   • If straightening is required, type "Straighten" and press Enter.

Creating Curved Lines in AutoCAD

1. Activate the Line Tool: Begin by selecting the Line tool from the Draw panel.
2. Select Curve Options: Depending on the version, select ‘Arc’ for drawing curves. Alternatively, use the ‘Spline’ tool for more complex curves.
3. Specify Points: Click to define the start point and specify the endpoints or control points on your canvas.
4. Use Control Points for Adjustments: For splines, you can modify the curve by dragging control points to the desired locations.

Generating 3D Curves in AutoCAD

1. Navigate to the 3D Sketch Tab: Open the 3D Sketch tab and look for the Draw panel.
2. Select the Helical Curve Tool: Find the Helical Curve option to start creating 3D curves.
3. Define Parameters: In the dialog box, set your desired dimensions and types for the helix.
4. Adjust and Confirm Settings: Enter specific values based on the curve’s requirements, such as radius and height.

Utilizing the REGenerate Command

1. Open the View Tab: Click on the View tab in the main menu.
2. Locate the Regenerate Option: Find the Regenerate drop-down under the Appearance panel.
3. Execute the Command: Click on ‘Regenerate Model’ and opt to select specific objects or regenerate the entire drawing by pressing Enter.

Understanding the ARC Command

1. Select the ARC Command: Access the command box and type "ARC".
2. Choose Parameters: Specify the various inputs such as center point, radius, or start and end angles for the arc.
3. Draw the Arc: Click to create the arc based on the parameters provided.

Drawing Free-Hand Curves in AutoCAD

1. Initiate the Sketch Command: Type ‘Sketch’ into the command prompt.
2. Confirm Sketching Settings: Accept the default settings by pressing Enter.
3. Use Your Cursor to Draw: With your mouse, begin sketching the freehand curve by clicking at various points.
4. Pause or Complete the Sketch: Click to cease sketching, then press Enter to finish.

Employing MLINE for Multiple Line Drawing

1. Type MLINE: Enter the MLINE command in the command prompt to activate the multiline feature.
2. Select Line Style: Enter ‘st’ to choose or review available styles.
3. Justification and Scale: Adjust the justification using ‘j’ and set the scale by entering ‘s’, followed by your desired scale.

Exploding Objects in AutoCAD

1. Command for Exploding: Use the ‘EXPLODE’ command to break down complex objects into their basic components.
2. Select Object: Click on the object you want to explode, such as a block or polyline.
3. Confirm Explode Action: Execute the command to alter the object for separate modifications.

FAQs
