Bill, While you are creating the analysis feature (area_analysis, for example), be sure to create a feature parameter (surface_area, for example) within the analysis feature. On your drawing, add a note with the text "&surface_area:fid_area_analysis:X" where X is the session id of the model that contains the analysis feature. I believe "fid" stands for "feature id", or at least that's how I remember it. Hope this helps, Tyler WF2
OK, I must be a moron, how do I create an analysis feature in WF3? I click the 'Analysis' icon or I click Insert - Model Datum - Analysis and the analysis box comes up. So far so good, just like WF2.
Now, I can name it (which never seems to take, so I skip it) and then I select the type. I can choose UDA, Relation, Excel Analysis or Mechanica. Odd, in WF2 I have a Measure and Model Analysis too, which is what I usually use. So, I'm not using Excel or Mechanica, so that leaves UDA or Relation. UDA gives me an error "There are no UDA local groups in current model." and won't let me do anything else, and Relation takes me straight to the relations editor, which isn't real helpful.
