Move pipe problems

[beckhans]

   I  want to change user selected pipe 's  offset (-50mm) by using Revit 2014 API. I write a loop as blow.

foreach (var element in sel.Elements)
                {
                    if (element is Pipe)
                    {

                        var s = element as Pipe;
                        var lCurve = s.Location as LocationCurve;
                        lCurve.Move(new XYZ(0, 0, -50 / 304.8));
                    }
}

 But when the code Run. The Real offset was -600mm.I debug the code and found when a pipe's offset changed,other pipes who connect to 

this pipe were also changed.Because User selected 12 pipes .So the offset were 12*-50=-600;

 Please give me some suggest to do this .

Dear Beckhans,

I would suggest trying to use the ElementTransformUtils.MoveElements method and passing in all of the selected element ids in one single call instead of looping over them one by one.

I hope this helps.

Cheers,
