Use the Edit > Reshape > Offset command to offset all edges of an existing element. This function works on:
•all elements that are polygonal (these include splines as well as the more obvious polygon-type elements)
•multiple connecting elements of a single type, provided they are all selected: for example, two line segments that meet at a point
