Frequently Asked Questions

1. Can I resize multiple objects at once in AutoCAD?
Yes, you can select multiple objects and apply the scaling or stretching commands collectively to resize them as needed.

2. What should I do if my rectangle doesn’t resize as expected?
Ensure that you have entered the dimensions correctly and that the object snapping mode is enabled for precise selection.

3. Is it possible to return the size of an object back to its original dimensions?
Yes, you can use the UNDO command immediately after resizing to revert to the previous state. Alternatively, you can manually re-enter the original dimensions if known.
