The following example shows the possibilities of handrail construction with user-defined cells and dynamic distribution of filler rods.

The different posts and the filling element are constructed in the cell templates and the filling element only contains the principle. At generation along the poly-line it will be adapted to the current segment length. As it is only a matter of corners of 90° and 45°, the whole construction can be saved in a template and be reproduced.

The neighboring figure shows the cell of the filling element in detail.

Since both filler rods alternate, they are modeled together, too. An exact distribution in a 150 mm grid including length compensation at the beginning and at the end of the segment is desired.  This is why you find two cells FBSTART and FBEND each on the right and left side of the bars (with the input demand MIN and MAX=150). The filler rods and spheres have the code FB and in the drill holes of the upper butt straps you will find the cell tags DP1 and DP2 for the adaptation to the posts.

The posts also have such butt straps with the same tags in the drill holes of the butt straps for fixation.

In handrail function, it is specified that the filling element as well as the supports have to form their own groups. An assembly can be built out of two supports and a filling element in order to display the main dimensions of construction and installation as common drawing.

The following drawing is an automatic 2D-production drawing of a filling segment. Here you see that the length compensation of the distribution was effected at the edges and that the desired grid is exactly kept.

The possible 2D-detailing of a whole assembly shows how the filling element is placed between the different posts.

Due to a free construction via user-defined cells (which adapt themselves dynamically) and due to the forming of parent and subordinate groups, you get complex handrails including 2D-plans in no time at all.

Finally, here an the overall view as horizontal projection with the most important dimensions of the complete handrail.
