Question
Use of Material Files
WF4 & WF5
I'd like some feedback on how folks are using material files in Pro/E.
At this point, we do not use any material files in our models for a
variety of reasons. I'm curious how you have overcome these significant
issues:
1. There's no obvious indication that a material is assigned to a
model. The only way I've seen to tell (outside of the materials dialog)
is that a PTC_MATERIAL_NAME parameter is created and is restricted to
the value defined in the file.
2. While the material file will set mass properties values, there's
nothing to prevent a user from changing those values. So, if I assign
6061 aluminum to my part, a user can override the density to make it as
heavy as lead and there is no warning and that PTC_MATERIAL_NAME
parameter still says 6061 and the materials dialog still shows that 6061
is assigned. Again, since there's no indication that a material was
assigned to the part, so there's no way for the user to know ahead of
time.
I guess a secondary question would be what value to I get from using
them. I know that I need them for running analysis in Mechanica, but
beyond that I'm not sure what I'd gain. We are not a manufacturing
organization with defined materials in house that we want to use,
although we might get such restrictions from our clients.
This was brought up because a user completed Mechanica training and
wondered about our material library, which is only what we got from PTC.
