Hello,
I'm having a problem with the Student Edition of Pro Engineer Wildfire 4.0 and Mechanism analysis with the dynamic analysis option on. If I have an arbitrarily simple subassembly (containing one part that is just a simple cube) within a top level assembly containing only that subassembly, I get the error message:
"The mass of one or more bodies in your mechanism is zero. Dynamic analyses require nonzero mass for all bodies. Please review mass properties using Info, Mechanism, Details."
The problem doesn't occur if the top level assembly contains only the nested part and no subassembly. The problem doesn't occur if only the subassembly is being analyzed with no top level assembly. Nested subassemblies seem to be the problem. Can anyone help me with this? You can download a small zip file containing the part and assembly files here:

</A>Any help would be appreciated. Thanks.
