Autodesk.Revit.DB.Surface是一个表示Revit模型中的表面的类。它包含表面的几何形状和属性。
// 创建一个平面表面
Plane plane = Plane.CreateByNormalAndOrigin(XYZ.BasisZ, XYZ.Zero);
FootPrintRoofType roofType = doc.GetElement(new ElementId(123)) as FootPrintRoofType;
FootPrintRoof roof = FootPrintRoof.Create(doc, roofType.Id, level.Id, outline);
SketchPlane sketchPlane = SketchPlane.Create(doc, plane);
ModelCurveArray modelCurves = roof.FootPrint.GetCurveLoops();
ModelCurveArrayArray modelCurvesArray = new ModelCurveArrayArray();
foreach (ModelCurve modelCurve in modelCurves)
{
ModelCurveArray modelCurveArray = new ModelCurveArray();
modelCurveArray.Append(modelCurve);
modelCurvesArray.Append(modelCurveArray);
}
RoofType roofType = RoofType.Create(doc, "NewRoofType");
RoofBaseConstraint constraint = new RoofBaseConstraint(sketchPlane);
RoofSurface roofSurface = RoofSurface.Create(doc, modelCurvesArray, roofType.Id, constraint);
Surface surface = roofSurface.GetSurface();
if (surface != null)
{
double area = surface.Area;
bool userControlled = surface.UserControlled;
ElementId materialId = surface.MaterialId;
}
以上代码展示了如何创建一个平面表面,并使用它的属性来调整模型的外观和行为。注意代码中包含的元素ID和对象可能需要根据实际情况进行调整。
