This grasshopper definition uses a length and width input along with an attractor point to create a varied and complex attraction script. Many variables may be controlled via sliders including: the tube shape (fillet size based on proximity to attractor), impact of attractor on tube length, the end condition of the tubes (flat stepped or rotated), the number of tubes in u v direction, as well as many other preview options and final components to bake to rhino.

This grasshopper definition uses a spline to create a roller coaster. Parameters include the number of cross braces holding the rails and the width, depth and size of the rails. The definition automatically creates vertical supports and performs an intersection test so vertical members do not interfere with the track when it cross over itself.
this folded wall can be created from any spline in plan... its elevation (heights of the layers) are drawn and input into the grasshopper definition. Several variables can be controlled including, with of either half, the randomness of the folds, how many folds and some corrections for length differences when walls are curving.
