How to connect two meshes with columns?

Hello everybody,

i would like to connect two meshes with a kind of column like here -> Connection

The meshes i want to connect look like here (the original source you can download below):

As you can see on the Picture, i marked two points from the Mesh with a circle. But there are more columns expected than one!

Thx for help :)

Hey guys,

nobody any idea how it could work? Maybe someone had the same problem in the past and can tell me some keywords...

That would be perfect!

Thx

Lena

Hi Lena,

that's a pretty big file you uploaded that does a lot of things. Are they all necessary for your column problem? If not, can you upload a file that has the minimum amount of stuff in it?

Or, alternatively, can you tell us the logic behind these columns you're after? Are they lines or are they those flowing sort of shapes from the link you provided? Which points on mesh A should connect to which points on mesh B?

Hi David,

thank you for respond to my question :)

I'm trying to explain the logic behind these columns (sry for my english)...

As you can see in the ".txt" file, these points of the meshes should be connected with a column. Each corner of mesh A has got a partner on mesh B. The numbering is given in the ".gh" file - i made it visible.

The form of the column has to be hollow, so that you can look through. It would be fine, if the column and the mesh grow together and are perceived as one object. Maybe that means, that the column has to be also triangulate?!

Relating to the shape of the column i would like to have a flowing shape, adjust by a slider...

And when all this is made in grasshopper, i'm going to perforate the meshes to make them look lighter. In the end it will be printed as a 3d model. Hopefully!

Each corner of mesh A has got a partner on mesh B.

I don't get it. One mesh has 24 points, the other 26. How can they be paired up?

Yes that's true, but it's right in terms of my intention. All the stuff i made in gh is based on an analysis of a board game called "rosenkönig". The aim is to make the course of the game and the rules visible in a 3d structure. The two more points from player B (Mesh B) are justified with the "end of the game of player A". He couldn't do anything more in the game, so there is no connection between the meshes.

I correct myself: "Nearly each corner has got a partner"....

Is it now a little bit better to understand?

Ok, so Vertex 1 in Mesh A is connected with Vertex 1 in Mesh B. then Vertex 2 in Mesh A is connected with Vertex 2 in Mesh B and so on, until Mesh A runs out of vertices. The two superfluous vertices on Mesh B remain unconnected.

Have I got that right?

If I just connect the points in order then the above is the result. Is that correct?

It looks pretty good!

But i'm not sure if the order is right. (-> csv file)

Point 23 (A) connected to Point 11 (B)

21 (A) to 9 (B)

19 (A) to 18 (B)

27 (A) to 36 (B)

...

and so on!

But I think that the result would be similar to your way of connection (1-1 / 2-2 / 3-3 / 4-4 / ...)

Oh yeah I forgot about the csv file. It'll be easier if the CSV file doesn't contain any data other than the numbers. I removed the first two lines in the csv file and also the empty last line.

Actually it's a bit neater with [List Item] instead of [Flip Matrix] and [Explode].

Wonderful!

Meanwhile i've tried something for the columns as you can see in the picture. I don't know whats wrong with the top of the column, but the way of building it is perhaps useful.
