cadnano.part.part module¶

class Part(*args, **kwargs)¶

Bases: cadnano.cnobject.CNObject

A Part is a group of VirtualHelix items that are on the same lattice. Parts are the model component that most directly corresponds to a DNA origami design.

Parts are always parented to the document. Parts know about their oligos, and the internal geometry of a part Copying a part recursively copies all elements in a part: StrandSets, Strands, etc

PartInstances are parented to either the document or an assembly PartInstances know global position of the part Copying a PartInstance only creates a new PartInstance with the same Part(), with a mutable parent and position field.
