I'm making a fort and I have made half and mirrored it. And I've made the first side view. Then I've added array with a count of 4 to complete the 4 sides like a square shape. I added an empty and rotate it by 90 degree. The problem is when I rotate, all sides do not match perfectly or are not aligned in square and some gap is created. The top 2 round circle when array should give 4 corners it's giving 8 corners.
