I lost my hard drive and could only recover the assembly file and cannot open the assembly due to the fact that all the other parts is "missing". I can open this assembly file in E-drawings showing all the detail of the model. So it seems to me that the assembly file has more detail in it as just a jpg picture of the assembly. All that I need is a parasolid file or any other format of this assembly file so that I can import it again in solidworks and perform a simulation study on it. I don't need any "intelligence" anymore on the geometry. Is there any way that I can get such a file from the assembly file.
