Attributor enables drop-down lists and control of mandatory values on Autodesk® AutoCAD® block attribute tags. Using simple text files, you can configure drop-down lists (aka look up lists) on specific block attributes and flag certain tags as mandatory/required entries. Users can then quickly and easily choose the desired value from a context specific list. This ensures accurate data entry and speeds up data capture.
