Hi, do you think is there maybe method use the Snap to objects button to snap certain shape to Grid?

According to the attached picture, I did the following

1) switching on the Show grid in Windows menu, with this a small + signs appeared
2) drew a green triangle, and would like if the top of it would be exactly at one of the + sign

Maybe such exact snap could be only applying a vertical and horizontal Guide line with switching on the Rulers?

thanks,
