2D Axial Symmetry Simulation rotation only 90degree

Hi,

My name is Jaehoon and I am designgin acoustic transdecer.

I was trying to run 2D axial symmtry only to rotate 90 degree not 360 degree but I do not know how to do it.

For example, If I draw a square and rotate 360 degree along with z axis the result will be a cylinder . However, I would like to achieve something pie shpaed figure by rotating the same square only 90degree.

I have tried 3D simulation but it takes too much time for simulation.

Is there any possible way to rotate only a certain amount of degree, not 360?

Thanks for helping in advance.
