List of materials as a field in tables

Antonio_ClavelArqu — Wed, 17 Dec 2025 22:09:20 GMT

Hello everyone,

I have a need that I haven't been able to resolve.

For the project documentation, I need to have information about the layers of materials in the construction elements.

I can get that list and the thicknesses of each layer using the “bill of materials” tag.

But in the schedules, when I call up the material list parameter, neither thicknesses nor line breaks are included.

I need a column to appear in the table with the information formatted as follows:

B04

0,20

0.02 m - Cerámico - Pavimento
0.01 m - Morte de regularización / autonivelante
0.07 m - Formación de pendiente/rellenos
0.01 - Plástico - Composite

I also can't find a way to call up that list of materials from the expressions in the properties editor. So I can't display that label information in the schedules.

Operating system used: Windows

Hi,

If I understood correctly, you want to display a composite name and each part of it plus the thickness in a different field.

To achieve that you can have something similar to this in the schedule fields, on the Components schedule:

Composite structure - you can tick the Show Headline so it groups them nicely, then the name of the building material (it will list each of them) and component thickness.

I hadn't thought of using a list of components instead of elements.

The problem remains that I need it to be a single field, as I want to use it for tables that serve as graphic legends for the plans.

We need something like this:

But in this case, we get something like this, with the plan and section views multiplied by the number of layers that make up the composite:

We understand that this may be a very specific use case for global use, but we don't see it as something very unusual in our environment either.

Well if you want to use it for a legend, why not resort to keynotes? (if you use a version of AC later than 27). Unfortunately I am not familiar with them yet to indicate how to achieve that.

Keynotes in their current state are not very useful. They are independent objects that do not add information to the model or read information from it.

We link that information to the compounds/elements as I mentioned in this other post: https://community.graphisoft.com/t5/Documentation/Keynotes-vs-Properties-vs-Simple-Text/m-p/682971/highlight/true#M69253

Thank you for your responses. We continue to look for ways to improve our workflows.

I started building a wall schedule object with GDL. The way it worked is you would first export a schedule - similar to ones in your example to a csv file, then read the csv file with GDL and rebuild the composite makeup from building material and thickness information. If you want a very specific output GDL is the way to go. Not to mention that any scheduling with GDL is way faster than interactive schedules.
