GHPick

Pick Grasshopper components directly from their preview geometry in the Rhino viewport.

About GHPick

GHPick provides reverse selection between the Rhino viewport and Grasshopper.

In large Grasshopper definitions, finding which component is responsible for a particular piece of preview geometry can mean searching across a large canvas. GHPick reverses that workflow: start from the geometry you see in Rhino and go directly to the Grasshopper component behind it.

Simply Alt+Click on Windows or Option+Click on macOS on visible Grasshopper preview geometry. Alternatively, run the GHPick command and click the geometry you want to locate.

When several components overlap, GHPick displays a candidate list with the actual Grasshopper component icons. Hover over the candidates to highlight their corresponding geometry in the Rhino viewport, then click to locate the selected component on the Grasshopper canvas.

Historical Time for Blender
Architectural models are usually very good at representing space and rather bad at representing time. We can model a wall, a roof or an entire building in detail, but it is much harder to ask a simple historical question: what existed here in 1700? Historical Time is a small experimental add-on I developed for Blender. […]

Multiple Split Curves or Shatter All
This is my take to the problem of splitting multiple curves in their intersections. There may be other approaches, and there are even components inside plugins that do this, but I wanted to have my own in-house solution so I could understand what is going on. The image on the left shows the original 7 […]
Plaster tri-arch
Recent developments in digital design and fabrication tools have led architects and researchers to renew the interest in stereotomy. This interest converges with a growing ecological and economical conscience that matches classic stereotomy raw material needs: compression resistance materials. However, material resources or prefabrication time are still major counterparts for the adoption of this construction […]
“If then else” in GH
A common question I get is: how to replicate a “if then else” statement in Grasshopper. Here is my take. Explanation: if “First Number” is larger than “Second Number”, then output A, else output B. Or: if (FirstNumber>SecondNumber) {A} else {B}
Grasshopper – Pick region
Grasshopper does not seem to have the “pick region” feature from the Rhino Hatch command. I have created such an algorithm, taking advantage of recursive computing provided by the Hoopsnake plugin. You can download the .gh file here: FindRegion.gh The overall idea of the algorithm is to find the curve that has the shortest angle relative […]
Yet another values remapping
Another take on the problem of shaping a list of numbers according to a graph visual definition. The reason for not applying a Graph Mapper component directly deals with the way Graph Mapper has its settings adjusted. These are accessible through a double-click on the component, disallowing any kind of parametric adjustments (as with the […]

Contrary to most people I meet, I am a Magic Mouse fan. I never had any wrist pain, and I love the 2D touch scroll.
