Help to convert my file

Hello fellows,
I need to convert my .stl file into a solidworks file and into a parasolid .x_t , but i don't have this software.Attached is the .stl file.I hope you could help me.

Thanks in advance,
Megs

There is no automatic way to convert .stl files into solid models.
I've been working at a reverse engineering company where they converted scan data (.stl files) into solid formats.
You need a special kind of software for that, (I think we used GeoMagic or something like that), and it's still a time consuming job.

For a simple model, easiest way is to redraw it in Solidworks, but a model like this, that's not an option. Your only option is to find someone who specializes in turning .stl files in solid models, but for a model like this, that will be quite expensive.

Thank you Sir Ron.

I have a nurbs surfaced model but some areas need filled in with a surface.

Then you have some real conversion options.

I will pm you with details if you want this

Do you just want the model made solid so you can make it hollow to save on price?
I can make it hollow with a 1.25mm wall thickness
This has a 30.24cm3 volume, compared with your original model at 154.74cm3.
You can have the model if you want it.

Thank you Sir Jacant and Sir CadNinja. I really appreciate your help.Thanks a lot.

More Power,
Megs
