I'm experiencing the 2017 edition freezing when I try to perform an extruded cut on a flat plane on a drawing.......it happens repeatedly no matter how I generate the cut 'lines' (ie offset line, offset on a plane and drawn from 'centre rectangle')  I have also made a second drawing of similar layout and yet the cut executes as expected....... The preview function operates fine and shows just what I expect but then when I come to initiate the 'cut' it hangs........ 

No messages or warnings are shown and as I mention the function works elsewhere......
