How to Use Stretch in AutoCAD 2020

Understanding the Stretch Tool in AutoCAD 2025

The Stretch tool in AutoCAD is an essential feature that allows you to modify the geometry of existing objects, particularly by adjusting vertices and endpoints without altering the entire shape. This article provides a detailed, step-by-step guide on how to effectively use the Stretch tool in AutoCAD 2025.

Accessing the Stretch Tool

1. Activate the Command: Start by typing STRETCH in the command line and press Enter. Alternatively, you can find the Stretch tool on the Modify panel in the Home tab.

2. Selection Method: Once the command is activated, you will need to select the objects you wish to stretch. You can use the crossing selection method by dragging a box from right to left. Objects that intersect the box will be selected. It’s important to know that only the parts of the objects completely enclosed by the selection will be affected.

3. Completing Selection: After making your selection, press Enter to confirm.

Stretching the Selected Objects

1. Base Point Specification: Next, you will need to specify a base point. This point serves as a reference for how far you will pull or push your selected geometry. Click on the point that you want to establish as your base.

2. Movement Direction: After selecting the base point, move your cursor in the direction you wish to stretch the selected objects. You can either enter a specific distance in the command line or click a point in the drawing area to define how far you want to stretch.

3. Finalizing the Command: Once you have defined the stretch distance, click to place the new endpoint or press Enter to complete the action.

Stretching Blocks in AutoCAD 2025

1. Access Block Authoring Palette: To stretch a block, you need to open the Block Authoring palette. Click on the Actions tab and select Stretch.

2. Select Parameter: Follow the prompts in the command line to select the parameter you want to associate with the action, such as the Distance1 parameter.

3. Specify Parameter Point: Click on the parameter grip or define start and end points as needed.

Handling Polylines and Groups

Stretching Polylines

1. Choosing a Polyline: Select the polyline you intend to stretch.

2. Grip Selection: Hover over the endpoint grip needing adjustment.

3. Initiate Stretch: Choose either “Stretch” or “Stretch Vertex” depending on your version. Specify your base point and adjust the endpoint grip accordingly.

Stretching Groups

1. Multiple Object Selection: Select multiple objects that you want to stretch simultaneously.

2. Grip Management: Hold Shift and click on the grips to highlight them. Choose one grip to be the base point.

3. Final Adjustment: Move the cursor to stretch as intended and click to confirm the new position.

Common Use Cases for the Stretch Tool

The Stretch tool can be particularly useful when modifying existing designs, such as updating dimensions, adjusting layouts, or refining shapes in drawings. Mastery of this tool enhances overall efficiency and precision in drafting.

Frequently Asked Questions
