Marking of Elements via Linefence in MSTN-Connect Update 14

i'am trying to convert my Programms from MSTN 8i to MSTN Connect. Below is my Code for just Marking of Elements with overlapped LineFence.

A LineFence is a FenceShapeElement but it looks like a Line.

It worked really good in MSTN 8i and we need it in MSTN-Connect. My Accudraw is Enabled. I have no locks. View Depth is frm -1000 to 1000. 
My Elements have a Z-Koordinate=0. My Problem is, that no Elements will be found and marked. 

I will be grateful for your the help. Thanks.

Hier is DGN with Elements
