Hi, I'm in the F1 In Schools program, and my teacher has 1Solidworks 2009 program installed on it. Whenever I fit a lidperfectly in the hole, it still says that the geometry isincorrect. Please help me, I followed the tutorial, except when itsays to make all the car except the lid red, the Appearence Managerdoesn't open (After I apply the color, the"edit-the-properties-of-appearence" panel). Please help, I needFloworks to work!SolidworksFlow Simulation
