Autodesk.Revit.DB.DrawLayer
是Revit API中的一种类型,代表绘图层。每个绘图层都有自己的画笔颜色和线型,还可以指定透明度等属性,控制在Revit中的图形绘制。
DrawLayer()
: 创建一个新的绘图层对象。Color
: 获取或设置绘图层的绘画颜色。Pen
: 获取或设置绘图层的画笔属性。LineWeight
: 获取或设置绘图层的线宽。LinePattern
: 获取或设置绘图层的线型。Transparency
: 获取或设置绘图层的透明度。Plot
: 获取或设置绘图层的可打印属性。Dispose()
: 释放当前对象占用的所有资源。Equals(Object)
: 确定指定对象是否等于当前对象。GetHashCode()
: 返回当前对象的哈希代码。GetType()
: 获取当前实例的类型。ToString()
: 返回当前对象的字符串形式。//创建新的绘图层
DrawLayer drawLayer = new DrawLayer();
//设置绘图层属性
drawLayer.Color = Colors.Red;
drawLayer.LineWeight = LineWeight.Bold;
drawLayer.LinePattern = LinePattern.DashDot;
drawLayer.Transparency = 50;
drawLayer.Plot = false;
//在某个元素上画线
Line line = Line.CreateBound(new XYZ(0, 0, 0), new XYZ(10, 10, 0));
ElementId elementId = new ElementId(123); //假设是一个有效的元素ID
View view = doc.GetElement(elementId) as View; //获取元素所在的视图
view.Document.Create.NewDetailCurve(view, line); //在视图上创建新的线元素
doc.Regenerate();
//获取该线元素并设置其颜色和线型
ElementId lineId = view.GetFirstDependency(line).Id;
OverrideGraphicSettings overrideGraphicSettings = new OverrideGraphicSettings();
overrideGraphicSettings.SetProjectionLineColor(drawLayer.Color);
overrideGraphicSettings.SetLineWeight(drawLayer.LineWeight);
overrideGraphicSettings.SetLinePatternId(drawLayer.LinePattern.GetPatternId());
view.SetElementOverrides(lineId, overrideGraphicSettings);
//设置元素的绘图层
Element element = doc.GetElement(lineId);
ElementCategoryFilter elementCategoryFilter = new ElementCategoryFilter(BuiltInCategory.OST_Lines);
FilteredElementCollector filteredElementCollector = new FilteredElementCollector(view.Document).WherePasses(elementCategoryFilter).OfClass(typeof(GraphicsStyle));
foreach (Element graphicsStyle in filteredElementCollector)
{
if (graphicsStyle.Name == drawLayer.LinePattern.Name)
{
Parameter parameter = graphicsStyle.get_Parameter(BuiltInParameter.LINE_STYLE);
element.get_Parameter(BuiltInParameter.ELEM_CATEGORY_PARAM_MT).Set(graphicsStyle.Id);
element.get_Parameter(parameter.Id).Set(drawLayer.LinePattern.GetGraphicsStyleType());
break;
}
}
doc.Regenerate();
上述代码创建一个新的绘图层,设置了其颜色、线型、线宽和透明度等属性。然后在某个视图上添加一条线,并设置该线的颜色、线型和线宽。最后将该线所在的线样式设置为绘图层的线型。
