A solution we have used for generating impeller blades by points using an Excel spreadsheet, is to create associative points. Associative points have X, Y, & Z values that are driven by expressions. These expressions are then populated into the MODELING spreadsheet in UG. From there a new link can be created to point to the Excel spreadsheet, but this link can only be made on a Windows platform (such as NT), since Unix does not support Excel, at least through V18. I don't know about NX, because we haven't implemented yet. The Unix spreadsheet (Xess) does not work well with others, so if you have no NT workstations, you are stuck with the UG/Open API method. One last hint is don't try to link to Excel through Hummingbird or the like, because those are simply Unix emulators. However, a terminal server set-up on a Unix Wrokstation, such as Citrix, that emulates an NT UG set-up should work.
