AcDbPolyline vs AcDbRegion in custom entity.

[Anonymous]

I designed a custom entity which has an AcDbEntity* member. If I set the color on my custom entity, the member entity is drawn in that color if it is a polyline, but if it is a region, the color stays on "by-layer". Does this make sense? Why the difference?

Adesk::Boolean Element::subWorldDraw(AcGiWorldDraw* dc)

{

     AcGiDrawable* drawable = static_cast<AcGiDrawable*>(_primitive);

  if(drawable)

    {

        dc->geometry().pushModelTransform(Translation());

        drawable->worldDraw(dc);

        dc->geometry().popModelTransform();

     }

   return Adesk::kTrue;

}

It sounds like the region sets a color before drawing, and the polyline does not. This is not unusual, as there is no rule about whether an entity must or can set a color before drawing. Presumably you can set the region's color so that it draws whatever color you want.

Hi,
Have you overriden AcDbEntity::subSetAttributes method (calling embedded _primitive->setAttributes(pTraits) )?

I did, and it didn't seem to make any difference. I could override setColorIndex(...) I guess...
