How do I convert from surface to a part?

Hello,

https://cad.onshape.com/documents/5cab9c8bd0c06800a23058dd/w/21f41b44ed254d01afa55610/e/7c29c9f531cc0f9dfe76bf91?renderMode=0&uiState=661944bfbb351732e9895119
I am having trouble with this CAD model of an aircraft where I want to make it a part instead of a surface. As you can see, the object is already filled at the wings but Onshape sees it as a surface. I tried using the enclose and Thicken but nothing worked as there are errors.

Thank you.

Here is the model as a part.

There was an 'open' section that was preventing the surface becoming a part.

A helpful way to locate these open areas is to extrude a surface and use it to perform a split in the imported surface and then use the enclose command to see if one side of the split will then become a solid part. By moving the splitting surface to different locations you can then isolate the offending area. (See Part Studio 2 TAB)



I hope this makes sense

Thank you so much!

There should be a diagnosis-tool to find open faces or bad surface joints in OS. That has been an industry standard for years im many CAD systems.

you can use 'Highlight Boundary Edges' but it's not always that clearly shown with a complicated open surface, (can be hard to spot)
