Grasshopper

algorithmic modeling for Rhino

Hello,  i am new to Grasshopper .

I am trying to build surfaces from the text file (points.txt) .

If there is way to divide the file list with "empty" and import separately to polyline and boundary surfaces?

 

Thank you for any advice!

Hi Tommy,

You should split your original list of points into sub-lists according to different domains that are defined by the empty items ..

I hope this helps

Hi Ibrahim,

Thanks for the advice. I tried to build the domain, but i don't know how to write the vb script to find the empty row. Can you show me how?

Thank you!

Hello Tommy, Ibrahim,

Is this relevant to your problem?

This is a simple equality test, if nothing is pluged in y this means that the data is empty so the VB will compare the empty with another empty and will give you a "true".

Yes Nikos, your previous post is relevant as well and could be another way with less components) but the "null component" doesn't work with <empty>, that's why I used the simple VB script to catch the <empty>

Many thanks for the clear method.

It works very well:)

Here's a trick using only string operations. I do think your textfile is borked, it seems to have a line break in the middle of one of the points.

I tried your method, however cleaning tree is not working for some reason I am not sure why ..

Cheers Davis, that's a fantastic way .. Thanks for sharing ..

I think it is not working because clean tree removes <null> items not <empty> items right ?

you are probably right.

On the same topic, ng5 Alex provided a solution that works with <empty>, have you checked this one out?

Alright, I missed this one, it is working very well, he translated the <empty> to <null> and then followed your way ..

Cheers Nikos

Hi nikos tzar

I tried the ng5 Alex's solution,but i didn't find the component called "Len"

Where can i find it? thanks. 

I believe it's TextLength.
