Cut Point 3D Point Evaluation

Hi there

I am trying to obtain data for a point on my model that is not directly defined within the geometry. I have used the "Cut Point 3D" to add a point on my model, then I was going to use the "Point Evaluation" option to find the data at this point.

However, after defining the 3D point, and plotting it on my geometry, I am unable to select it in the point evaluation option. How do I ensure that the point has been created?

Thanks for your help!
