The intersection worked quite well.

Here is my Transaction Log:

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

RE: Usual Grid in Generative Components

Ingo — Wed, 01 Aug 2018 15:14:52 GMT

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.....

RE: Usual Grid in Generative Components

Heiko Hornef — Wed, 01 Aug 2018 15:14:25 GMT

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

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

RE: Usual Grid in Generative Components

Ingo — Wed, 01 Aug 2018 15:11:30 GMT

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.

RE: Usual Grid in Generative Components

Heiko Hornef — Wed, 01 Aug 2018 15:10:53 GMT

i found the node:

Point.atIntersection...

But i have a Problem with the list. I want to have intersect first of list one with first item of list 2, second item of list 1 with second item of list 2, and so on...

Do you know how to do that?

RE: Usual Grid in Generative Components

Heiko Hornef — Wed, 01 Aug 2018 14:57:47 GMT

Hey Ingo,

thats very cool stuff, thanks for sharing.

I have only two more question about this.

1. Do you know how I can create Points on every Intersection of the Axis, so that I can put columns onto them. Is it possible to intersect geometries with a node?

2. How do i have to write the Code to get the first or the last item of a list? This Option would be great to have, if you consider to design walls on the outter lines of the Grid.

Thanks anyways for your Support. You helped me a lot so far.

Hey Heiko,

there's a node type for excel connection. And some hints in the help file.

Here's my script. You should be able to paste it into the transaction window.

transaction 1 modelChange 'Add baseCS, cs1, lineX'

and the excel sheet. I placed it just under C:/

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?

Heiko

RE: Usual Grid in Generative Components

Ingo — Wed, 01 Aug 2018 11:56:46 GMT

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.

RE: Usual Grid in Generative Components

Ingo — Wed, 01 Aug 2018 10:04:46 GMT

maybe something for a function (by Volker Mueller...)

otherwise I would do it about the same way. Maybe you could remove some nodes for widthTotal and lenghtTotal to slim it a bit down.
