Thanks Kevin! I did like you said. I thought that LDD self-adjusting the rotation. Where could I get to know this type of tricks? Is there any source ?

I can not put together (it means engaging in) the two gears with eight teeth - LDD program prevents me from putting these gears next to each other, and I do not know why? Can someone please help me solve this problem? I am a new user of Lego Digital Designer and I do not know what wrog I do while trying to engaging in of these wheels. Very please to grant me help.
