hi,
i've noticed that in odgigeometrysimplifierlylineproc number of points passed are always 2, even if oddbpolyline has more than 2 points. simply, subsequent line segmets of polyline are passed to polylineproc separately, in order as they are in polyline. is it an invariant? can i assume that it is also true for oddb3dpolyline, oddb2dpolyline? will it be invariant in future releases of library?

no, it isn't invariant. primitives, that you're getting through odgiconveyorgeometry interface, depends on composition of the rendering pipeline. primitives that are returned from pipeline for particular entity can change in future releases.
sincerely yours,

so when i am in polylineproc, i don't know whih points on current polyline match given screen-points.
now i check if last call to polylineproc was with the same entity, and if so, i use the number of last passed screen-points to figure out matching.
by the way, is there possibility in polylineproc to get wcs coordinates of entities? currently i get only 'local' coords (eg. in block or view(modelspace))
