5. CAD Drawings

2D drawings can be represented using CADD (Computer Aided Design Document) objects. There are currently 3 ways of creating CAD documents in OpenBrIM.

1. CADD object represents a blank 2D drawing document. Each CADD object could contain CADD object's child elements (ex. CADDLine, CADDEllipse etc.) representing the drawing in the document.

2. CADDFrom3D object allows automatic 2D drawing generation from 3D objects.

3. CADDFromDoc object creates a 2D drawing from a document. This currently supports PDF documents only.
