mesh enabler solid output from stl inventor

To save both you and me time, I have uploaded all files to my web host, so that you can view, attempt things. However, I do not have the budget to purchase any products to complete this task. I have a huge range of software installed on my pc which I can abuse, if you know a way using any of the following, I would appreciate knowing it. I need the file to be converted into a solid so that I can manipulate it within Autodesk software to use within my design. (Not completely sure I understand how to use this properly, happy to try this method again if you can give me a guide)

Attempted to convert shape, unsuccessfully.Attempted to import using multiple formats.Attempted to use Autodesk Mesh Enabler and convert the mesh after importing.Attempted to import using inbuilt systems without success.imported obj file & other file types to get error:.The closest I got was a wire mesh shape which claimed to be converted, however, it wasn't possible to interact with and modify. So I attempted to export this file to use it within Autodesk inventor, and I could not get anything to convert it into a solid shape. So I decided to move to a more modelling based program, Zbrush 4R7, which make a great model (head.obj in the files section).

So, I attempted to design the main features, the head in Autodesk originally, however, could not get it to look how I wanted it to. The idea behind the design is a Mountain troll leaning on some buildings with LED veins which change colour, lava falling from the mouth and down the sides of the buildings it's leaning on. Quick background about the projectįor uni, I have to create a stage design for a festival. If you do not want to view the images, files or additional information, please skip all other sections. This help request is explained in detail in parts 2,3 & 4. I can't figure this out and have tried looking at multiple google searches' and community posts which all seem to be out of date. I'm working on a project for a piece of coursework which I really need a hand with.
