    Dear All,

    I have a shape which is over a instance , the shape's bBox is apply
    to level 0 coordinate ,i.e (5.075:3.16 5.335:3.52),
    I want the bBox converts into the instance's coordinate . It's
    similar to Edit-In-Place , But the instance is Read-Only .
    ;; Convert bBox from Top to Bottom

    How to do it ?

    Thank you,

    You can use the geTransformUserBBox() function, supply the bounding
    box as the first
    argument and the "transform" as the second, this can be obtained from
    the instance -
    for example, if the instance is selected, you can do:

    so all together it would be:

    geTransformUserBBox(list(5.075:3.16 5.335:3.52)
    => some_new_bbox

    Dear Davis,

    ==> some_new_bbox is not what I want , when I open the instance , the
    some_new_bbox is not same as in the location.
    I want is like push some_new_bbox into the instance ,
    e.g. I draw a rectangle shape(On level 0) over the instance (On
    Level 1), I don't need to open the instance in another cellview ,
    Just liker using Edit-In-Place, the some_new_bbox is transformed
    inside the instance.
    When I open the instance , using the some_new_bbox to draw a rectangle
    shape .

    Thank you,
