Can't seem to get User Defined Analysis to work right.

Hello all.I am currently learning to use Creo and I have a task that requires generating cross section data over the length of a varying cross section model. I need cross section data at 1" increments across the total length of 159". That is a lot of cross sections to analyze

If I understand your goal properly, you'll need to try the following:

Make sure the field point is placed on a feature that the point can "travel" on from one end of your part to the other. This should be a datum curve that starts at one end of the part and exists along a path that would have the point move through the the region you'd like to measure. Then make sure you create just one datum plane that uses the field point as a reference the plane must pass through. Create the area measure using the plane that is constained by the field point. Group these three items and then make the UDA. The UDA will force the datum point to move from one end of the datum curve to the other and bring the datum plane with it, thereby generating a new cross-sectional area for every increment. Have the UDA provde 159 measurements using the "Settings" button in the UDA dialog box. You can have it generate a graph from this analysis that you can export as an Excel file. I hope this makes sense.

Good Luck

Makes perfect sense Chris.

I did as you suggested (almost) and I am now getting the variable results I expected and furthermore I was pleasantly surprised when the solver automatically popped up excel with the data all lined up and a graph.

The frosting on the cake, however usefull or not, was the graphical display that shows up actually on the model.

At the least it is a fantastic first visual that allows for that initial sanity check of "is thing doing what I think it should".

Thanks for your help. This saved about 3 days worth of copy paste single plane analysis.
