Removing Mesh Control

Hi all

Does anyone know how to remove a mesh control?
I tested a mesh optimization tool and I end up with almost 1000 mesh controls and I can't delete them.

Thanks in advance

Hello @stephane.yvart_1

Can you specify if this mesh optimization tool is indeed an internal SW tool.

Kind regards

PS: Which version of Sw??

Hello

Normally you click on the control in question in the tree and you do "delete".
