Hi Folks I have a problem here with mass properties on edited SW materials. I have a part template with material density set to 0.0078g/mm³ (stainless steel). In some of these parts I added the SW material to get the real view graphic display. I then regret this and removed that material without checking what happened to the mass properties. If I now go back and have a look it's set to 0.001g/mm³ (water) and I can't change it. My changes in the document properties will not be accepted. Is there anybody who has an idea about what to do? I normally use DbWorks to set my materials and densities, but this one act just the same with DbW unactivate. SW Office 2005 Sp 0.1
