Grasshopper

algorithmic modeling for Rhino

I am using grasshopper for the first time (after watching tutorials).

 

I decided to practice on something that should not be that hard, a chess/checker board.

 

What I want to achieve is a generated chess/checker board with the following impute:

Length, with, number of squares in both directions.

 

Well I got it working as I want to although the code might not be the prettiest out there, I am still learning it after all.

 

The way its setup now the size of 1 square is defined by the size of the whole board (defined by the number of squares).

 

I want to know if it can work the other way around,

Can I by just imputing the size of 1 square (and the number of them) generate a chessboard (it does not have to be 8x8; I have to be able to set it)? This way the total size of the board shifts as I change the size of 1 square or the number of squares.

 

If any of you have pointers, tips then pleas do say so.

 

It’s not the intention that people make stuff for me, I chose this as a challenge to learn about grasshopper, so just give me pointers, and I’ll work it out myself. Thx in advance.

if possible the endresult should not have 2 sides of difrent squares on top of one other. so i cant just keep repeating making squeres, more like make 2 lines like a L shape. that would stop the squeres from geting on top of one and other, but than it would still need a border for the 2 sides i dident do.

H(o)i Mark,
check these examples, consider them as pointers, because I can't see how to continue from your file.

I don’t think it’s possible to continue from my file.

The new structure I want probably needs a new approaches

i see what you did. i also saw that as a possibility, but not one i wanted to take.

i just want lines, the inside of the squares don’t need to be coloured , actually i rather not.

 

might be helpful if i explain how i might be able to use something like this.

 

i want to use the (grid)lines, and engrave them into wood on a laze cutter/engraver.

for that propos i just need a grid in lines of a checkerboard / chessboard.

I have made a chessboard design in rhino before, but I wanted to know if I could automate a part of it.(seeing that a chess board is nothing but squeres).

I will ad in the chess bord that I drew by hand (took me a lot of time).

the main part beeing the red squeres (zoom in). in evry squere there is a other squere to make the lines thinker when lazer engraving them. (i know i could just adjust the with, but dooing it this way actuely saves machining time).

I might be using a part of the code you used tough, if I can manage to figure out what part.

I don’t want the squares to be a fixed size. I want to be able to adjust them with a slider. So it might not even become a square but rather a rectangle. also i dont need it as a survace, just the lines.

but thx a lot. i wil check outh how the code you send works, and how i can implement it(if possible).

You can attach a Curve Component to the surfaces to get their boundary curve. To get a thicker line I usually defocus the laser.

thx. ill check that out this weekend.

as for lazer work, defocusing laser wont give me a relaiable result, and as i am not using my own lazer but one of a makerspace, i try to not mess with it all that much.

a collegue of mine made a box maker for rhino (grasshopper).

you could just imput: length, with, thinkness of wood.

number of lips sticking outh (on both lenght and with).

and rhino would auto generate a whole box ready for lazer cutting. it saves me so mutch time.

size square x  n squares = total length.

i use lunchbox plugin: http://www.food4rhino.com/project/lunchbox

text tag need more work, but i hope you get the idea.

cheers.
