[Connect] c# Display Rules - AreaPatternAction

Hi Salvatore,

[quote userid="1009364" url="~/products/programming/microstation_programming/f/microstation-programming---forum/197590/connect-c-display-rules---areapatternaction/588253"]This is the procedure I wrote to create the display rule[/quote]

I assume (but did not test it) that ElementId in AreaPatternParams should be element it of shared cell definition instance, which in the case of ThematicPlanStart.dgn is 1021.

With regards,

Jan

This is the procedure I wrote to create the display rule

 private void DiplayRulesSampleNew()
        {
            BIM.CadInputQueue keyInCommand = ustnApp.CadInputQueue;

            DgnFile dgnFile = BM.Session.Instance.GetActiveDgnFile();
            DgnModel dgnModel = BM.Session.Instance.GetActiveDgnModel();
            DgnModelRef dgnModelRef = BM.Session.Instance.GetActiveDgnModelRef();

            string RuleStenName = "RulSet_1";
            string value = "Attachment_1";
            string MyRuleCondition =  @"element.IsOfClass (""ShapeElement"",""DgnElementSchema"")";


            DisplayRuleSet displayRuleSet = new DisplayRuleSet(RuleStenName, dgnFile);
            
            DisplayRulesManager.WriteDisplayRuleSetToFile(displayRuleSet, dgnFile, true);
            DisplayRule displayRuleElement = new DisplayRule(MyRuleCondition, true, dgnFile);

            long elemId = 0;//1,2,3,4,5,6,7
            ElementId elementId = new ElementId(ref elemId);

            AreaPatternAction.AreaPatternParams patternParams = new AreaPatternAction.AreaPatternParams(
                elementId, 1, false, 45, 5, 1, 1);
            IDisplayRuleAction ruleAction = new AreaPatternAction(patternParams, dgnFile);
            

            displayRuleElement.AddAction(ruleAction);
            displayRuleSet.AddDisplayRule(displayRuleElement);
            DisplayRulesManager.WriteDisplayRuleSetToFile(displayRuleSet, dgnFile, true);

            keyInCommand.SendKeyin("MDL KEYIN CUSTOMDISPMODE DIALOG DISPLAYSTYLES");
            keyInCommand.SendKeyin(@"DISPLAYSTYLE CREATE ""DISPLAY_STYLE_BY_KEYIN""");
            keyInCommand.SendKeyin(@"MDL KEYIN VIEWCTRL CHANGE VIEW CUSTOM ""DISPLAY_STYLE_BY_KEYIN"" 1");
            keyInCommand.SendKeyin(@"DISPLAYSTYLE SETPARAM DISPLAYRULESET ""DISPLAY_STYLE_BY_KEYIN"" ""RulSet_1""");

            ustnApp.CommandState.StartDefaultCommand();


        }

Attached is the Dgn file and the cell library

thanks for the help,

And is it possible to provide example DGN file (just one or two elements + the rule)?

Creating the rule manually everything works.
The problem occurs when I try to code it through API

Hi Salvio,

it's not clear from your description whether the problem is "how to define action" (because it does not work even when created manually), or you have DGN file with working display rule, but there is a problem when the same rule should be created using API.

When DGN file with correct rule is available, it would be nice to share it. It's always better and more efficient than to describe it by words ;-)

With regards,

Jan
