plot preview question
plot preview question
hi,
i wrote some simple code to draw a line in file. i can see it in file as well as i can plot it. however i can't see it in plot preview. the code is like:
oddbblocktablerecordptr pblock = modelspaceid.safeopenobject(oddb::kforwrite);
//add line and set the attributes
oddblineptr pline;
pline = oddbline::createobject();
entid = pblock->appendoddbentity(pline);
pline->setstartpoint(start);
pline->setendpoint(end);
pline->setcolor(forecolor);
pline->setlayer(player);
anyone knows the reason?
thanks,
al
i found the reason, that is because of the color set for the entity.
