2. Adjust Positions:
   • Position the items along the defined path to achieve the desired layout.

FAQs

Q1: What is the difference between polar and rectangular arrays in AutoCAD?
A1: Polar arrays arrange objects in a circular formation around a center point, while rectangular arrays align them in rows and columns in a straight pattern.

Q2: Can I undo changes made to an array?
A2: Yes, you can use the Undo command (Ctrl + Z) to revert any changes made to the array.

Q3: How do I edit a component of an array without affecting others?
