    I don't have SolidWorks with me right now, but try this:
    Set the background in solidworks to "pitch black". It is one of the default scene settings. This will make it very easy to spot any open gaps in your model, as they will be a light shade of blue.
    If the knit tool is not making a solid, you have a gap or hole somewhere.

    You can also try exporting your surface data as an Iges file and reimporting it. sometimes the model will stitch together a little different, and you can end up with a solid model (minus a feature tree).

    Two gaps are in your model. See attached screenshot. To see the blue edges, you also need to be in Shaded with Edges mode.

    Nice job for a SolidWorks 2011 model! I was able to repair the model and make a solid body, but the tools I used most likely did not exist in the 2011 release. I can send you a parasolid model, but you'll loose the feature tree.

    Thank you very much. I find problem by your image and fix it. So now I have full solid body. But I still need to do shell from it. Because it will be very expensive if I print full solid car.

    Problem is: When I get shell and check bottom of the car write me error massage:

    " Thickness value is greater than the Minimum radius of Curvature. The shell may succeed, but could cause undesirable results, such as bad geometry. To find the Minimum radius of Curvature, use Tools, Check."

    If i click OK, then show me some parts (maybe that parts are wrong), but I have no idea what is wrong with them and how to fix it.

    Please help me If you know what is wrong and tell how to fix it, or send shelled that solid.

    Thank you very very much.

    (I add solid car)
