Fillet Command tips - AutoCAD

Question

I’m in the middle of a long run of Fillets, how do I keep the command going and also is there a way to quickly go back to a zero radius to use the fillet as a trim/extend tool on untidy corners?

Answer

Start the Fillet command as usual, and then select the modifier named Multiple, either by entering M on the keyboard or via the right-click mouse menu. Continue as usual, selecting the Radius modifier as required  as you work. To temporarily override the current radii value and apply a zeroradius fillet, simply hold down the Shift key and click on the objects to be filleted. Releasing the shift key returns the fillet back to the previous radii value
