Unexpected behavior of EAGLE layout editor

Simply placing this gate on schematic causes significant changes on the board. As you can see, multiple nets become ripped up, even the nets that have nothing to do with IC5 or IC9.

 

Is it possible to avoid this effect?

Hi Sergey

It's important to say which version of Eagle you are using.

I use v7.7 (Win7)  and can demonstrate I don't have  your problem.

Using the example Schem/Board Hexapod I can copy a device in the

schematic and it appears without air-wires on the board, ready to be

placed. The rest of the board remains unaltered.

It may be the technique you are using to copy the part (ah! maybe the v8

select mechanism has caught you out). I simply right click on the symbol

(IC5) and select copy from the context menu. Then you will only have the

IC stuck to the cursor and no nets connected to the pins.
