I've just realized that my list of materials is no longer available. By this I mean if I open a part I've built, go to iproperties -> physical tab and I click on the "Materials" drop down menu the only options that show up are the material I've assigned to the part already, and the default. This wasn't the case before and it may have something to do with following partly these directions http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=8781931&linkID=9242018.
I'm using Inventor 2011 student version. Please help me get my materials list back. I'm fighting a project deadline and this is killing me. Thank you!
