Detail - Align

Align Polygons (Detail > Polygons > Align) attempts to automatically make all polygons face the correct direction. After using, you may still need to use the Flip Polygons command (Detail > Polygons > Flip) before you are done.

To align polygons:

1. Select an area that includes the polygons needing to be flipped, as well as a large number of polygons facing the correct direction. Selecting polygons that share points and edges helps.
   
   

1. Choose Detail > Polygons > Align . Verify that the polygons were flipped as desired.
