You can position two fins in varying directions, such as on opposite sides of a corner.
			 If there are more than two fins, specify a direction for the first fin. The software equally spaces the remaining fins from the direction of the first fin.
To align the fins along the adjoining sides of a corner:
		 
- Select a face or edge adjoining the corner for the first fin. 
 The face is listed in Select a direction vector. 
- Set Number of Fins to 2.
- Clear Equally Spaced. Another option for Select a direction vector appears. 
- Select a face or edge on the opposite side of the corner to position the second fin.
