Hello. I am still drawn between SolidWorks and Inventor. So far, I am more comfortable with the user interface of solidworks. However, I have some CAD files (developed by others in Inventor) that I don't seem to be able to import to SW successfully 100%. Also, it seems that there are more books related to Inventor. Recently, I came across a book titled "Autodesk Inventor Simulation 2011". It teaches a lot about doing simulations in Inventor. You can have a look at it from Amazon's website. Is there something like that for SolidWorks? Thanks.
