Elevation View cropBox trasform can not modify orign XYZ value?

view.CropBox = sectionBox;

But orign is not changed.

why?

my code:  ref 

http://thebuildingcoder.typepad.com/blog/2012/06/create-section-view-parallel-to-wall.html?cid=6a00e...

BoundingBoxXYZ bb = wall.get_BoundingBox(null);
double minZ = bb.Min.Z;
double maxZ = bb.Max.Z;

double w = v.GetLength();
double h = maxZ - minZ;
double d = wall.WallType.Width;
double offset = 0.1 * w;

XYZ min = new XYZ(-w, minZ - offset, -offset);
//XYZ max = new XYZ( w, maxZ + offset, 0 ); // section view dotted line in center of wall
XYZ max = new XYZ(w, maxZ + offset, offset); // section view dotted line offset from center of wall

XYZ midpoint = p + 0.5 * v;
XYZ walldir = v.Normalize();
XYZ up = XYZ.BasisZ;
XYZ viewdir = walldir.CrossProduct(up);

Transform t = Transform.Identity;
t.Origin = midpoint;
t.BasisX = walldir;
t.BasisY = up;
t.BasisZ = viewdir;

BoundingBoxXYZ sectionBox = new BoundingBoxXYZ();
sectionBox.Transform = t;
sectionBox.Min = min;
sectionBox.Max = max;

return sectionBox;

to move the cropbox, you have to move the associated "ElevationSectionMarker"  (category OST_VIEWER) of the elevation

ElevSectionMarker.Location.Move(translation);

to rotate the cropbox, you have to rotate the ElevationMarker

                ElevationMarker elevation;
                Location loc = elevation.Location;
                loc.Rotate(Line.CreateBound(XYZ.Zero, XYZ.BasisZ), viewAngle);

hi，

 Rotate is OK.   I  use  ElementTransformUtils.RotateElement， is ok , too.

but

Move is not OK!

ElevationMarker is  moved Succeeded,  but CropBox.Transform.Origin is not modified!

why?

you have to move the "ElevationSectionMarker" (the element that looks like my first picture).

here's how you find that element:

List<Element> ElevSectionMarkers = new FilteredElementCollector(doc, viewPlanId)
            .OfCategory(BuiltInCategory.OST_Viewers)
            .ToList();
Element ElevSectionMarker = null; // element to find
foreach (Element elem in ElevSectionMarkers)
{
      Parameter par = elem.get_Parameter(BuiltInParameter.VIEW_NAME);
      if (par != null)
      {
                    if (string.Compare(par.AsString(), view.Name) == 0)
                    {
                        ElevSectionMarker = elem;
                        break;
                    }
       }
}
