Dear all, I’m still a beginner 😊 is it possible to undo a chamfer/filet corner of an object. After I changed the app or haven’t touched my iPad for a while I can’t undo the action anymore

many many thanks in advance !!!

Once you close the design, the reverse changes are no longer possible.

You can highlight the fillet and press delete, or set the value to zero.  
Sometimes the replace face tool can be an option
