How to Resize Multiple Objects in AutoCAD?

Understanding the Resize Process for Multiple Objects in AutoCAD

AutoCAD offers various methods to resize multiple objects efficiently. This guide outlines the steps needed to perform scaling tasks, ensuring that your drawings retain their integrity while adjusting to your desired dimensions.

Prerequisites Before Scaling Objects

1. Open Your Drawing: Begin by launching AutoCAD and opening the drawing that contains the objects you wish to resize.
2. Select Objects: Familiarize yourself with the selection methods available, such as using selection boxes or by clicking individual objects.

Step-by-Step Guide to Resize Multiple Objects

Using the Scale Command

1. Activate the Scale Command: Type SCALE in the command line and hit Enter.
2. Select the Objects: Click to select all objects you wish to resize. Once your selection is complete, press Enter.
3. Define the Base Point: Choose a base point for scaling. This is crucial as it determines the point about which the objects will resize.
4. Enter the Scale Factor: Input the scale factor. For example, entering "2" will double the size of your selected objects, while "0.5" will reduce their size by half.
5. Confirm Changes: After entering the scale factor, review your objects to ensure they have resized correctly.

Centering Scale on Individual Objects

1. Load Lisp Routine: To scale each object based on its bounding box center, load the LISP routine designed for this function.
2. Run the Command: After loading, type SAC and press Enter to initiate the scaling process.
3. Select Objects: Just like before, select all the objects you wish to resize and confirm your selection.
4. Evaluate the Result: Make sure every object reflects the new size accurately, considering their individual centers.

Scaling Without Moving the Objects

1. Access the Drafting Tab: Navigate to the Drafting tab and choose the Modify panel.
2. Select Multiline Text Objects: If resizing multiline text, select the objects and press Enter.
3. Specify Justification: Decide whether to keep existing text justification or choose a new option. Press Enter to confirm.
4. Input Scale Factor: Type “s” and then enter the scale factor to apply to each selected text object.

Advanced Editing: Resizing Block Objects

1. Select the Block: Use the Select Objects tool to highlight the block you want to modify.
2. Edit Properties: Click the Open Object button to access the block settings.
3. Adjust Height and Width: Navigate to the Size section and set both the Height Factor and Width Factor to your desired values.
4. Apply Changes: Confirm the adjustments by clicking OK.

FAQs

1. What if my drawing appears too small in AutoCAD?
First, set appropriate limits by typing LIMITS in the command line. Then, use Z followed by A to zoom all the content into view. This procedure can help visualize the drawing correctly.

2. Can I resize a specific dimension of multiple objects at once?
AutoCAD does not provide direct options to scale dimensions independently for multiple objects simultaneously. You would need to resize each object individually or use specialized LISP routines designed for that purpose.

3. How do I select multiple objects effectively in AutoCAD?
To select multiple items, hold down the Shift key while clicking to add each item to your selection. Alternatively, use selection or crossing windows to include multiple objects at once. This method can be more efficient for larger compositions.
