I am a bit of a newbie, but I've always found that when you move an object in Chief, it moves until it hits something (such as an adjacent cabinet) and then stops. If the adjacent cabinet is able to move, then the entire block will move if you push it hard enough with the mouse, but objects won't overlap and occupy the same space.
Now this functionality seems to have disappeared. If try to push a kitchen cabinet against another cabinet it keeps on going, right into space that the other cabinet occupies. Same with walls, etc.
Is there a toggle i am not aware of to change this behavior? I am going nuts! I need items to snap to each other, and not just melt into each other! thank you!!
