#### 2.1.6.1. 1-D Look-up Table

A 1-D Look-up Table can be used to create a distribution of a scalars or vectors in one direction. Such a distribution can be used in:

- the definition of an Oriented Selection Set Reference Direction.

- the definition of the draping angle.

- the definition of the ply thickness.

A 1-D Look-Up table is defined by an origin, a direction vector, and a column of at least one quantity varying along the direction vector. The values of the defined quantity are inter- or extrapolated to the element centers in the mesh. The 1-D Look-Up table uses a scalar product to project the vector between origin and element center on to the Look-Up Table direction vector and look-up the desired value at that point.
