How to Use Stretch in AutoCAD 2018?

Understanding the Stretch Command in AutoCAD 2025

Stretching objects in AutoCAD is a fundamental editing function that allows users to modify the shape and size of various entities. This command is particularly useful when you need to adjust specific portions of objects without altering the entire design.

Initiating the Stretch Command

1. Begin by navigating to the Home tab on the ribbon.
2. Locate the Modify panel.
3. Click on the Stretch icon to activate the command. Alternatively, you can type STRETCH in the command line and press Enter.

Selecting the Objects

4. When prompted to select objects, use a crossing window selection method. This involves dragging a selection box from right to left, ensuring that at least one vertex or endpoint of the objects you want to stretch is included within the selection window.
5. After making your selection, press Enter to confirm.

Defining the Displacement

6. You will then be prompted to specify a displacement. This can be done in several ways:
   • Cartesian coordinates – Enter the X, Y (and Z, if applicable) values directly.
   • Polar coordinates – Specify the distance and angle.
   • Cylindrical or spherical coordinates – Use these methods if you are working in 3D.

Stretching Specific Parts of an Object

Using Grips for Stretching

1. Select the object you wish to modify.
2. Grips appear as small squares on the vertices and midpoints of the object.
3. Hold the Shift key and click on the grips you want to stretch. Ensure that the grips remain highlighted.
4. Release the Shift key and select a base grip by clicking on it.
5. Move your cursor in the desired direction and click to finalize the stretch.

Stretching Dimensions in AutoCAD

1. Access the Annotate tab.
2. From the Dimension panel, use the drop-down to select Linear/Symmetric Stretch.
3. Press Enter to begin the command.
4. Click on the dimension text of the object whose dimension you want to stretch.
5. Input the stretch value for that dimension.
6. Use a crossing window selection method to select the object and the associated dimension you just manipulated.

Modifying Rectangles and Other Shapes

To stretch a rectangle, select it using the above methods as needed. Adjusting the shape can be done using the grips or by utilizing the Stretch command. The stretching action will apply to all selected points within the specified area.

Stretching Blocks in AutoCAD

1. Open the Block Editor for the block you intend to stretch.
2. Create or select a rectangle, and choose the Linear Stretch option from the Block Authoring Palette.
3. Define the parameters for the stretch operation, and apply the stretch command accordingly.

FAQs

1. Can I use the Stretch command for multiple objects at once?
Yes, you can stretch multiple objects simultaneously by selecting them all within a crossing window. Just ensure you include at least one vertex or endpoint of each object.

2. Is it possible to undo a stretch operation if I make a mistake?
Absolutely. If you accidentally stretch an object incorrectly, you can use the Undo command by typing U in the command line, or by selecting Undo from the Edit menu.

3. Can the Stretch command modify 3D objects in AutoCAD?
Yes, the Stretch command can also be applied to 3D objects. However, be sure to switch to a proper 3D view mode for precise manipulation of 3D entities.
