I am trying to model a composite section with parametric thickness and angle. As much as I have been able to figure out, when we define a layered section in Ansys Mechanical, then we can open a worksheet which includes the section definition and we must be able to see checkboxes that make the thickness and angle of each ply as parametric variables. The attached picture shows this option in the working space of Mechanical.

However, the problem is that I cannot find the checkboxes for parametrization of these variables and the properties of plies have to be changed manually inside the Mechanical (they are not accessible in the Parameters Set of the Workbench). My Question is whether the option shown in the picture is still available in V19.2 since it is quite convenient and helpful for the application that I have in mind. I will be grateful for any help in this regard.

Kind regards
