The special characteristic of fillings is the fact that the distance between the assigned posts is not known at definition.

To avoid having to define an own cell for each possible distance, the elements are adapted to the current dimension by means of the options Stretch/Upset and Move. In addition, filling elements which once were defined can be regularly multiplied by means of dynamic distribution.

A twisted filler rod has e. g. to be modeled only once to arrange it in a grid of 100-110 mm in the handrail segments.

The filling has to be defined in the WCS as well. The positive z-axis corresponds to the height of the handrail. At insertion, the positive x-axis is always aligned towards the running direction of the corresponding poly-line segment. The origin (0, 0, 0) of the WCS lies in the middle of the cell.

Define two cell tags DP1 and DP2 to be able to place the fillings correctly. The filling is created later in a way that its cell tags and those of the posts are laying exactly one above the other.

If you want a dynamic distribution, all elements to be distributed get the code FB in the parts properties under ‘Note 2’. Two other cell tags FBSTART and FBEND determine the nominal grid size including the gaps.

Depending on the default settings for length adaptation, the actual grid size can however be bigger or smaller. You can limit the area in order to determine borders – for example the protection against falling through the bars. If you enter the value MIN=100 in the input field for the cell attribute FBSTART and the value MAX=110 in the input field for the cell attribute FBEND, the distance will always be between 100 and 110 mm.
