Multipart Paths

---

You can use the Create Multipart Path command to create named paths that have relative object design (ROD) information associated with them. You can create simple one-part paths or complex paths containing several parts, such as a guard ring, transistor, bus, or shielded path. A path that consists of more than one part is called a multipart path (MPP).

A multipart path consists of a single master path and one or more subparts. The master path is the defining object; all subparts are based upon and exist in relation to the master path. You can define any number of subparts for a multipart path. Subparts can be any or all of the following: offset sub-paths, enclosure sub-paths, and sets of sub-rectangles. Also, you can define connectivity for any or all parts of a multipart path. In the layout editor, a multipart path (master path and all its subparts) is treated as a single object.

A ROD multipart path offers advantages over a regular path. For example, you can access a ROD multipart path by name, even through levels of hierarchy, and you can chop it.
