SrfGrid wont activate from meshray, Trying to create srf from contours with bounding box

001_landskap-grasshopper.gh (160.0 KB)

Have used this script before, but suddenly the SrfGrid wont react, have tried different bounding boxes (Larger than contours, smaller etc.) Seems like I have missed something obvious but i cant find out what.

Cant upload rhino file on here so link to drive with file;https://drive.google.com/file/d/1zccLnnp2ngQuSog5h92AMs-5OV0vewnq/view?usp=sharing

Hope someone can help.
Best, Siri

I made three changes:

  1. Used the bottom face of a Bounding Box around the mesh.
  2. Used Pick’n’Choose to replace nulls with base points.
  3. Replaced SrfGrid because the ‘I’ input was not initialized, causing the “1. Input parameter I failed to collect data” error.

Thank you so much, I would never had figured that out! :pray: :slightly_smiling_face:

Hello again. Now I have the same problem as I had earlier - what is the mistake im doing?
The problem is that ‘‘a point in the grid is null. Fitting operation aborted’’, But the boundary box is lower than the contours.
