我刚刚开始使用 Revit API 很短的时间,并且一直在为这个问题挠头。我想使用“通用模型自适应”族模板创建一个包含实体形式的族。但是,似乎我无法使用在家庭文档中创建扫描
Autodesk.Revit.Creation.FamilyItemFactory.NewSweep()
因为我不断收到以下异常:
Autodesk.Revit.Exceptions.InvalidOperationException
The attempted operation is not permitted in this type of family.
这个错误的原因是什么?为什么我一直在处理新创建的家庭文档,但不允许操作?这是我的代码:
// sweepPath is a CurveByPoints instance.
if (null != sweepPath)
{
acTrans.Start("Cable");
// create a circle as bottom shape for the cable
IList<XYZ> points = sweepPath.GeometryCurve.Tessellate();
XYZ center = points[0];
Plane workingPlane = Plane.CreateByNormalAndOrigin(XYZ.BasisZ, center);
Arc bottomShape = Arc.Create(workingPlane, _radius, 0, 2 * Math.PI);
// create profile
CurveArray curveArray = new CurveArray();
curveArray.Append(bottomShape);
CurveArrArray arrArray = new CurveArrArray();
arrArray.Append(curveArray);
SweepProfile profile = _rvApp.Create.NewCurveLoopsProfile(arrArray) as SweepProfile;
// create path
XYZ sweepPathDirection = points[1] - points[0];
double angle = sweepPathDirection.AngleTo(XYZ.BasisZ);
XYZ direction = sweepPathDirection.CrossProduct(XYZ.BasisZ);
Line axis = Line.CreateUnbound(center, direction);
ElementTransformUtils.RotateElement(familydoc, sweepPath.Id, axis, angle);
CurveArray path = new CurveArray();
path.Append(sweepPath.GeometryCurve);
// create sketch plane
Plane plane = Plane.CreateByNormalAndOrigin(new XYZ(10, 0, 0), refPointArray.get_Item(0).Position);
SketchPlane pathPlane = SketchPlane.Create(familydoc, plane);
// create the cable
// Sweep sweep = familydoc.FamilyCreate.NewSweep(true, curveArray, pathPlane, profile, 0, ProfilePlaneLocation.Start);
ReferenceArray refArray = new ReferenceArray();
refArray.Append(sweepPath.GeometryCurve.Reference);
Sweep sweep = familydoc.FamilyCreate.NewSweep(true, refArray, profile, 0, ProfilePlaneLocation.Start);
acTrans.Commit();
}
编辑1:我首先认为家庭文档没有激活,因此我尝试了
Application.OpenDocumentFile(file_path_for_my_family_document);
但它没有成功。即使我尝试了从 SDK 创建家庭文档扫描的示例代码,同样的错误仍然会发生。
