PointLinker for Inventor
Inventor can import point data from an Excel file, but once the data has been imported, the link with the Excel file is not retained. If the user then updates the point data in the Excel file, the data must be manually re-imported and the associated model re-constructed. This is a time consuming and isnefficient exercise. The Point Linker for Inventor tool allows Inventor users to import points from an Excel file, and retain a link to that file. Users can import data (as with the existing command), update with new data, or resolve to another Excel file.
