How to add materials to document

Anonymous — Wed, 17 Apr 2019 15:12:34 GMT

Hi all, How can I implement the arrow (adds materials to document) as circled in the attached file using API, and then I can use the material in my model.

Thanks,

You can get material from active Revit document with FilteredElementCollector and Linq.

In this code snippet, I showed how to get a material from the document and apply this material to a wall layer.

// You can get any material in the document with just material name
Material material = new FilteredElementCollector(doc).OfClass(typeof(Material)).Cast<Material>().Where(q => q.Name == "Material Name").First();

// Choose a wall from document
Wall wall = doc.GetElement(uidoc.Selection.PickObject(ObjectType.Element)) as Wall;
// Get wall layers
IList<CompoundStructureLayer> layers = wall.WallType.GetCompoundStructure().GetLayers();

foreach (var layer in layers)
{
    // Choose which layer you want to change
    if (layer.Function == MaterialFunctionAssignment.Finish2)
    {
        // Set layer material
        layer.MaterialId = material.Id;
        // Set Layer thickness
        layer.Width = 5; //Feet
    }
}

I hope this helps,

Recep.

Thanks for your reply. I might not state my question clearly. From the Revit UI, Manage -> Settings -> Materials, the upper panel of the pop-up window shows all the materials which can be used in the current project document. However, I want to use the material listed in the bottom panel, for example, “Concrete C45/55”. I have to press the arrow button as shown in the attached file to import “Concrete C45/55” to the current document, and then I can use it in my model. What I want is to import “Concrete C45/55” through API.

I tried the method you suggested:

Material material = new FilteredElementCollector(doc).OfClass(typeof(Material)).Cast<Material>().Where(q => q.Name == "Material Name").First();

But it can only get the materials in the upper panel.

There should be API methods to accomplish this. But I could not find the solution. Could someone please help me on this?

I have encountered the same problem. Do you have a solution？

I don't think much of that dialogue is exposed to the API in terms of importing materials from the external library.

However, the easiest way by far to import materials is to load a family containing them and then delete the family.

This is also a way, thank you😁
