Rotate point symbol based on a field

AquanuityDevelopment

I just could not make this attribute driven symbology feature to work using ArcGIS Pro SDK.  The following is a snippet of my code:

var render = lyr.CreateRenderer(simpleRender) as CIMSimpleRenderer;

var cimExpressionInfoZ = new CIMExpressionInfo { ReturnType=ExpressionReturnType.Numeric, Expression = "$feature.Direction" };
var cimVisualVariableInfoZ = new CIMVisualVariableInfo { VisualVariableInfoType = VisualVariableInfoType.Expression, ValueExpressionInfo = cimExpressionInfoZ};

var listCIMVisualVariables = new List<CIMVisualVariable>
{
new CIMRotationVisualVariable {
VisualVariableInfoZ = cimVisualVariableInfoZ,
RotationTypeZ=SymbolRotationType.Arithmetic
}
};

render.VisualVariables = listCIMVisualVariables.ToArray();

lyr.SetRenderer(render);

 

I would like to rotate the symbol based on a field called "Direction" with angles range 0 - 360.  The symbols have been rotated but not according to the values in "Direction" fields.  Any help will be great appreciated.

Hi,

Try code below. It works for me.

        protected override async void OnClick()
        {
            var featLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().First();
            await QueuedTask.Run(() =>
            {
                var render = featLayer.GetRenderer() as CIMSimpleRenderer;
                var cimVisualVariableInfoXY = new CIMVisualVariableInfo
                {
                    RandomMax = 360,
                    RandomMin = 0,
                    VisualVariableInfoType = VisualVariableInfoType.None
                };
                var cimExpressionInfoZ = new CIMExpressionInfo
                {
                    Title = "Custom",
                    ReturnType = ExpressionReturnType.Default,
                    Expression = "$feature.Direction"
                };
                var cimVisualVariableInfoZ = new CIMVisualVariableInfo
                {
                    RandomMax = 360,
                    RandomMin = 0,
                    VisualVariableInfoType = VisualVariableInfoType.Expression,
                    ValueExpressionInfo = cimExpressionInfoZ
                };
                var listCIMVisualVariables = new List<CIMVisualVariable>
                {
                    new CIMRotationVisualVariable {
                        VisualVariableInfoX = cimVisualVariableInfoXY,
                        VisualVariableInfoY = cimVisualVariableInfoXY,
                        VisualVariableInfoZ = cimVisualVariableInfoZ,
                        RotationTypeZ=SymbolRotationType.Arithmetic,
                        NormalToSurface = false
                    }
                };
                render.VisualVariables = listCIMVisualVariables.ToArray();
                featLayer.SetRenderer(render);
            });
        }
