Last night I was working on a polygon shapefile, I was using the freehand tool to draw them. Whenever I would finish a polygon It would save as several (but not too many at all) straight lines. I never saved the MXD file. Today I created a new one, with the same shapefiles, but whenever I create a polygon with the freehand tool, it does it as bezier curves wich later turn to straight lines (this time a whole lot of them). How can I go back?
