Shapes
A rounding factor can be specified here for SMD pads. The value can be
between0%(norounding)and100%(maximumrounding).
Roundness:0-10-25-50-100[%].Right:100%,square
A square SMD has been placed instead of an oblong one on the far right
of the diagram. After assigning the property Roundness = 100%, the
SMDbecomesround.
This is where the form of the pads is specified. It is possible to give dif

ferent settings for the top and bottom layers. The As in library option
adopts the form defined in the package editor. Clicking on Apply shows

If pads or vias have different shapes on different layers, the shapes of the
currently visible (activated with DISPLAY) signal layers are displayed
ontopofeachother.
If the color selected for layer 17, Pads, or 18, Vias, is 0 (which represents
the current background color black or white), the pads and vias are dis
