get_BoundingBox in subTransaction with RollBack

1

Hello guys,
is there any way to bypass this one?

Basically the idea is to

  • create an empty sheet

  • place viewports

  • get boundingBox of each viewport -> I need Points
    This way I can get whole BB with viewport title
    I don’t really need to create this sheet with all viewports so that’s why there is a rollback.
    But still can’t bypass
    .get_BoundingBox(view)

    TransactionManager.Instance.EnsureInTransaction(doc)
    trans = Autodesk.Revit.DB.SubTransaction(doc)
    trans.Start()

      	try:
  		if Viewport.CanAddViewToSheet(doc,sheet.Id,v.Id):
  			vp = Viewport.Create(doc,sheet.Id,v.Id,l.ToXyz())
  			bounding = vp.get_BoundingBox(vp)
  			minPoints.append(bounding.Min.ToPoint())
  			maxPoints.append(bounding.Max.ToPoint())
  			
  	except Exception, e:
  		outList.append(e.message)
  	trans.RollBack()
  	TransactionManager.Instance.ForceCloseTransaction()

I can get points using:
vp.GetBoxOutline().MinimumPoint.ToPoint()
but these points don’t take into account viewport title ;/

Thanks :slight_smile:

GetBoxOutline() & GetLabelOutline() methods did the trick (without BoundingBox).
Still, it would be nice to know how to do this using BB :slight_smile:
