"Human also supports the re-definition of blocks - and you can specify attributes (layer and other information) just like you would if baking. "

Andrew Heumann replied to Miracle Ma's discussion Seems that galapagos don't wait for anemone's finishing.
"try anemone's "fast loop" - it interacts with the solver differently than the regular anemone loop components - I can't guarantee it will play well with galapagos but I'd wager you've got a better chance. "

Andrew Heumann replied to Daniel's discussion Button within Grasshopper to switch between Grasshopper Defintions
"this doesn't exist in any plugin that I know of, but it can be scripted. You can simply assign a new document (that's currently open) to the Grasshopper.Instances.ActiveCanvas.Document property and it will switch to that document.…"

Andrew Heumann replied to Daniel's discussion Will Grasshopper 2.0 be much faster?
"is this necessarily desirable? I understand in most cases it would be - but in the case of Human UI I actually rely on the fact that I'm *not* passing a deep copy of an object from component to component and instead addressing the same object…"

Andrew Heumann replied to Nazanin Tabatabaei's discussion input a list

Andrew Heumann replied to Christian Gartland's discussion GH Python copy module?
"copy should be present in ironpython version 2.6 or later - I think gh ships with at least 2.7. it doesn't show up in the autocomplete menu for me but your code in the "would like to do" section executes just fine in gh python. "

GH Webinar - GH Plug-in Development in C#

Just a little blatant self promotion :)

If you have a basic knowledge of working with C# scripts in Grasshopper but want to take it to the next level and start building your own GHAs, you may be interested in the webinar I'm teaching tomorrow for performance.network. We will go through the basics of plug-in development - the structure of the code, how to get data in and out of a component, and the debugging…

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…

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 !

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.
