Transformation rules for familyinstance

I am trying to transform a familyinstance. It either does not respond at all to

ElementTransformUtils.RotateElement

ElementTransformUtils.MoveElement

or responds illogically. When I apply the abovementioned methods to an adaptive instance obtained from,

AdaptiveComponentInstanceUtils.CreateAdaptiveComponentInstance

everything reacts logically. However in the case of a familyinstance, it seems that other rules apply. Which methods can I use to obtain Rotation and Translation of a familyinstance? Should I use

fi.Location.Rotate

fi.Location.Move

instead?

Hi,

ElementTransformUtils.MoveElement is use to displace a element from one location to another location.

You can use this as below

1st : Lp = FamilyInstance Location Point.

You want to move at new Point that is newPosition;

after that do it like.

XYZ newposition=new XYZ(1,1,1);

XYZ oldPosition=Lp;

XYZ MovePosition=null;

MovePosition= newposition- oldPosition

ElementTransformUtils.MoveElement(Doc, Elemnetid, MovePosition)

i hope this will work fine.
