"Hi Jorge, As far as I know, it should be compatible with Firefly... but I haven't run specific tests on it.  However, my understanding of the RedBoard is that it is almost identical to the Uno (and/or Duemilanove) both of which work just…"

"That is it precisely! I took Jasons workshop at Texfab 5 and I got a little understanding of how to code arduino's, so that is a route. My goal is to move 16 motors all with reset pins for zeroing. I will be tied up with Arduino boards as it is…"

"Hi Nathan, If I understand correctly, what you're saying is you have some motors that you want to control via the Quad Stepper Firmata... and you have some reset buttons (sensors) that you want to read from using the standard Firefly Firmata.…"

What is missing in generative design?

Here is a link to a very great blog post by Sivam Kirsh.  it is a review of the ”Design the Dynamic”  design conference in Melbourne.  He brings up some great points to consider with the new generative design tools we are all experimenting with.  Jump in on the discussion:

Volatile Data Management

Data Inheritance

Data is stored in parameters (either in Volatile or Persistent form) and used in components. When data is not stored in the permanent record set of a parameter, it must be inherited from elsewhere. Every parameter (except output parameters) defines where it gets its data from and most parameters are not very particular. You can plug a double parameter into an integer source and it will take care of the conversion. The plugin defines many conversion schemes but… Continue

Data Matching Explained

Data matching is a problem without a clean solution. It occurs when a component has access to differently sized inputs. Imagine a component which creates line segments between points. It will have two input parameters which both supply point coordinates (Stream A and Stream B). It is irrelevant where these parameters collect their data from, a component cannot "see" beyond its in- and output parameters:

As you can see there are… Continue

Persistent Data Management

How to set and alter persistent data records

Types of Data

Parameters are only used to store information, but most parameters can store two different kinds;

Volatile and Persistent data. Volatile data is inherited from one or more source parameters and is destroyed (i.e. recollected) whenever a new solution starts. Persistent data is data which has been specifically set by the user. Whenever a parameter is hooked up to a source object the… Continue

Hi Scott,

I am sorry to reach out to you in this forum, but I was not sure who I could direct this question to. I use a 3dconnexion space mouse and have been in contact with the manufacturer asking for a driver for Rhino 5, this was their response:

Rhino 5 beta is still a work in progress. Rhino provides an add-in on there website. With Rhino still in Beta if the add-in needs to be modified they will provide an update to the add-in.

If you have any news or can direct the team to provide an add-in on the website... it would be much obliged.


Thank you for your time.

Hi Scott

Is it possible to put some kind of sticky in the samples and examples forum that says do not post questions HERE as seem to have been quite a few question posted in there recently by newbies to Grasshopper.

Thanks Matt
