I'm assumning you are talking about flowlines.
Goto Tools-Application Options-Solids there check Draw Flowlines and press the default button. I think that is the bahavior you want. You may also specify the number of flowlines for the individual surface types. Then press OK to save the settings.
For solids already in existens in a file you can go to the solids menu and select Modify-Modify Flowlines set settings and selecte the bodies to be modified in regards to their flowlines.
Hope that's what you are after, Hans
