Grasshopper-Archicad connection not connecting?

Anonymous — Thu, 11 May 2023 09:05:35 GMT

Hello, I am totally new to try this feature, so I am using Archicad 23 EDU, and Rhino 6. I have installed the connection plugin, and the 'archicad' tab on grasshopper is already shown up. Then I did a test by making a slab in Archicad, and in GH I put the Slab parameter capsule, and right click on it and click something called 'extract/select a single from archicad'. Then the window of GH and Rhino were minimized only for a couple seconds, and then it went back again to the GH window, and nothing happened. Seems like I cannot extract or I think the connection is not working. Can somebody help me please? Thank you!

Hello,

I hope you managed to figure out how to get along with it by yourself. If no, let me share this youtube playlist with you, that should take you through all the steps of how to get started with Grasshopper (and the Live connection):
https://www.youtube.com/playlist?list=PLnXY6vLUwlWUfX-KiXfMC-X9_-IjzZGcl

Anyhow, in this specific case, if you want to reference an existing slab inside ARCHICAD to be liked to a "slab container" component in grasshopper, first you will need to start the connection from the Grasshopper Connection palette (see the video for this), and then right-click on the component, choose "select one slab in ARCHICAD", and then click a slab in ARCHICAD. If the slab was already selected in ARCHICAD before, then it may pick the selected slab automatically.

I hope this helps!

Regards,

Step one for me will be getting the ArchiCAD element/s to be displayed in Rhino via the ArchiCAD-Grasshopper add-on.
I have still not been able to do that using ArchiCAD 23 and Rhino 6 - but it was working for me with earlier versions. I must have some simple thing setup wrong. ? Connections are verifiably established but I do not see anything in Rhino.

Also, there are too many old videos out there which don't work for new versions.

Before I spend money on tutorials to figure out where I have gone wrong with my set up, does ArchiCAD 23 and Rhino 6 ( windows) work for anyone else? I read about problems like I am having but I don't see any windows users saying that it works as expected for them. ?

Have you tried to add in parameters in Grasshopper to assign your ArchiCAD elements to?

Steve,

Establishment of the connection between the two programs does not mean anything is displayed in Rhino. Did you place any ARCHICAD Node in Grasshopper and set one or more ARCHICAD Elements with it? You will see ARCHICAD stuff displayed in Rhino only if you use an ARCHICAD Node in Grasshopper to get the geometry of those ARCHICAD elements into Rhino/Grasshopper.
Like you can see it in this clip:

Hi Daniel,

I am having an issue with the connection with Rhino 7 and AC25 latest build, that happened after I uninstalled Rhino 6 this morning. The connection is detected, all the AC nodes become grey, but I am not able to send anything, and all the attribute nodes as well as any node that requires connecting with AC don't collect any data (like the GDL object library). I have deleted the connection plugin and reinstalled it, also uninstalled Rhino and re-install and nothing... quite frustrating though.
Any idea or advice?

Hi Jorge,

Did you find a solution to this?

I am having the same issue. Running Rhino 7 and AC25 on a Mac studio (M1 max chip)

Hi Jorge.

Hi Marius

I have the same problem on M1 Max.

Have you solved this issue?

Hi! @Mario Sacco @ArkMW
some anonymous help coming from GS local support send me this:

If you have a brand new mac, and install Rhino 7 only, there was a bug in the GHAC that refers to the wrong Plist file.

To solve the issue, we need to navigate to

/Users/<username>/Library/Preferences/

then rename the PLIST: "com.mcneel.rhinoceros.7.plist"
to: "com.mcneel.rhinoceros.plist"

Please note that the Library folder inside userhome is a hidden folder. You can follow this guide to access it:
https://www.lifewire.com/os-x-is-hiding-your-library-folder-2260833

hope this can help!

It works.

Both in AC24 and AC25. I just tested only few components.

Thank you @jorgebeneitez

Amazing! Thanks @jorgebeneitez for your answer! I tested it and seems to work for me! Great! I was quite disappointed with Archicad support/ Graphisoft, which was saying to wait for an eventual update with AC26... Quite nice that it can be solved very easily! 😄

Thanks for the support Jorge but in my case doesn't work, rename the file avoiding the ".7" but still no objects showing neither in AC or Rhino, besides when renaming the preferences file, a new com.mcneel.rhinoceros.7.plist file get created in same place just when closing Rhino or starting Rhino no matter what, there's always the 2 files, the one with the ".7" and the renamed without it.

Do you know any other solution please?

Regards.

Alfredo Gzz — Fri, 27 May 2022 03:46:55 GMT

I forgot to mention, I'm in AC25-3011, Rhino 7 and MBP M1 max..

Is there a way to avoid creating the com.mcneel.rhinoceros.7.plist file automatically each time I close or start the app? maybe that can solve it I think.

Aaron Bourgoin — Tue, 13 Sep 2022 19:28:29 GMT

I've been having this problem and as you say, starting Rhino Grasshopper creates a new...7.plist file. Will have to try complete uninstall reinstall for both AC25 and Rhino 7.
