Re: Change Elements Elevation with in the drawn polygon and break lines (Microstation V8i Using MDL Language or C#.Net)

mdlLinear_extract(PolyElmVer,&PolyElmNoVer,&PolyMsElm,MASTERFILE);

if(SUCCESS == mdlMeasure_polygonProperties(NULL,NULL,(DPoint3d*)&plane_normal,&plane_origin,NULL,NULL,NULL,NULL,PolyElmVer,PolyElmNoVer))

I did any mistake ?
