DatumPlane SetCurve problems

[bosborne]

I am trying to use DatumPlane.SetCurveInView to duplicate 2d extents of grids across views. I am taking a reference view and using GetCurvesInView to get the curve to set with. This works fine for views that are essentially copies of the primary view (Same Associated Level)

But when I attempt it for plan views that are at a different level than the reference plan view, it does not work. Which makes sense....the ref curve is not at the correct elevation.

No problem, I'll use Curve.CreateTransformed(Transform.CreateTranslation(XYZ(0,0,offset))) where offset is the Z value (level elevation) of my new view minus the Z value of the reference level. But this fails for some reason. The error states that the curve must be bound and coincident with the datum plane. I tested using Curve.IsBound and that returned "True"....so how can the curve not be coincident if it was only offset in Z??

I also tried getting the start and end points of the reference curve, and creating new XYZ with the new Z value and using Line.CreateBound but that too gave me the same error.

So my question is - how do I use SetCurveInView when the reference curve is taken from a datum plane that is in a plan view at a different elevation than the plan view containing the datum plane I am trying to set.

Dear bosborne, is it possible to provide a rvt file with code example to help us to reproduce your problem? thanks

Did you ever solve this? I'm experiencing the same problem attempting to resize the DatumPlane associated with Levels

foreach (Curve cv in dp.GetCurvesInView(DatumExtentType.Model, doc.ActiveView))
{
    MessageBox.Show(cv.GetEndPoint(0).ToString() + "  " + cv.GetEndPoint(1).ToString());
}

I use this parse to read the curves, and found that it's only works in view section, and the curve is bounded by both the Z-axis and the section plane.

So edit it in South Side and East Side View (or any sections horizontal to X and Y axis) would be better.

Level level;
View southViewSection, eastViewSection;

//get these and check the view is with correct direction.

//edit the datum for X-axis
Curve datumToCurveX = level.GetCurvesInView(DatumExtentType.Model, southViewSection).First();
                datumToCurveX = Line.CreateBound(
                    new XYZ(newX0, datumToCurveX.GetEndPoint(0).Y, datumToCurveX.GetEndPoint(0).Z),
                    new XYZ(newX1, datumToCurveX.GetEndPoint(1).Y, datumToCurveX.GetEndPoint(1).Z)
                );
                level.SetCurveInView(DatumExtentType.Model, southViewSection, datumToCurveX);
//do Same for Y-axis
