OdDbHatch Class

Class Hierarchy

Syntax

C++

class OdDbHatch : public OdDbEntity;

File

DbHatch.h

Description

This class represents Hatch entities in an OdDbDatabase instance.

Remarks

Loops must be closed, simple, and continuous. They must be self-intersecting itself only at their endpoints. Their start points and end points must coincide. The outer loops must be appended before all of their inner loops.

The Drawings provides limited validation of the hatch boundary in order to maintain API efficiency and performance.
