I created a surface from two fully defined splines.

The surface was created with the fill surface and, for the boundaries, I used extruded surface from the splines, because I wanted the “tangent to face” and “curvature to face” functions to work.

After that I created a solid body thickening the surface, then I mirrored the body.

I was not able to create a single solid body using the combine command. SolidWorks give me some error.

Please see attached file MirrorProblem.

Please notice that I was able to obtain what I wanted changing the order of the functions: I used the mirror command before the thickening command. Please see the file MirrorWorks. This is the reslut I get:

Now the problem is that I have some more complex model that I am working with that may have some thickened surfaces (or solid bodies) that I need to combine with some surfaces. What I am doing now is that I transform the solid bodies to a surface but this is not always simple…

Could you give me any suggestion? Is it possible to make the combine tool work with “complex” solid bodies?

Thanks!
