Flay is a force-layer reactor for Autodesk® AutoCAD®, which automatically places predefined objects (drawing commands or specified blocks) to predefined layers.

Using a text file (.TAB) with the list of commands and layers, you can force AutoCAD to e.g. place all texts to the layer "ANNOTATIONS", place all hatches to the layer "HATCHING" and dimensions to the "DIMS" layers with predefined layer colors. You can also set block names which should be inserted to predefined layers - e.g. all Chair* and Table* blocks to the Furniture layer.

You can customize the FLAY.TAB file (or make your own file) and save the file in any folder location.
