Can I change the Default Material?

I use SW to design robot end of arm tools, so the finalweight of the tool is very important to me. Currently, the defaultmaterial density when no material is assigned looks to be that ofplastic. Is there a way to override this value?

Can I force new parts I create to be a specific material bydefault?

Are there any macros that I can run that will highlight any partsin my assembly that don't have a material assigned to them?

Thanks,
