Moving objects or drawing lines along z-axis doesn`t work in AutoCAD Architecture

[aleksandr_kpme]

I'm using AutoCAD Architecture, so it is basically for 3d modeling. Suddenly "z-filter" text appeared beside crosshair during entering any command(copy, move, distance, line and so on). I can move objects or draw lines only in X-Y plan. If moving objects in Z axis direction, object will stay on same place. If coping an object in  Z axis direction it is coping to same place(so there will be 2 objects in same place). If drawing line in Z axis direction it draws line with zero length. There is nothing to do with commands like ORTHO, OSNAPZ or "UCS position" as it doesn`t help.

Never seen this text beside crosshair before.

  

Move command...

Line command. Lines in X-Y plane are visible in z direction only zero length line.

Any ideas how to switch this "z-filter" off? 

Thanks in advance for any good solution...

perhaps you may get better feedback from one of these AutoCAD Architecture forums:

Thanks for attention. I found this place where z-Filter was on(it comes from extra plug-in).

Now problem is solved.
