I am having trouble creating an axisymmetric rectangle. I am trying to model micro indentation of a steel flat cylinder rigid object to a 15x15x10 mm^3 PDMS. But whenever I create my rectangular object on ADPL when I set it to axisymmetric it turns into a cylinder. Does anybody know how to solve this problem?

The 3D geometry of a rectangle where one edge is on the axis of revolution is a cylinder.

The solution to your problem is that the flat steel rigid cylinder can only push against a cylindrical sample in an Axisymmetric model.

Instead of a 15x15x10 rectangular sample, you would draw a 7.5 mm wide x 10 mm tall rectangle, and it will become a 15 mm diameter x 10 mm thick sample.
