MATCH AND REPLACE

Hi Everyone,

I am a beginner to grasshopper I would like some help with a fast way with 2 task in matching and replacing points with corresponding values.

1) List 2 (Bottom list) is a series of points. I would like to rename them such that they are named R1....Ri while corresponding to each points

2) the points in each branch in List 1(Top list) are the 3 vertex defining each triangle surfaces. I would like to match every point in list 1 with list 2 and replace the index in list 1 with the corresponding Ri defined in step one

Thus hoping for a final output list for example like

{0;0}

1. R3

2. R28

3. R90

{0,1}

1. R92

2. R93

3. R20

...and so on

Thank you for helping

Hallo Mark,

In the screenshot below, I have provided two possible ways in which you can achieve your goal. Each option has its own merits and demerits.

For instance, option 1 matches the points based on the co-ordinates, which means that unless list 1 is made up of the exact same points in List 2 (to the last decimal), the text-match will not work.

In option 2, the matching of points is done by finding the closest point from List 2 to each of the points in List 1.

Depending on what your situation is, I hope one of these methods will suit your needs.

Cheers,

Sridevi
