Explore intersect and transform tabs to understand their mathematical relationship in Grasshopper. Learn how these operations support parametric design workflows.

Explore brep intersections in parametric design, solving multiple brep intersections simultaneously and visualizing intersecting lines to reveal all intersections.

Explore working with regions in Rhino Grasshopper, learning to split items, trim them, and add regions together in 2D shapes via region intersect.

Explore the transform-array approach in Rhino Grasshopper, learning how to create and adjust arrays by transforming geometry, moving centers, and experimenting with different methods to keep geometry editable.

Learn how to render Grasshopper code using the render preview function to turn offset splints into realistic visuals, including animated renders in Grasshopper.

Construct nurbs curves by breaking a curve into control points, creating a constructed line, and offsetting points in the z direction with a slider to form preview rotated panels.

Loft the top and bottom curves into a surface, create a thin pipe, rotate the geometry around an axis with a domain and range in radians, and render a preview.

Learn to animate Grasshopper renders using render tools to create sun study, animation, path animation, or 360-degree sequences, adjust frames, and export or capture the result.

Divide a surface into U and V grids, capture UV input, and generate curves from grid vertices, adjusting point counts with a slider to shape a pavilion.

Add hex panels to a surface with U and V sliders, range from five to fifty, and array the panels along the surface using a useful plugin.

Explore advanced Rhino Grasshopper workflows using trees and sets to create complex connections for hex panels. Learn to project, scale, and loft geometry for architectural forms.

Create parametric cluster forms with a panel-based tree, centroids, and area command-based scaling. Align four panel sets into a planar polygon, flipping the matrix for grouped geometry.

Learn to create mushroom-inspired columns in Rhino Grasshopper by elevating points on a curve, using z-values to control center height, and building clustered hex-panel profiles.

Bake panels into layers for the x panel, stem, and furniture, exploring multiple versions. Project the base into a curve and bake it into the fern layer with curve piping.

Explore essential Grasshopper and Rhino plugins like Kangaroo Physics and Ladybug to enhance analysis, form development, and environmental design, including climate data and lighting, with installation basics.

Explore the Galapagos evolutionary solver's area finder to optimize equal-area divisions on an unusual footprint, using gene pools, sliders, and surface splits to measure areas.

Explore using the galapagos solver to minimize area difference by adjusting genomes across sliders, selecting top genomes, and iterating with different gene pools to approach equal areas.

Manually adapt a Galapagos solution to minimize intersections and find the shortest path by guiding the evolutionary solver with targeted inputs and saving a gene.

Explore creating a sun path diagram in Grasshopper, plug in center points and locations, set analysis periods by month and hour, and visualize sun position and temperature data with Ladybug.
