The Set SMD Attribute action is a read/write DFM action that attaches the .smd system attribute to a subset of the pads in a layer. The purpose of this action is to prepare the layer for effective analysis that will be able to separate measurements into different categories according to types of pads. Setting of the attribute is based on the shape of the pads and whether pads are drilled.
Reports the total number of modified pads as well as a histogram by the names of the pads.
For example, lyr1_set_smd , lyr2_set_smd, each provides a total for a specific layer (lyr1, lyr2), while set_smd provides a total for all layers.
