Facades+ Workshop July 25

It’s been a long time since I posted here, but wanted to come back on to promote my upcoming Grasshopper workshop at the Facades+ Conference in Chicago on July 25!  http://www.facadesplus.com/collaborative-design-and-analysis/ It will be a really exciting opportunity to push the boundaries of Grasshopper as a collaborative tool – we’ll be exploring strategies to build multi-user grasshopper […]

2012 in review

Since I haven’t been posting much lately I thought it would be fun to give a little recap of this last year of my life in terms of art, architecture, design, and technology. January to May – Thesis For the spring semester, I was hard at work on my thesis project at Cornell. Entitled “Case […]

Tweet2Form: The Formalist Tweetbot!

I just finished putting together a beta version of a little project. It’s a tweetbot powered by a grasshopper definition. The bot transforms a cube according to a series of operations you specify, and then tweets a picture of the resulting form. There are currently 11 formal operations that the bot understands: split bridge stretch […]

Auto-Document GH Libraries

I wrote a little script for myself that I thought might be useful to other GH developers or teachers. Feed it a component from any library (such as a plug-in you're developing), and it will list and describe all the components in that library. It can also generate a markdown-formatted text file,…

Create Snippets with Grasshopper

Grasshopper by default allows you to save individual components and clusters as "user objects," which can be re-used over and over again. However, sometimes you want to save a group of components without clustering them - like a component with pre-defined value lists or sliders attached, or special configurations with plugins like kangaroo, honeybee, or anemone.

The attached script lets you do just that - create a user object that can automatically place multiple components at…

Wire Display Toggle Switch

There is an ongoing debate in my office between those who like to organize their definitions with hidden wires for the sake of cleanliness, and those who hate them because it makes definitions hard to debug. In order to sidestep any drama, I made a little script that lets you switch all the wires in a document between "Hidden" and "Faint." It will leave all wires set to default alone. 

Download it here: …

Hi Andrew,

I am trying to use "Render Text to Screen" to visualize texts in the Rhino viewports other than "Perspective, Top and Back", but it doesn't work. (it only works in "Perspective, Top and Back" viewports on my laptop.)

Could you please let me know what could be the problems? Thank you very much in advance!

Hi Andrew,
I see you are quite fluent in RhinoCommon.
Was RhinoCommon SDK your only source for learning it?
Thank you.

hi Andrew, I actually have a big problem trying to import rhino text objects to grasshopper to create a points cloud; fortunatly I found the solution in one of  your old posts...http://www.grasshopper3d.com/forum/topics/using-number-text-objects-for?commentId=2985220%3AComment%3A168316

but it doesn't work for me... certainly because of the new version of GH (0.9)... I'm using Rhino 4. I really need your help on it, I didn't find other solution anywhere else and don't know anything in scripts...  Thank you so much !

hi Andrew,

i need help editting the qvoronoi defination by demitrie. When ever i give my points rather than the random points, the qvoronoi turns red and the defination fails to work. Also that i need to give the bounding box to be my site. how is that possible? Its my thesis year and im running out of time. I am new to grasshopper and seek guidance. Thankyou.
