Say I load a model into the PreForm software, discover there may be in issue with building it (supports, pockets, etc). I go back into my design software, fix the issue. I then have to reload the model back into the PreForm software and set it back up? You could add an option to just “Reload” the file, (keeping position, orientation, scale, duplicates, etc) and the updated geometry would now be included and rechecked by the PreForm software.
