ROTATER22.5(>00)
rotates, for example, the previously selected group 22.5° further around
the point (0 0). The > sign (right angle bracket) within the parenthesis
for coordinates causes the rotation of the whole group (as a right mouse

PackageswithRadialPadArrangement
It is possible to work with polar coordinates to place pads or SMDs in a
radial arrangement. Set a suitable reference point, for example, in the
center of the package with the MARK command first. The command

PackageEditor: RelativeandPolarCoordinatesDisplay
Values marked with an R are relative values referring to the previously
set reference point. The leading P indicates polar values referring to the
referencepoint.

Three pads are to be placed on the circumference of a circle with a radius
of50mm.Thecenterofthepartisatposition(00).
