Custom materials usage and import

kency — Tue, 17 Sep 2024 11:20:55 GMT

Hello all,

How can we import a custom material /texture for walls and use the custom material through Add-On code? Is it possible to simply provide the URL of the texture?

Update -> Have added a screen shot of the custom image import for materials that I mentioned above.

Thank you,

Kency

You can do it with the API, but you need to implement a couple of steps to achieve the final result:

Move the texture file to the embedded library (url reference doesn't work).
Create a Surface attribute that references the texture file from the embedded library.
Apply the created Surface attribute on the corresponding parameter of the wall.

Thank you @Viktor Kovacs .

1. Is there any folder within the downloaded ArchiCAD application? Or the only way to import is through the ArchiCAD UI?

2 and 3. Any example that you know of is available for the same in the DevKit?

No out of the box solution, but you may check these example add-ons in the Development Kit:

In the LibPart_Test example add-on there is an example for retrieving the physical location of the embedded library. You just need to copy your texture file into this location. A library reload may be needed.
In the Attribute_Test example you can find codes to create attributes. There is no example for creating surfaces, but it's very similar to other attributes.
In the Element_Test example there are a lot of codes as an example for modifying elements.
