Andrew Heumann replied to Harsh Gupta's discussion Using Grasshopper from C# via API
"you can certainly build GH files programmatically - but it depends what you mean by "external" c# application. You will not be able to access much of use from the GH SDK outside of a running instance of GH (meaning you could write a plugin…"

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 process.The webinar is at…See More

Kyle Vansice commented on Andrew Heumann's group Doodlebug
"Hey Andrew, thanks for the plugin! One quick question: can you link views other than "Top?" Say Perspective, Front, Right?  Grasshopper 1.0 has a Make2D component which would make perspective drawings much easier with doodlebug."

Andrew Heumann replied to Andrei Nejur's discussion Help using a custom type as input for the script component.
"it's possible (haven't tested this myself) that you can avoid setting the app-level COFF toggle by modifying the load setting for your plug-in alone - this can be done on a per-user basis in the GH preferences (solver / plug-in loading,…"

Andrew Heumann replied to Andrei Nejur's discussion Help using a custom type as input for the script component.
"Hey Andrei :)  The only way I know of to be able to script with custom data types is to launch grasshopper with "COFF Loading" disabled. (this option is accessible from the GrasshopperDeveloperSettings command.) If you do this, you…"

Andrew Heumann replied to Eirik K's discussion Passing a proprietary class from one GH_Component to antother
"The "Goo" and custom param wrapping method is absolutely the "correct" way to do this. However, it is not strictly necessary - if you use "AddGenericParam" for your inputs and outputs expecting custom types, you can…"

Andrew Heumann replied to w2's discussion Accessing to GH_Panel content in C# component
"Anything not fed in via an input will live in UserText - but as soon as you're plugging something into it, the panel behaves like any old Param, meaning you need to get access to its VolatileData property. Easy enough if all you want is the raw…"

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 !
