I am trying to use Model Builder with Extract with Mask. The masks (polygons) are in a file database and the raster is a standalone GRID. When I run the model it exits with an error that is the Table name is invalid. I tried to investigate the meaning and I came across two explanations. One: don't start names with digits. Two: names can't be longer than 13 characters. I think I've met those restrictions, but I still get the error. I think I also read somewhere that you should save to a database, but I swear I've done something similar to this months back and saved in a folder without problem. I'm out of ideas at this point.
