I took it into Draft, exploded it and erased all the stuff. Here it is! As soon as I exploded it the assembly broke into objects.

This file does have some issues, which might or might not make it unusable for your intended purposes, according to the check geometry tool. These same defects were included in your original file. Manufacturers sometimes include intentional defects in step models.

I also get the same result. (Face1 Face2 ....) Which I want is "Solid".

It means I need to merge these Faces to a Solid ?

I downgraded to faces in Lattice2 workbench, deleted the ones I didn't need, and created one that was missing using the tool in Part workbench (shape builder in the menu) to create the missing face using face from edges, then created shell from faces, and then finally solid from shell.

Yes, it is. I also generated SOLID like this.

I just want to know is there any way to do it quickly ?

Dont forget "step compound merge" - disabling that will not fuse different STEP solids so Exploding it later (which can take quite some time) will not be necessary.

It depends on the file. In some cases you might get different compounds, in which case you already have the part separated from the others. Sometimes you can quickly defeature. Sometimes the only way to get a file that will actually work for your purposes is to remodel. As I mentioned earlier, this model has defects and might or might not be suitable for your intended purposes.

I dont understand... What you want to "get"?
If that setting is unchecked the STEP file is imported AS IS. If it is checked all shells under a single COMPOUND in the STEP are merged into a single object when importing the file. So if you want to be able to separate individual shells after the import better not merge them in the first place.
