QUESTION: What is the Definition of Skew angle within the ABC wizard?

ANSWER:

In the ABC wizard user can input the Skew angle or the bearing

The term ‘angle of skew’ or ‘skew angle is basically the angle between a normal/perpendicular to the alignment/centerline of the bridge and the centerline of the pier . Thus, on a straight bridge, the skew angle at all supports would normally be the same and the term skew angle can be applied to the bridge as a whole.　

ABC  wizard supports the keyword NORMAL to denote a normal or radial orientation or the command SKEW XX where XX is a positive or negative skew (from a normal) angle. These two methods of specifying angles makes it very easy to specify normal or skewed supports. Please see the attached screen shot which explains the Basic skew angle as well as Positive and negative Skew..
