ROD objects or pcRects in pcells?

[grivdev]

Could anybody explain what is the difference between creating rectangles of a specific layer in a pcell with dbCreateRectangle and rodCreateRect?

Thank you in advance.

db objects (created with dbCreateRect() are the low level database
objects). ROD objects are a higher level construct; for example, a ROD
object can contain multiple parts (so you can have multi-part paths or
multi-part rectangles). Underneath they have DB objects to represent the
actual shapes, but they also maintain a higher level object to allow you
to locate the shape by name, perform alignment, use convenient handles
to access points on the shape, and so on.
