Hi,

I am trying to create a hollow sphere. For this I was trying to use the dynamic modeler tools option of ‘hollow’. I had expected that it would create a shell of the specified thickness. Instead it creates another model which just gets shifted by the specified thickness. I have attached the screenshot. Incase there is another option for creating a hollow sphere, please let me know.

Thanks

I found the problem. It was an ordering error. I need to first make a hollow and then a plane cut.
