How do I get the BOTH ends of a user-created sketch line segment?

dave_cowden

Suppose the user has created a sketch, and on that sketch has created a line segment. Further, assume I have this as an input to my feature :

        annotation { "Name" : "UserLine","Filter" : GeometryType.LINE,"MaxNumberOfPicks" : 1 }
        definition.userLine is Query;

Now, i'd like to access that linesegment from within featureScript.  I can't figure out how to do it.

I can get the sketch Plane on which the line resides:

var sketchPlane = evOwnerSketchPlane ( context, { entity: definition.userLine } ); 

..And I can get the line definition using evLine:

        var line = evLine(context, {
                "edge" : definition.userLine
        });

But this line definition only gives me the starting point of the line segment the user created, not the ending. But i need to get the beginning and ending of the user's line segment. How can I do that?

I have tried toString() to see if I can access properties of the object I get as a result of evaluateQuery, but that doesn't help me.

There do not appear to be any examples in std of getting a sketch entity this way.

Two ways to do this:
You can use evEdgeTangentLines  and pass [0,1] as the parameters argument (0 means start, 1 means end)
or:
you can use qVertexAdjacent(definition.userLine, EntityType.VERTEX) to query for the two endpoint vertices and then call evVertexPoint on each of them.

Oh yes of course, evEdgeTangentLines, did not think of that one!
Thanks for the fast answer!
