problem with extrude function
problem with extrude function
hello!
i'm trying to create a solid 3d and i'm using extrude function. but if i call createfromcurves function then function return enointerface result. this is my code:
oddb3dsolidptr p3dsolid;
oddbcircleptr circle;
odrxobjectptrarray curvesegments;
odrxobjectptrarray regions;
odresult result;
p3dsolid = oddb3dsolid::createobject();
p3dsolid->setdatabasedefaults(database);
database->appendoddbentity(p3dsolid);
circle = oddbcircle::createobject();
circle->setdatabasedefaults(base_de_datos);
circle->setcenter(odgepoint3d(x, y, z));
circle->setradius(radius);
curvesegments.push_back((odrxobjectptr)circle.get( ));
result = oddbregion::createfromcurves(curvesegments, regions);
// here result is enointerface.
p3dsolid->extrude((oddbregionptr)regions[0], longitud);
these are the libraries linked.

what's my problem?
thank you.
you should load modelergeometry.drx too.
