** Severe ** CheckConvexity: Surface=“Zone_0_SRF_1” is non-planar

Dear All,
Could you help me with this error?
The simulation has not run correctly because of this severe error:
** Severe ** Check Convexity: Surface=“Zone_0_SRF_1” is non-planar.
Knowing that I used the same file from Chris Mackey course.

Seems to be difficult to say without a file.
Seems that the component expects a planar surface. Just guessing

I really recommend just using the LBT 1.3 plugin. These types of errors have been practically eradicated over there.

I updated my tools to 1.3 put still the same error

could you check it please

No, it’s still legacy. Remember that the LBT components are completely separate from the Legacy ones and, if you are using the latest version, the Legacy and LBT components are in separate Grasshopper tabs.

Hi
I have a similar problem. I am working with the latest LBT 1.4.0.
The gh file is attached with this comment. Can you tell me what I am doing wrong?

Your script is running fine on my end. I only removed the cooling and heating limit as zone temp error was popping up. I also recommend you checking compatibility matrix to know about version of Open-studio supported with LBT 1.4.

Thanks updating the open-studio and removing the limits worked.

Hi
I am having a similar error again. For the same file. This time my rhino version is 7.20 (latest) and open-studio I upgraded to 3.4.0.

Hi,
I am attaching the grasshopper file. Kindly suggest what to do?

I’m not able to recreate the issue in LBT 1.5.

So I suggest that you update your plugin.
