width

The width of the symbol. When getting the width from a multilayer polyline symbol, the value reported is the largest width of all the symbol layers it contains. The symbol width is updated when its symbol layer widths change (if there is a new largest layer width). When setting a new width at the polyline symbol level, the width of the largest symbol layer is given the provided value, and all the smaller layers are sized proportionately. An individual symbol layer can be given a specific width without affecting the other layers.

The measurement unit for the width is in device-independent pixels (DIPs) by default. To use meters in 3D scenes, set the MultilayerSymbol.sceneSizeUnit property to SymbolSizeUnits.Meters. This switches the interpretation of the width from DIPs to meters.
