possible to append component menu items to GH_Cluster?

I've been using a C# script that lives inside a cluster to control its displayed Message - it works quite well. I can gain access to the cluster object in the parent document and call methods on it.However, I can't figure out any way (from within a script inside the cluster) to add component menu items to that cluster. I've developed custom GHAs before and successfully overridden AppendAdditionalComponentMenuItems etc - is there any other mechanism to do this to a component menu at runtime? My…See More

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: …

Tweet2Form: GH-Powered 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 10 formal operations that the bot understands:

split

bridge

stretch

scale

shearA (Shear angular)…

Find and Replace in Grasshopper Documents

originally posted here

Since David Rutten added to GH the ability to set a default text panel background color, I’ve had my panels set to be white instead of the default bright yellow. But in all my old definitions, the panels remain yellow, and it drives me nuts. I was going through and changing them manually when it occurred to me that there was a much better way, based on a trick I saw David mention in a…

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 !

Hello Andrew;

Great work on the Origami simulation showed here: http://www.grasshopper3d.com/video/rigid-origami-with-kangaroo-1?commentId=2985220%3AComment%3A150253&xg_source=activity

 

just wondering if you can share the definition?

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.

Best.
