the pet palette is, for me, one of the best things about ac
select an element on the floor plan. now 'press' the mouse button on a node or an edge. the pet palette will appear. and follow your cursor around
the pet palette gives you tools for manipulating or modifying the element (the last icon on the palette usually switches between these modes)
the content of the pet palette usually varies depending on whether you press on a node or an edge
experiment. it's essential for efficient working in ac (and some commands, like roof edge angle, are only available here)
