【Revit】族及项⽬下创建拉伸，融合，放样
族：
Ps. 函数⾥⾯的ConvertToInternalUnits这个⽅法，是将毫⽶单位转成recit内部单位，这个转换可以⾃⾏转换，代码这边没有贴出来。
public static Element GetHostInstance(Document doc, CurveArrArray curveArrs, XYZ faceNormal, double start, double end, bool IsSolid = true)
{
Element element = null;
#if Revit2018
element = doc.FamilyCreate.NewExtrusion(IsSolid,
curveArrs,
SketchPlane.Create(doc, Plane.CreateByNormalAndOrigin(faceNormal, new XYZ(start * faceNormal.X,
start * faceNormal.Y, start * faceNormal.Z).ConvertToInternalUnits())),
好好学习天天向上英语Math.Abs(end - start).ConvertToInternalUnits());beatboxer
obvious是什么意思#elif Revit2019
element = doc.FamilyCreate.NewExtrusion(IsSolid, curveArrs,
SketchPlane.Create(doc, Plane.CreateByNormalAndOrigin(faceNormal, new XYZ(start * faceNormal.X, start * faceNormal.Y, start * faceNormal.Z).ConvertToInternalUnits())), Math.Abs(end - start).ConvertToInternalUnits());

element = doc.FamilyCreate.NewExtrusion(IsSolid, curveArrs,
SketchPlane.Create(doc, new Plane(faceNormal, new XYZ(start * faceNormal.X, start * faceNormal.Y, start * faceNormal.Z).ConvertToInternalUnits())),
Math.Abs(end - start).ConvertToInternalUnits());

补充PS：拉伸⽅向貌似和轮廓线的⽅向有关系。
项⽬：
先来⼀段项⽬⽂档下，拉伸的测试。复制可直接⽤（需要⾃⼰开事务）：
public static void CreateCubicDirectShape(Autodesk.Revit.UI.UIApplication app)
{
List<Curve> profile = new List<Curve>();
double edgeLength = 2.0;
XYZ p1 = new XYZ(edgeLength, 0, 0);
XYZ p2 = new XYZ(edgeLength, edgeLength, 0);
danny moderXYZ p3 = new XYZ(0, edgeLength, 0);
XYZ p4 = new XYZ(0, 0, 0);
profile.Add(Line.CreateBound(p1, p2));
profile.Add(Line.CreateBound(p2, p3));
profile.Add(Line.CreateBound(p3, p4));
profile.Add(Line.CreateBound(p4, p1));
CurveLoop curveLoop = CurveLoop.Create(profile);
SolidOptions options = new SolidOptions(ElementId.InvalidElementId, ElementId.InvalidElementId);
Solid cubic = GeometryCreationUtilities.CreateExtrusionGeometry(new CurveLoop[] { curveLoop }, XYZ.BasisZ, 10);
// create direct shape and assign the sphere shape
DirectShape ds = DirectShape.CreateElement(app.ActiveUIDocument.Document, new ElementId(BuiltInCategory.OST_Floors), app.ActiveAddInId.GetGUID().ToString(), ""); ds.AppendShape(new GeometryObject[] { cubic });
edgeLength = 3.0;
p1 = new XYZ(edgeLength, 0, 0);
p2 = new XYZ(edgeLength, edgeLength, 0);
p3 = new XYZ(0, edgeLength, 0);
p4 = new XYZ(0, 0, 0);
profile = new List<Curve>();
profile.Add(Line.CreateBound(p1, p2));
profile.Add(Line.CreateBound(p2, p3));
profile.Add(Line.CreateBound(p3, p4));
profile.Add(Line.CreateBound(p4, p1));
var curveLoop2 = CurveLoop.Create(profile);
var cubic2 = GeometryCreationUtilities.CreateExtrusionGeometry(new CurveLoop[] { curveLoop2 }, -XYZ.BasisZ, 5);
ds.AppendShape(new GeometryObject[] { cubic2 });
}
以下是正式代码：
正式代码没有了。。。因为⽬前没有找到在项⽬下空⼼剪切的实现⽅法，那就没必要继续研究下去了。。
