You need at least SR 12.


This error seems like an install issue- maybe inputs wrong? Occurs on both Poly and Nurbs nodes. First time user. Can you assist? Installed 2.0 Thanks!

"1. Solution exception:Could not load file or assembly 'Pachyderm_Acoustic, Version=, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."

Hi Mark,
It might be an installation issue, but I doubt it. It's more likely that you haven't loaded the rhino plugin yet.

Try closing rhino, and opening it again. Before opening grasshopper, type 'Pachyderm_Acoustic' into the command prompt, and press enter.

The pachyderm for rhino interface will appear.

Now open grasshopper, and try what you were doing again. Let me know if that works.

The yep plugins talk to each other, so you need to have both loaded for grasshopper.


Anyone running Pachyderm in Rhino 6? 

Having a hard time installing for some reason (its probably just me!)


Even I had problems with the Pachyderm running on Rhino 6.

Did you receive any update from Arthur regarding the beta version?

Hoping to receive a positive response.

Hi David,

It's not you. I have a beta version for the rhino 6 install.

Email me if you want it.


Hi Arthur,

I have been working on an acoustic project for my master thesis, even I had problems with the Pachyderm running in Rhino 6. 

I would like to have the beta version for rhino 6 if possible, it could be of great help for me. 

Hoping for a positive response. 

Thank you in advance.  

Hello Everyone, I have installed Pachyderm. But when I open the folder of the program in "Program Files", the Rhino Plug-in file does not exist. I have tried to rerun the installation and chose the repair option but it did not solve the problem. Has anyone had this problem before?

Hi Behdad,

Does the plugin run in Rhino?

The actual plugin is installed in its own folder in program files.

C:\Program Files\Pachyderm_Acoustic\

I can't remember, but I think it may also let you choose the installation location.
