How get all entities of the SW drawing

what do you mean by entities? there is no get all entities in a drawing. if you mean View::GetLines4, View::GetFirstNote, View::GetFirstWeldSymbol, View::GetFirstAnnotation2, View::GetDimensionDisplayInfo4, View::GetDimensionString3, View::GetSketch then thats different.

View::GetPolylines returns the actual view (projected, cut...) geometry. The result requires some processing to be usable. Then, using View::GetViewXform, you might be able to find the corresponding 3D Edges, but it is hard...

Ok, Sean Phillips I got it. I understand that there no function to get all entities, and I have use different functions to do it. Thank You Felix
