I am getting an error when I try to change the value of a feature's Rotation Value. I have a schematic feature that I would like to rotate by changing the field's ROTATION value, but everytime I try to set the new value I get this error. "Error HRESULT E_FAIL has been returned from a call to a COM component"

Here is the part of the code where I set the value

ISchematicRelationController controller = new SchematicRelationControllerClass();
var parentContainer = controller.FindParent(duct);
if (parentContainer == null) {
   var rotIdx = parentContainer.Fields.FindField("ROTATION");
   var idx = duct.SchematicElement.Fields.FindField("ROTATION");
   if (rotIdx > -1) {
      Duct.SchematicElement.Value[rotIdx] = 45;
      parentContainer.Value[rotIdx] = 65; ------> this is where the exception occurs
                    }

Reset to default

It turned out this field took double values so the answer was to set it as follows:

Duct.SchematicElement.Value[rotIdx] = 45;
  parentContainer.Value[rotIdx] = 65d; or 65.0
