"Try this - the approach is to use "Cull Duplicate Points" on all the vertices of all polylines, and then match the original polyline vertices back to the reduced set.  "

"Hi Martin - This appears to be a bug with the new RhinoCommon shipping with Rhino 6 WIP. I am following up with the rhino developers here: https://discourse.mcneel.com/t/sdk-change-linetype-table-access/36029/7 In the meantime the attached…"

"It's not exactly what you're asking for, but MetaHopper lets you control the size and text of a Scribble - so you have "inputs" on it and update it dynamically. It also lets you bypass the 100pt font size limit so you can make…"

Andrew Heumann replied to Josef Stagg, PhD's discussion Reporting Parameters

Andrew Heumann replied to Xavier AM's discussion IO Generated Errors - which component?

"I should also mention that the Data Dam has an in-built "timer" of its own, that allows you to "throttle" your data as I think you're attempting to do."

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.
