I was working on a model, fixing the geometry and removing details to prepare the model for analyses. However, I saved my project and saved my work (I was using SpaceClaim), and shut down the software. When I re-opened the entire model was set to lightweight, and so I could not make any changes, nor use the geometry for my analyses. 

I have tried to load the components, I as well tried to set the source of my components as internal. This is has not worked. 

I attach the model that I would like to change from lightweight to normal model, so I can use it in my analysis. 

Thank you for your help,
