Assistance getting text file to model definition working properly

Hi all,

New to grasshopper and I’m working with a definition I got online to transform a text file to a 3d model. I followed the tutorial exactly and ran across this error on the first component that reads the text file.


  1. Line 37: Function ‘ParseLine’ doesn’t return a value on all code paths. A null reference exception could occur at run time when the result is used.

Online it seems to work for most people. Could it be an issue with my version of rhino and/or grasshopper?

Any help is greatly appreciated.



Post your text file…

Sorry I didn’t realise I should do that.

I in fact solved it, it was a bug to do with the file path component.

All i had to do was delete the file path component, and then create a new one and it would work…
