unable to create hatch with odgeline2d loops
i'm having trouble writing hatches in certain cases. in particular, i can create a hatch with a loop containing odgecircarc2d's and odgeelliparc2d's, but not odgeline2d's.
i have made sure the four lines create a closed square by using the same odgepoint2d instance for the start and end points.
the following code results in -1 for figuretype in the dxf file, with no points, of course.
like i said, it works fine with circular arcs and elliptical arcs. this example code is pulled from dbfiller.addhatches(), which conveniently only users circles.
any pointers would be greatly appreciated. thanks!
edit: i'm using version 1.13.
code:
oddbhatchptr phatch = oddbhatch::createobject();
oddbobjectid solidhatchid = pblock->appendoddbentity(phatch);
phatch->setassociative(false);
phatch->setpattern(oddbhatch::kpredefined, "solid");
phatch->sethatchstyle(oddbhatch::knormal);
odgepoint2d llpoint(3.0,3.0);
odgepoint2d lrpoint(10.0,3.0);
odgepoint2d ulpoint(3.0,10.0);
odgepoint2d urpoint(10.0,10.0);
edgearray edgearray;
edgearray.push_back (new odgeline2d (llpoint,lrpoint));
edgearray.push_back (new odgeline2d (lrpoint,urpoint));
edgearray.push_back (new odgeline2d (urpoint,ulpoint));
edgearray.push_back (new odgeline2d (ulpoint,llpoint));
phatch->appendloop (oddbhatch::kdefault, edgearray);

odgeline2d is infinite line.
use odgelineseg2d.

thank you. that hadn't occurred to me.
