Turning off history capture prevents code execution

[lachycharts]

A small snippet of my code is below which creates a shell and then a tangent plane on it's outer edge. The code then undergoes a lot of iterations and so I would like to turn history capture off to improve performence, however when I disable history capture, a plane through the centre of the extrusion occurs. Why does history capture affect execution of the code?

Thanks

Hello,

Thank you for reporting the issue to us. It could be a bug of ConstrnctionPlane API. I logged UP-28626 to track it. We will investigate and fix it in future updates.

Thanks,
