Filling/Combining a cavity to a Solid Body

I've been looking around to see if anyone else has had this issue but had no luck. I wanted to know if there was a way to combine a SolidBody to a filled cavity. What I've essential tried so far are two different methods.


The first one being a surface fill method. I took contours of the cavities, surface filled the cavities, and thickened them. The problem I found with this method is that the thickened surfaces do not merge with the solid model and are essentially left as their own solid bodies. I have tried to use the "combine" feature to merge the thickened surfaces with the part model but have had no luck and I'm basically left with this message.

Thickened surfaces do no combine


The second method I tried was by creating the fillings in a part file, mate the fillings in an assembly file to fill in the cavities, and then save the assembly file in to a part file. With the part file made, it still recognizes the file as 6 different bodies. I essentially tried to force combine the solid parts by trying to boss extrude a rectangular sketch, as shown, that intersect the two solid bodies hoping to form one solid part. As a result, I've had no luck with this.

Forced Merge


I haven't really had luck with the intersect feature as it does not recognize the cavities separately when filled with a rectangular box to try and distinguish the cavities from the part.


Ultimately, I just want the fill the cavities and form one body. Either that or recreate the part as a solid entirely, which I have also tried doing with 3d sketches and sweep features but have had trouble doing due to the complex curves that exist with the part itself.


Any help will be greatly appreciated.
