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
regards,

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.
