Revit二次开发之实现按梁高给给梁设置不同的颜色

按梁高给给梁设置不同的颜色

在没有插件的情况下，要给不同梁高的梁设置不同的颜色需要在过滤器里面设置。有了这个样的插件以后就可以更加方便的设置了。下面上代码

            //获取实体
            FillPatternElement fp = fillFilter.First(m => (m as FillPatternElement).GetFillPattern().IsSolidFill) as FillPatternElement;
            OverrideGraphicSettings ogs = doc.ActiveView.GetElementOverrides(id);
            //填充图案
            ogs.SetProjectionFillPatternId(fp.Id);
            //颜色
            ogs.SetProjectionFillColor(color);
            //应用到视图
            doc.ActiveView.SetElementOverrides(id, ogs);
        }
    }
}

效果如下：
