Closed surface not turning into part (https://cad.onshape.com/documents/3aacefced674074e9d896a50/w/c

Hello, very, very new to onshape, I have competed a plane before and it turned into a part, but I can't quite get this one to turn into a part, by my knowledge there is no gaps, everything is closed off. For clarification I am talking about the part studio that is the very left tab. Please help me, thank you. https://cad.onshape.com/documents/3aacefced674074e9d896a50/w/c9a93895a970036a0e28204c/e/bc7148791c94b3b96d1ae71c?renderMode=0&uiState=66673ac092616752213dc943

    When I open this model up, I'm seeing a very large number of separate surfaces. I assume at some point you were trying to Boolean add them together? 

    I would strongly recommend a few things:
    - Under the view menu, turn on "highlight boundary edges". This will help you see where things are not water tight.
    - You have some extra surfaces in your model when you show all. There are copies of several parts. This will make your work more confusing. I would remove the features that are creating these surfaces, or if they are somehow helper parts, maybe delete them after you use them. Similarly you have a bunch of tangent references which are cluttering things. Now that "normal to guide" is an option in loft, you can probably get rid of these surfaces and simplify your model
    - Your curves have a lot of issues. Through point curves - if not used very carefully - generate complex and terrible surfaces. I would use the Bézier tool instead. These guidelines are for Alias, but they also apply to Onshape. https://help.autodesk.com/view/ALIAS/2024/ENU/?guid=GUID-A23E9E8C-6D6B-41AD-A0AB-3E98183FBC2E

    @S1mon your feedback is so helpful to me, especially because I am new to CAD stuff in general, I plan on using it in future projects, wish me luck! For the mean while I ended up just using @rafael_telgmann 's solution to just get it over with. I will make something new however using your feedback. Thanks to the both of you!
