Component shapes and types in PADS.
PADS has a section DECAL and PARTTYPE.
DECAL is the physical, graphic description of a shape (i.e. DIP14).
PARTTYPE is a defintion of components which used one or more decals (alternates). The PARTTYPE is what places the component. A PARTTYPE also can change pinnames of a DECAL.
CAMCAD does the following:
DECAL : All DECALS are converted to Geometries.
PARTTYPES : are attached as a ATT_TYPE to a component.
If a PARTTYPE has alphapins, a new GEOMETRY (DECAL) gets created called TYPE_DECAL and the component gets this Geometry attached.
The CAMCAD Typelist must have a unique identification between component and its defintion. PADS can change a PARTTYPE with alternate Decals.
Layernames:
Pads has layer numbers and layer classes. CAMCAD assigns the following names to these classes:
PADS Layer numbers used in DECAL section are called DECAL_nr
