How to Use Stretch Function in AutoCAD?

Understanding the Stretch Command in AutoCAD

The Stretch function in AutoCAD is a powerful tool designed for modifying parts of geometric shapes. This command allows users to alter the dimensions of selected objects by enveloping them in a selection polygon or window. Unlike other commands that may move entire objects, Stretch specifically adjusts segments that fall within the selection area. Objects not fully enclosed, such as ellipses, blocks, and circles, respond differently and will be shifted rather than reshaped.

Steps to Use the Stretch Command

To effectively use the Stretch command, follow these detailed steps:

  1. Select the Command: Type STRETCH in the command line or find it in the Modify panel of the Home tab.
  2. Create a Selection: Define the area by using the polygon selection or crossing window. Ensure that the part of the object you want to stretch falls within this selection.
  3. Confirm Selection: Press Enter to confirm the selection of the object segments you intend to modify.
  4. Indicate the Stretch Direction: Click and drag the mouse to indicate the direction and distance of the stretch. You can also input a specific distance if preferred.
  5. Finish Command: Press Enter to finalize the operation and visualize the modified object.

Stretching Dimensions in AutoCAD

Stretching dimensions in AutoCAD provides the ability to modify the size of your dimensioning accurately. Here are the steps to accomplish this:

  1. Access the Dimension Tool: Navigate to the Annotate tab, find the Dimension panel, and click on the drop-down menu to select Linear or Symmetric Stretch.
  2. Start the Stretching Process: Press Enter to initiate the command.
  3. Select Dimension Text: Click on the text of the dimension you wish to stretch.
  4. Enter Stretch Value: Input the desired stretch value, either numerically or by dragging the mouse.
  5. Select Associated Objects: Choose the specific objects you want to stretch in conjunction with the dimension by using a crossing window selection.

Stretching Multiple Objects

To stretch multiple items simultaneously, adhere to the following steps:

  1. Select Multiple Objects: Click to select several items you want to stretch.
  2. Highlight Grips: While holding down the Shift key, click on the grips of the objects you wish to highlight.
  3. Choose Base Grip: Release the Shift key and select a grip that will serve as the anchor for the stretch operation.
  4. Stretch the Objects: Move your pointing device in the desired direction and click to complete the stretch.

Stretching a Rectangle in AutoCAD

For those looking to stretch rectangles specifically, follow these steps:

  1. Initiate Rectangle Command: Access the Home tab, navigate to the Draw panel, and select the Rectangle tool.
  2. Define the Corner: Specify the initial corner point of the rectangle you wish to stretch.
  3. Select Stretch Command: Utilize the STRETCH command to adjust the rectangle’s dimensions.
  4. Execute the Stretch: Surround the rectangle with a selection box and follow the earlier noted steps for stretching an object.

FAQ

1. What happens if I try to stretch an object not enclosed in the selection window?

Objects that are not fully enclosed by the selection window will be moved rather than stretched, preserving their original shape while shifting their position.

2. Can I stretch 3D objects in AutoCAD?

Yes, stretching 3D objects can be performed using the same selection methods. You can create a crossing window around the 3D object and specify the stretch distance using the mouse or the command line.

3. Is it possible to stretch dynamic blocks in AutoCAD?

Dynamic blocks can be stretched within the block editor. Use the Stretch tool within the block authoring palette to set specific stretch distances based on defined parameters.
