AutoCAD 2007, while older, still holds its own for many users. Knowing how to create simple shapes like arrows is fundamental. This guide will walk you through several methods for drawing arrows in AutoCAD 2007, from the simplest to more customizable options. We'll cover using the LINE command, the POLYLINE command, and utilizing blocks for efficient reuse.

Method 1: Drawing an Arrow with the LINE Command

This is the most basic approach, suitable for quick, simple arrows.

Step 1: Start the LINE Command: Type LINE (or L) in the command line and press Enter.

Step 2: Specify the First Point: Click the starting point of your arrow in the drawing area.

Step 3: Specify Subsequent Points: Click to define the shaft of the arrow. For a straight arrow, just click once for the arrowhead's base.

Step 4: Create the Arrowhead: Click two more points to form the arrowhead. The more points you use, the more accurate the arrow will appear. Experiment to get the desired angle.

Step 5: End the Command: Press Enter to finish the line command.

This method is straightforward but requires precise clicking for accurate arrowheads. It's not ideal for creating multiple identical arrows.

Method 2: Using the POLYLINE Command for Smoother Arrows

The POLYLINE command allows you to create a smoother arrowhead than you can with individual lines.

Step 1: Start the POLYLINE Command: Type POLYLINE (or PL) and press Enter.

Step 2: Specify the First Point: Click the starting point of your arrow.

Step 3: Define the Arrow Shaft: Click to define points along the arrow shaft.

Step 4: Create the Arrowhead (Arc): Instead of individual lines, use the arc segment of the polyline to create a curved arrowhead. You'll need to specify the arc's start point, endpoint, and center. AutoCAD will assist you in positioning these.

Step 5: Close the Polyline: When you've completed the arrowhead, use the C command (for Close) to connect the end of the arrowhead to the shaft's endpoint. Press Enter to finish.

Method 3: Creating and Using an Arrow Block

This is the most efficient method for creating and reusing arrows consistently.

Step 1: Draw Your Arrow: Use either the LINE or POLYLINE command (as described above) to create a single arrow of your desired style and size.

Step 2: Create a Block: Select the arrow. Type BLOCK (or B) in the command line and press Enter.

Step 3: Define the Block Name: Choose a descriptive name for your block (e.g., "Arrow"). Specify the insertion point (typically the arrow's base). Press Enter.

Step 4: Inserting the Block: Once the block is created, you can insert it repeatedly into your drawing using the INSERT (or I) command, selecting your "Arrow" block and specifying its location.

This method ensures consistency and saves time when you need multiple arrows.

How to Customize Arrow Appearance

Regardless of your chosen method, AutoCAD offers many customization options:

• Line Weight: Adjust the line weight (thickness) of the arrow for better visibility.
• Line Type: Experiment with different line types (e.g., dashed lines) to change the arrow's appearance.
• Color: Change the color of the arrow to suit your drawing.
• Layer Management: Assign the arrow to a specific layer for organization.

Troubleshooting Tips

• Snapping: Ensure your snap settings are appropriate for precise arrow creation.
• Object Snap: Utilize object snaps (endpoint, midpoint, etc.) for accurate point selection.
• Zoom and Pan: Use the zoom and pan tools to easily navigate your drawing area.

By mastering these techniques, you can easily create professional-looking arrows in your AutoCAD 2007 drawings. Remember to save your work frequently!
