Usual Grid in Generative Components

Heiko Hornef
Offline
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

    Thinking about this for a while I would prefer using an Excel sheet for the definition of the grid distances.

    This allows different grid spacing (as frequently happening) on both axes without hassle.

    Hey Ingo,

    thank you for your help. 

    I think your model Looks very nice and I like the Connection to Excel, that you created. Can you tell me how I can connect the Excel Sheet to Model?

    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.

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

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

    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.....

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