It seems there are two ways that Creo can calculate mass properties of hose and tube assemblies. One is using WT_LEN and the other is by assigning a material (.mtl) in the line stock file. The config option piping_material_source can be set to weight_length or material_dir to control which way it works. Which method are folks using for mobile hydraulics? It seems like wt_len works well for hoses but the material method might work better for tubes. We are having a bit of trouble with mass properties of some piping assys changing on us after multiple regenerations or re-opening the assy. In either case it seems like a material should not be assigned to the pipe part in the piping assy. Is that correct? Does anyone have a list pros/cons for which way to set up piping_material_source or other tips for using Creo to do mobile hydraulics?
We are on Creo 2.0 at the moment.
