AutoCAD knows nothing about private members of
your custom object's class, so the worldDraw() of
those instances will not be called. You would have
to do it explicitly the worldDraw() of the containing
database-resident entity.
AFAIK, there's no hatch() function that draws hatching
geometry, so you would either have to calculate the
hatch geometry yourself, or create and use a hatch
entity in your worldDraw().

Hi
I have a few questions regarding worldDraw():
1. please consider:
class A : public AcDbEntity { };//custom class
class B : public AcDbEntity { };//custom class
class C : public AcDbEntity {
A a;
B b;
public: double f;
}
Does acad call a.worldDraw() or does C::worldDraw() have to (optionally) do
it? The same question for dwgIn/OutFields().
Does b.worldDraw() have access to f?
2. To display a hatch inside a.worldDraw(), is there a hatch() function
callable from there, or do I have to embed an AcDbHatch object inside my
custom object?
Thanks
alex
