material properties

Hi, I'm a newbie to OnShape and the products we design typically include materials such as paper, paperboard, corrugated cardboard, and plastic sheets and films. The materials library in OnShape seems very limited on these types of materials, (for instance, no material seems to include the word paper, and plastics seem to…

Hi, To use the simulation functionality it is of course important to have the correct material properties. We can see that it is possible to add this manually now (previously it was only category, name and density that were supported) but is there any pre-defined material library that can be used or must all this…

Do the material libraries allow for more than density? Even when I add columns to the csv file such as tensile and yield strength, they do not show up in the material library when I import to OnShape. All I can ever view is the density. 

1 I import step files 2 I assign material to parts 3 Mass property says : one or more parts do not have material defined !! For my project it is kind important to define mass to parts and assemblies. did anyone had this issue? Any advice,
