Hello Pachyderm Users,
We are going through an exciting period, including the startup of an organization to support the growth of Pachyderm, and extend the educational agenda of the project. In the next few weeks, we will be submitting our long-form 501(c)3 application, which will give us the rights of a not-for-profit organization established in the state of Connecticut. As part of the transition, we are phasing out the old website. The new site will be up in the next few weeks, and you can find it at:
 
 
We are looking forward to the next phase of this project, and we hope that you will be there with us to learn and continue to support us!
 
kind regards,

Hi Prakati,

In the latest version, I removed the "Apply" button by popular request. Instead, as soon as you click a library item, it applies it to the selected layer automatically.

For some, that was less confusing.

But is the issue actually that you don't have a library? It's hard to know why without looking at your computer. Most likely, the file is missing. Here is where it would be normally:

C:\Users\[Username]\AppData\Roaming\Pachyderm

In case it is indeed missing, please take mine: Pach_Materials_Library.txt

There isn't a whole lot in there - it is up to the users to fill it. But hopefully this helps.

Hi Arthur,

I've find an issue about "mapping surface".

When i create the output, the result of the mapping corresponds to higher values to the ones calculated with hybrid method.

Practically, the results i obtain correspond to the ones i would have with a source of at least 120 dbA SWL, even if i inserted a "speaking person".

Moreover, i can't create output for all the parameter that are not SPL.

Can you help me?

Thank you in advance,

Fabio

Hi David,

The apply button is gone because clicking the library entry applies it's parameters automatically. This was requested by other users.

Regarding applying materials in grasshopper, it is fine by layer ID, and layer ID is assigned as the zero based order of appearance on your layer tab in rhino. You need one ID in GL per item in GG. Make sure your input is in list form, not tree form.

Hi Arthur,

I am trying apply material and I am having the same problem of Sandrine. If I click on the library, I can't choose apply, the button is not there like the tutorial. I am also curious to know how to apply material throug grasshopper canvas. And Finally, to be sure about the applied material, how can I check its application to a surface?

Thanks in advance

David

Where to download this plugin

Comment by Arthur van der Harten on September 24, 2018 at 4:35pm
Hi Sandrine,
To apply the materials as before, just click it in the library. It sets automatically.

Just responding to some feedback.

Camila, your issue should be resolved now as well.

Arthur
