How can I convert this 3D dwg file into solid/stl/any other type that can be opened by Solidworks?

I have tried so many times to use the convtosolid function but it does not work because it said it is self intersects or not close. How can I fix this and convert it? Thank you so much!

Which program was used to create that file? Where is it coming from? 

Can you post the dwg file (or at least a part of it) please?

@Anonymous ,

A simple file EXPORT will allow you to export to *.STL file.

Here is the file. I appreciate it. I can't simply use the convert file type to convert it into a solid file.

In principle, the task can be solved, but not "with one keystroke".
The model consists of 1572 meshes and several 3DFaces.
First the meshes.
Each of the meshes represents a single component (part).
Follow these steps (>>Video_1<< )

- explode a mesh with the command explode -> several 3DFaces are created
- convert the 3DFaces to Surfaces (convtosurface)
- create a solid from the surfaces with the command Sculpt.

Repeat this for each of the 1572 meshes ...

But:

It is possible to edit multiple meshes at the same time (>>Video_2<< ). But then ONE single solid is created for several parts. If this is acceptable (I dont't know what you further want to do with this model in SW), ok. If not acceptable, you can separate the solid into individual solids, as long as they do not overlap or touch.
>>Video_3<<  shows a situation where two components touch each other. If both meshes are processed at the same time, the result is ONE solid. This can NOT be separated into two parts. If you need two parts (because you maybe want to simulate the rotation between the parts) you have to process each of the meshes separately.

>>Video_4<<  shows a situation in which no solid can be created from the surfaces, because the surfaces do not circumscribe a watertight volume. If you are lucky, you can "fix" this part with little effort and then successfully create a solid.

>>Video_5<< shows a situation where creating a solid also fails. On such parts, a successful repair can be very hard to do, since the problem-causing spot/s is/are not easy to find and to repair. 

Another problem would be the 3DFaces contained in the original file. Converting them into meaningful solids will require a huge effort, since they are not structured in a meaningful way as individual components.

All in all: It might be possible to convert the model to solids, but with a very high effort. Since I don't know what the model will be used for later and how it might be further processed, you have to decide for yourself whether the expected result is worth the effort.
