ArcGIS Desktop 10.3 follows following cad data model on direct read of a CAD file. Following lines I have copied from ArcGIS Desktop 10.5 help.
All CAD feature datasets display a standard set of five feature classes, one for each supported shape type. These feature classes display aggregate collections of geometry contained in the source CAD drawing.
Hi @Madanbhurati1,
Starting in ArcGIS Pro 3.2 (released in Nov. 2023), read-only feature layers from CAD are created and organized so that the number of layers is reduced and performance is improved.
As additional detail:
By default, the CAD entities are now organized into one group of group layers. Within that highest-level group, the CAD file entities are organized by geometric type into Annotation, Point, Polyline, Polygon, and Multipatch.
