Good Morning,

I've been battling with this model I made it's a small electric automobile and it's the first time I really get into surfacing in Solidworks.

I have no errors in any of the feature on the tree but yet when I try to knit the whole thing I get errors, and what I can manage to knit doesn't

work with the thickness command. I get an "unable tot hicken surface" message. If I check the sketch I can see several "open surfaces" but have no

idea how could this happen or what is it exactly. All surfaces are referencing a previous one so they should all be coincident and closed.

Attached is the file in question I appreciate in advance any help you can give me, as I need to thicken this and scale it down for 3D printing!

Thanks.
