o 'curves'. In the script, it still expects 'x'. I have to add another input before it will refresh and call the input 'curves'.
2/ Upon loading gh, it gives the following error message. This has only happened since upgrading from version 9.0075 to 9.0076
Priority: PreLoad
{
Method not found: 'System.String Grasshopper.Kernel.GH_ComponentServer.CopyFileToRoamingFolder(System.String, Boolean)'.
MissingMethodException
}
3/ I also posted a few bugs here a while ago, just wanted to bump that up:

the "port" input. I would really appreciate any help!
For example, my Arduino board is connected to COM 3. The "ports available" component correctly identifies this port, and I know there is nothing wrong with the port itself since the Arduino communicates through COM 3 without problem when using an Arduino sketch.
The runtime error produced by the Firefly open/close port component:
1. Solution exception:Could not load type 'Grasshopper.Instances' from assembly 'Grasshopper, Version=1.0.0.20, Culture=neutral, PulicKeyToken=null'.
System specs:
Windows 7 64-bit
Rhinoceros 4.0 SR 9
Grasshopper Build 0.8.006
Firefly Build 1.0067
Arduino Uno R3
These error messages appear when Grasshopper is loaded from Rhino. They first appeared when Firefly was installed:
Object: Mega_Write (level 1){ Exception has been thrown by the target of an invocation. TargetInvocationException}
Object: Mega_Write (level 2){ Method not found: 'Void Grasshopper.Kernel.GH_PersistentParam`1.SetPersistentData(System.Object[])'. MissingMethodException}
Object: Uno_Write (level 1){ Exception has been thrown by the target of an invocation. TargetInvocationException}
Object: Uno_Write (level 2){ Method not found: 'Void Grasshopper.Kernel.GH_PersistentParam`1.SetPersistentData(System.Object[])'. MissingMethodException}
Object: ArduinoBake (level 1){ Exception has been thrown by the target of an invocation. TargetInvocationException}
Object: ArduinoBake (level 2){ Method not found: 'Void Grasshopper.Kernel.GH_PersistentParam`1.SetPersistentData(System.Object[])'. MissingMethodException}
Thank you for your help!

that data via serial to an external program to play as MIDI.
The problem is, I am using a third-party (Spikenzie Labs) serial-to-midi converter that cannot speak to the COM port while Firefly also does. Bear with me, as I am just starting to figure this out, but I imagine the following possibilities:
1. Hardwire an actual MIDI-out into my prototype and code it so that the signal is sent this way. Get a MIDI-to-USB cable and go into a different COM port.
2. Set up a virtual serial port? No idea if this is a thing.
3. Internalize the serial-to-midi conversion/TX to my Grasshopper/Firefly setup. I don't really know what this entails.
Any thoughts?Thanks as always for all of your digital trailblazing...

In order to use Geometry Gym components in Grasshopper, please run Rhino command sdrZZLicenseRequest to request free trial license.
In order to use StructDrawRhino components in Grasshopper, please run Rhino command ssiSAPZZLicenseRequest to request free trial license.
Step 3: I double click ssiBake icon and my SAP2000 V15 opens but there is no model in SAP.
I get the following Rhino command message:
Baking Structure....
SAP model updated via COM. Axis Count: 0 Node Count: 0 Elem Count: 0 Section Property Count: 0 List Count: 0.
Data not copied to Clipboard for validation by user
Step 4: If I right click on ssiBake icon and select “Open Model in SAP” it asks for a *.sdb file.
Hope you can help. Thanks again.…

Hi Matthew, Thanks for such a swift response and sorry for the false alarm. After reinstalling Karamba the examples open without a problem.
I hoped that the examples will clarify something, unfortunately you do not use Beam Resultant Forces' output as a source of optimization criteria/objective there.
I am still having problem with the fact that Beam Resultant Forces component gives a list of zeros as a 1st output till it finishes calculation.
This is my case: 1. Karamba calculates normal forces in elements that are in the mast's traversal plane (mast sections, spreaders and wires (shrouds)). 2. Normal forces in forestays and backstays are calculated analytically elsewhere. 3. Having the normal forces in the wires, the algorithm selects the wires' diameters (having given the wires catalogue), calculates their weights and centers of gravity. 4. Objectives are: minimizing the mass and minimizing the VCG (vertical centre of gravity). They are convergent, but constraint (minimal sail area) is dealing with it. 5. The thing is that normal forces from Karamba and calculated analytically arrives at different times (Karamba need a bit more time). I tried to delay the other data (till Karamba finishes calculation) with Data Dam, Anemone's Time Buffer, Phyton/C#/VB components, but all of them caused that Octopus/Wallacei weren't working correctly.
Any idea comes to your mind how this problem might be solved?
Thanks, Mikołaj…

example file with my DWG file that I've exported from Revit into Rhino, but I'm having a few issues with the geometry.
A few problems that I'm having with this:
1. I can reference the surfaces to breps by selecting objects (walls, roofs, windows, etc.) that are associated with the imported layers no problem, but cannot create zones from breps
2. Getting this error, "Data conversion failed from brep to surface" when flipping the floor.
3. Window geometry is different in Revit than how they are recognized in HB, what is the best way to make the windows workable in HB?
Any suggestions to help me get started with simulation for this building would be greatly appreciated! Links to my dwg file, gh file, and rhino file I'm working with are down below.
Thanks in advance!

ugh information (whether coming from environmental analysis or any kind of database), extracting and managing informations for construction processes all require an understanding of data structures in order to build seamless design-to-construction pipelines. Through visual scripting in Grasshopper (Generative modeling plug-in for Rhinoceros) participants will learn how to build and develop parametric data structures (from basic simple lists to complex data trees), data-driven geometry and envelopes and how to extract relevant informations from such models for construction processes. Participants will also develop a personal envelope project and its full design-to-construction pipeline.

an external test suite.
We have a lot of parameters we want to test with, so doing so in Rhino is cumbersome.
To this end, we've experimenting to run Rhino/Grasshopper with a number of ways:
- 1) Using the COM interface, to create Rhino, load grasshopper then run tests
- 2) Exposing Rh/Gh internals using WCF via a Rhino command, which starts off WCF, then run tests
- 3) Exposing Rhino/Grasshopper internals using .Net remoting, again via a Rhino command
We've tried -1) that seems to be a dead end, limited access to Rh/Gh
We've tried -2) that works but raises an error in the WCF server stating that RhinoCommon is not available (see attached image). I've tried copying dll's from the Rhino installation to the running wcf directory, but that does not help.
Todo -3) We've still got to try this method.
I've googled similar entries in the forums:
http://www.grasshopper3d.com/forum/topics/how-can-i-use-grasshoper-externally
http://developer.rhino3d.com/api/rhinoscript/introduction/external_access.htm
Does anyone know why -2) wcf fails or if .net remoting will work successfully.
Or indeed if there are other options to address our use case?
Many thanks,
Milan…
