Yes, you can use a Tube symbol in Dynamic mode. Here is some code to get you on the right track: GraphicsOverlay* overlay = new GraphicsOverlay(this); overlay->setRenderingMode(GraphicsRenderingMode::Dynamic); auto sceneProps = overlay->sceneProperties(); sceneProps.setSurfacePlacement(SurfacePlacement::Absolute); overlay->setSceneProperties(sceneProps); m_sceneView->graphicsOverlays()->append(overlay); PolylineBuilder* pb = new PolylineBuilder(SpatialReference::wgs84(), this); pb->addPoint(0,0,0); pb->addPoint(1,1,20000); pb->addPoint(1.5,1.5,10000); pb->addPoint(1.75,1.75,0); SolidStrokeSymbolLayer* strokeSymbolLayer = new SolidStrokeSymbolLayer(5000, QColor("red"), {}, StrokeSymbolLayerLineStyle3D::Tube); MultilayerPolylineSymbol* tubeSymbol = new MultilayerPolylineSymbol({strokeSymbolLayer}, this); Graphic* graphic = new Graphic(this); graphic->setGeometry(pb->toGeometry()); graphic->setSymbol(tubeSymbol); overlay->graphics()->append(graphic);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
