I created components, add pins to them and connect by wires. But wires are shown as straight lines, from pin, to pin.
How I can get bended wires ? Should I add a specific properties to pins, for assigning wire directions ?
If you want to gives the wires a "real" feel to them in your rendering then just make them bend a little when you make them in Inventor. While doing so ensure that they starting point and ending point end where they should. In order to get bent wires use the sweep command and use a curve driven pattern.
