I want to make tensile structure. So, I’m trying to imitate this video. ([How to make 4 basic tensile structures! - Rhino/GH Tutorial - YouTube](https://www.youtube.com/watch?v=I-pa9MhGzdw))

But my grasshopper doesn’t work when I use Naked Vertices. it says “Solution exception: Object reference not set to an instance of an object.” The other is fine.

How can I solve this situation…? pls… I should solve this problem immediately.

You might want to upload your .gh file (with referenced Rhino geometry internalized) and post the outcome of the Rhino `SystemInfo` command.

Thanks for reply. Did I upload the correct file that you said?

Hi -  
Thanks for those files.

The problem starts upstream from that component:

![image](https://global.discourse-cdn.com/mcneel/uploads/default/original/4X/6/c/5/6c5c0ecea1dd2476e374ae04996bf7e776528248.png)

When you hover over the `U Count` or `V Count` inputs of the Mesh Surface component, you’ll see that it asks for an integer. You are providing a double that is smaller than 1.

You’ll get away with providing a double because the component will automatically round it to the nearest integer but you can’t have U and V counts that are smaller than 1.

Please make sure to update to the current Service Release or Service Release Candidate.
