7 A hollowcore element need not be uniform, but may instead contain additional recesses (three-dimensional cavities in the element) and core fillings. As a rule, recesses lower capacity, while core fillings increase it, relative to a pristine hollow-core. Both types are displayed on the element image, core fillings as dark grey rectangles, recesses as white rectangles.

11 The recesses are defined in a straightforward fashion: the three coordinates X, Y, and Z denote a single point of origin, and the width, height and length values then measure how far the we extrude the recess in each direction. During calculations, a recess is treated as having a block shape.

14 While defining a core filling, the only relevant values are the ID (which represents the core to be filled, from left, and ranges from 1 to the number of cores in the element), thestart X value, and the end X value. Essentially, the core filling is a cast through part of a given core, and the two x values represent the beginning and end of that cast. The cast will be given the same material properties as the hollowcore.

17 The dialog also provides a graphical helper. By clicking and dragging on the representation of the beam, you can move the ruler to a given point along the beam's X axis, at which point the side image will correctly display a section of the beam.

20 Lastly, the line crossing the graphical representation of a recess denotes a through-hole. One line means the hole does not go through the element, while two crossing lines means the recess is a hole through the element.
