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…

Simple Unit Conversion Script
Hey all -
While working on a project I came upon the need to do some unit conversion within GH, so I decided to write a script to handle this. I've attached it as a user object. It takes two strings, defining the input and output unit systems, in the form of "mm" or "in^2" or "yd^3" etc. It will then output the necessary conversion factor. It also optionally accepts a list of values, and will convert them for you if they are present.
A word of caution: I…

automated crosshatching definition
There was a request for the basic definition I used to make this image.
Process:
Choose an image, and live trace it in illustrator. Expand the live trace, and save the illustrator file. Export the live trace as a jpg or other bitmap format.
In Rhino, import the image with the PictureFrame command. Then import the illustrator file and scale the curves to the…

GH-Only Catmull-Clark Subdivision
As an exercise, I decided to try to implement the Catmull-Clark subdivision algorithm in Grasshopper alone. This means no scripts, and no 3rd-party components (such as weaverbird). This is not designed to be a utility - by all means, if you have to subdivide a mesh in this way, just use Weaverbird. I am always interested in the way… Continue

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.
