I have just started off with blender, so please forgive me if I misuse the terminologies.
I have created an object by merging together a cylinder and a cube as shown in the screenshots below. I created edge loops to sharpen the corners, which worked fine. It caused some deformities at the top face of the cylinder which I fixed by creating an inset.
Is there a way to deal with this? It seems that this must be a very common scenario.
