Instead of using Ctrl+C/Ctrl+V please use the copy and paste buttons within the AttributeCreator towards the bottom right, this should copy the values across all rows/columns:
Please note this option will only work across transformers of the same type, e.g. you cannot Copy from an AttributeCreator to an AttributeManager.
Hello @jamal , thanks for your workspaces! After taking a look, I think you need to upgrade your AttributeCreator transformer in the 'CADParcels_LinesCirclesTexts_To_GIS' workspace. Transformers whose version is earlier than the latest version available appear in the Navigator, under Upgradeable Transformers. New to working with transformer versions? Let me know if you were able to upgrade!
