setting geometric extents for oddbpolyline
setting geometric extents for oddbpolyline
how do we set geometric extents for a newly created oddbpolyline?

you can't set the extents. you can append/insert vertices or edit existing ones.

geometric extents in polyline
thans for the reply...
but...after inserting the verticies when i do below steps, the last line fails and i get an unhandled exception.
oddbentity* pent = ppolyline.get();
odgeextents3d pt;
pent->getgeomextents(pt);
-praveen
need more clarification
i'm trying to do below:
polyline_ = oddbpolyline::createobject();
polyline_->addvertexat(0,odgepoint2d(-250.0, -100.0));
polyline_->addvertexat(1,odgepoint2d(-250.0, -200.0));
polyline_->addvertexat(2,odgepoint2d(-150.0, -200.0));
polyline_->addvertexat(3,odgepoint2d(-150.0, -100.0));
odgeextents3d extents;
polyline_->getgeomextents(extents)
doing above is causing an unhandled exception in last line.
am i doing something wrong?
some operations may fail if entity's database is unknown.
if you call polyline_->setdatabasedefaults(pdb) the polyline will "know" its database and getgeomextents() will work.
btw, setdatabasedefaults() only initializes some entity properties without adding the entity to database.
