首先給構件族建立一個材質引數，然後讓族的材質使用該引數，即可直接用引數化的過程改變材質

建立某顏色的材質

class MaterialColor
{
    public Material materialTest;
    public Document document;
    public MaterialColor(Document document) => this.document = documentpublic void AddColor()
    {
        Transaction transaction = new Transaction(document);
        transaction.Start(
 
"改變顏色");
        materialTest = document.GetElement(Material.Create(document, "測試材質")) as Material; //建立材質
        materialTest.Color = new Color(255, 255, 0); //更改顏色
        transaction.Commit();
     }
}

然後直接將建立的新的Material賦予引數即可
