i have my own object deried from entity

it is normally displayed - everithing Ok

when autocad is calling saveAs(), i instead of normal calling of worlddraw func. call my own function to participate subEntities

there is the problem:

when geometry()-> calls polyline() i call AcgiLineTypeEngine::tesselate() to participate polyline of different linetype

when i open file without arx initialisation, the proxy entity will appear

BUT when i explode this one (polyline as proxy in my case), the exploded object should be the same, but it's not. It has set the "linetype generation" in propertiesBox to off, when i change this flag manually - it's ok

how can i change this flag to true during saving proxy gaphics?

i tried AcdbDatabase::setPlinegen() but doesn't affect

so - proxy drawn by tesselation is ok, but the exploded proxy object has changed the plinegen flag to false (this flag means overflowing of non_continuous linetype over vertexes)

would you help me pls?

thank you very much
