only happens to me that from a while (presumably from the last sr) extruding a polyline comes a single surface and not a polysurface? extruding a rectangle as in the example what comes from it is a single surface... as you can see the rectangle selected in yellow and the red supericie that is not exploding. Actually, it should be 4 super planes together. to have this I must first explode the rectangle and extrude the individual surfaces and then reunite them
