## Latest Lessons (Tutorials)

In this advanced lesson, we are going to convert the relaxed mesh into a NURBS surface and learn how to penalize it using Weaverbird, Kangaroo, and Lunchbox.

In this Paracourse Lesson, we are going to model a Parametric Roof from scratch. First, we are going to model a simple rectangular plane for the base of the roof and then we are going to use a parametric curve to control the overall shape of the model.

In this Paracourse Lesson (25 Minutes), You can learn how to model a parametric vase by using a Perlin Noise Graph mapper. First, we are going to explain how to model the base surface of the vase by using Graph Mappers, and then we will use the Flow command to move a patterned curve to the Vase.

In this Paracourse Lesson, we are going to model a parametric freeform surface by defining two sections and a polar based rail. Then we are going to model a series of trusses and convert the surface into triangular panels.

In this ParaCourse lesson, we are going to model a twisting box with a completely parametric axis and then learn how to use Shift Paths, Explode Tree, and Flip matrix to model a series of tween surfaces from the box.

In this Paracourse lesson, we are going to model a parametric chair which is defined by a backbone curve and a series of wooden parts sitting on it. First, we are going to model the wooden part and then find the difference between the backbone and the sections.

## Latest Premium Definitions

In this Grasshopper Premium Definition, you can model a parametric Nurbs Stair. You can control the riser, width and number of steps.

In this Premium grasshopper definition you can model a parametric modular tower by dividing a base circle to create the base and then use the "random reduce" component to randomly delete the units of the tower.

In this grasshopper definition you can model the growth of a bionic form by generating random particles on a rectangular grid.

In this premium python definition you can create a desk organizer using metaballs.

In this premium python grasshopper definition you can simulate a basic agent behavior through defining an agent class in python component. Then you can define actions by writing functions inside the agent class.
