Okay, here is the exact answer to the question 'How do you straighten something in AutoCAD?'.
In AutoCAD, while there isn't a single command literally named "Straighten," the most common method to achieve this effect is by using the ALIGN command. This command allows you to align selected objects with other geometry or specific points in your drawing, effectively straightening them relative to a desired orientation (like horizontal, vertical, or aligned with another line).
Here’s how you typically use the ALIGN command, incorporating information from the provided reference:
The ALIGN command lets you move, rotate, and scale objects to match the orientation and position of other objects or points. This is particularly useful for straightening objects that are off-axis or rotated incorrectly.
Steps to Align (Straighten) Objects
Based on the reference provided, the initial steps are:
- Locate Objects: In your open drawing, locate the objects you want to align or straighten.
- Access Command: On the ribbon, click the Home tab, then the Modify panel (you might need to expand it to see all options), and click Align.
- Select Objects: Select the objects you want to align and press Enter.

After selecting the objects as described in the reference, the command prompt will guide you through specifying source points on the object(s) you are straightening and corresponding destination points where you want those source points to go.
Here are the subsequent steps to complete the ALIGN command:
- Specify First Source Point: Click on a point on the object(s) you want to move/rotate/straighten.
- Specify First Destination Point: Click on the point in the drawing where the first source point should move to. This could be a point on existing straight geometry.
- Specify Second Source Point: Click on a second point on the object(s). This point, along with the first source point, defines the initial orientation.
- Specify Second Destination Point: Click on a second point in the drawing. This point, along with the first destination point, defines the desired straight orientation. By defining two points, you dictate how the object will rotate. For example, aligning two points on a rotated line to two points on a horizontal line will straighten the first line horizontally.
- Specify Third Pair of Points (Optional): You can specify a third pair of points for 3D alignment. For straightening in a 2D plane, you typically just press Enter.
- Scale Objects (Optional): AutoCAD will ask if you want to scale the objects based on the distance between the first two destination points. Choose No (N) to only align and rotate, or Yes (Y) if you also want to change the object's size to match the distance between the destination points.
Once completed, the selected object(s) will be moved and rotated according to the points you specified, effectively "straightening" them to the desired orientation defined by your destination points.
Practical Applications
Using the ALIGN command is a powerful way to fix geometry issues:
- Straighten a Rotated Line: Align the endpoints of a crooked line to two points defining a horizontal or vertical line.
- Align a Block: Align insertion points or corners of a block to be perfectly in line with other features.
- Arrange Objects: Align multiple objects along a path or baseline.
| Step Number | Action | Location (Ribbon) | Command Line Equivalent |
|---|---|---|---|
| 1-3 | Select Objects | Home Tab > Modify Panel (Expanded) > Align | ALIGN or AL |
| 4-9 | Specify Points/Scale | (Follow command prompts) | (Follow command prompts) |
By carefully selecting your source and destination points, you can precisely control how objects are straightened and positioned in your AutoCAD drawing.
