Blender : Modelling with cross sections By Toussaint Frédéric Translated from french by Saraja Olivier

Just as we saw before, the surface doesn't go up to our last curve. This can prove annoying during with fine modelling, so Blender has a function that helps correct that. Go to the edit buttons window  and enter the edit mode (TAB-KEY). Select with the B-KEY the highest curve of your object and the push the  button.
