I have attached a picture of the perforated cylinder which I needed to draw like it? I am using this cylinder in electrochemical module

Using only the drawing tools within Comsol, I would be able to create that geometry by building multiple cylinders and using the array and difference operations.

You should consider whether (1) the holes are essential to the problem you want to solve and (2) whether symmetry can be used to reduce the effort of drawing and computing the problem.

yes the holes are essential and affect the process greatly and the symmetry can be used. I want this holes to be 2D circles and to create a polar array and I can't do this 2 actions. Can you clarify how symmetry would help? Can you please write the actions in details as the geometry is the base for the simulation in my case? Thank you so much
