odgiextcalc
hi,
is there any way do ignore some kind of entities while computing extents using odgiextcalc? i've tried to override dodraw but it's not called. cextentscalc derives from odgiextcalc.
code:
odrxobjectimpl<cextentscalc> extcalc;
extcalc.setcontext(pdwgcontext);
extcalc.draw(pspace);
extcalc.getextents(extents);
tia

this is implementation of odgiextcalc::draw
code:
void odgiextcalc::draw(const odgidrawable* pdrawable)
{
m_bboxset = false;
pdrawable->setattributes(this);
pdrawable->worlddraw(this);
m_bboxset = false;
}
it call worlddraw. worlddraw will call ::draw() inside and ....
so it seems that you should add check inside void odgiextcalc::draw(const odgidrawable* pdrawable), not inside dodraw.
