如何通过revit api将图元放置在墙上
如何通过revit api将图元放置在墙上
提问于 2019-08-16 19:46:09
我想把一些元素一个接一个地放在墙上。
我在模型中的墙上放置了一些元素。我能够放置第一个元素，但不知道如何放置第二个和连续的元素。我已经上传了我所取得的成就和我想要做的下一步的源代码和图像。该族不是主体族。
public static FamilyInstance PlaceFamily (Wall wall, Family family, Document document)
{
FamilySymbol symbol = null ;
foreach (ElementId s in family.GetFamilySymbolIds())
{
symbol = document.GetElement(s) as FamilySymbol;
break;
}
LocationCurve locationCurve= wall.Location as LocationCurve;
XYZ point= locationCurve.Curve.GetEndPoint(0);
Transaction transaction2 = new Transaction(document, "place Instance");
transaction2.Start();
if (!symbol.IsActive)
symbol.Activate();
FamilyInstance instance = document.Create.NewFamilyInstance(point, symbol, StructuralType.NonStructural);
transaction2.Commit();
return instance;
}

我找到了我的解决方案。我只需要找到下一个定位点。这就是我是如何做到的。
XYZ p0 = locationCurveOfWall.Curve.GetEndPoint(0);
XYZ p1 = locationCurveOfWall.Curve.GetEndPoint(1);
XYZ vectorAlongTheWall = new XYZ(p1.X - p0.X, p1.Y - p0.Y, p1.Z - p0.Z);
XYZ normalizeVectorAlongTheWall = vectorAlongTheWall.Normalize();
XYZ oldStartPoint = p0;
int n2 = (int)Math.Round(wallLength / 4); // 4 is the width of the element
Transaction transaction2 = new Transaction(document, "place Instance");
transaction2.Start();
FamilyInstance instance2 = document.Create.NewFamilyInstance(oldStartPoint, symbol, wall, StructuralType.NonStructural);
for (int j = 1; j < n2 - 1; j++)
{
XYZ newStartPoint = new XYZ(oldStartPoint.X + 4 * normalizeVectorAlongTheWall.X, oldStartPoint.Y + 4 * normalizeVectorAlongTheWall.Y, oldStartPoint.Z + 4 * normalizeVectorAlongTheWall.Z);
instance2 = document.Create.NewFamilyInstance(newStartPoint, symbol, wall, StructuralType.NonStructural);
oldStartPoint = newStartPoint;
}
transaction2.Commit();请建议一个更好的方法。
