revit二次开发构件上色

首先给构件族创建一个材质参数，然后让族的材质使用该参数，即可直接用参数化的过程改变材质

创建某颜色的材质

class MaterialColor
{
    public Material materialTest;
    public Document document;
    public MaterialColor(Document document) => this.document = documentpublic void AddColor()
    {
        Transaction transaction = new Transaction(document);
        transaction.Start("改变颜色");
        materialTest = document.GetElement(Material.Create(document, "测试材质")) as Material; //创建材质
        materialTest.Color = new Color(255, 255, 0); //更改颜色
        transaction.Commit();
     }
}

然后直接将创建的新的Material赋予参数即可
