Usual Grid in Generative Components

Hello everybody,

I'm trying to create a simple axis grid. It should consist of X-directed and Y-directed axis lines and you should be able to set the number of axes and the distances between them by number-sliders.
My first thought was:

1. lines on the X and Y axis
2. points on these lines to determine distances and number of axes (e.g. length 10 m, number of points 5 --> points every 2 m)
3. axis grid lines: Starting points are the points on the axes (X direction, if point on Y axis and vice versa)

It seems quite complicated to me and I can imagine that there is an easier way. Does anyone know?

Best regards, Heiko

The intersection worked quite well.

might get a bit tricky if you have unequal grid numbers......

ok you were quicker. ;-)

Maybe just toggle off replication / or delete in the code.

But this might cause unwanted results when you have uneqal grid numbers.....

again i found the answer. I should stop asking before really trying

It was a subject of replication style of the lists, of course

for the intersection - that's quite straightforward:

transaction 5 modelChange 'Add point3'
{
    node User.Objects.point3 Bentley.GC.NodeTypes.Point
    {
        Technique                 = 'AtIntersection';
        Intersector0              = gridX;
        Intersector1              = gridY;
        GraphLocation             = <auto> {1410.0, 40.0};
        Replication               = ReplicationOption.AllCombinations;
    }
}

The rest I don't quite get - the last point of a list is point1[x] with x equal the highest instance.

Or point1[0] for the first. Maybe that helps.
