We have an issue with Pro/E referencing the wrong CS with respect to it's location in an assembly.
Here is our current process:
1. In assembly, activate part requiring CG analysis
2. Select Analysis>Model>Mass Properties
3. In Analysis box, select CS we want to measure CG relative to (FED130_CS) & Compute.
Results:
CENTER OF GRAVITY with respect to FED130_CS coordinate frame:
X Y Z 2.0845767e-01 6.2798746e+00 1.7171229e-01 INCH
The XYX results above are not correct and are actually relative to the default CS of the part, even though it clearly states FED130_CS.
We cannot determine what we are doing wrong. Our workaround has been:
1. Activate part in assembly
2. Creat new CS at FED130_CS location
3. Open part
4. Calculate mass properties again, selecting the newly created CS.
Any advice is appreciated. We want to eleiminate this extra step of creating a new CS for every part as we have thousands of parts in our vehicle and be confident that when it gives us a CG relative to a stated CS in assembly mode, we can trust it.
Thanks in advance,
Terry
