edge query to map

nathan_shaffer

How do I get all of the lines for edges in a query?

evLine wants an edge, how do I unpack the query to feed into evLine?

annotation {"Name": "Edges","Filter" : EntityType.EDGE, "MaxNumberOfPicks" : 2 }
definition.edges is Query;

var lines = evLine(context, qEntityFilter (definition.edges, EntityType.EDGE));

You need to evaluate the query to make it into an array of queries with one edge each, then loop over the array and evLine each one. Here's an example.

    // Gets the edges of the selected face
    const edgesOfFace = qLoopEdges(definition.face);
    
    // Makes the one big query into an array of individual queries for just one edge each
    const edgesAsArray = evaluateQuery(context, edgesOfFace);
    
    // make an empty array to collect the lines from the loop
    var linesArray = [];
    
    // iterate over each edge
    for (var edge in edgesAsArray)
    {
        try
        {
            // evLine on only one entity
            const edgeLine = evLine(context, {
                    "edge" : edge
            });
            
            // Display the line and print it's contents to the FS notices panel
            debug(context, edgeLine, DebugColor.RED);
            
            // add this line to the array, so we have them all together once the loop is done.
            linesArray = append(linesArray, edgeLine);
        }
        // if the edge isn't a straight line, evLine fails and we run the catch statement.
        catch (error)
        {
            reportFeatureInfo(context, id, "Non-line edges ignored.");
        }
    }
