How to Draw Polygon in AutoCAD: Step-by-Step Guide

To draw a polygon in AutoCAD, use the POLYGON command, specify the number of sides, and then choose whether to inscribe or circumscribe the polygon around a circle. You then define the polygon's center and size by clicking or entering coordinates and dimensions.

Syntax

The basic syntax for drawing a polygon in AutoCAD is:

• POLYGON - Starts the polygon drawing command.
• Number of sides - Enter how many sides the polygon will have (minimum 3).
• Inscribed in circle / Circumscribed about circle - Choose if the polygon fits inside or outside a circle.
• Center of polygon - Specify the center point by clicking or typing coordinates.
• Radius or Edge length - Define the radius of the circle that the polygon is inscribed or circumscribed around, or specify the edge length if choosing the edge option.

plaintext

POLYGON
<number_of_sides>
I or C
<center_point>
<radius_or_edge_length>

Example

This example draws a hexagon (6-sided polygon) inscribed in a circle with a radius of 5 units centered at the origin.

plaintext

Command: POLYGON
Enter number of sides: 6
Enter an option [Inscribed in circle/Circumscribed about circle] <Inscribed>: I
Specify center of polygon or [Edge]: 0,0
Enter an option [Radius]: 5

Output

A 6-sided polygon (hexagon) appears centered at (0,0) with each vertex touching a circle of radius 5 units.

Common Pitfalls

• Not specifying the number of sides correctly (must be 3 or more).
• Confusing inscribed and circumscribed options, which changes polygon size.
• Entering incorrect center coordinates causing the polygon to appear off-screen.
• Forgetting to specify radius or edge length, which stops the command.

Always double-check inputs and use object snaps to place the polygon accurately.

plaintext

Wrong way:
POLYGON
2  ; Invalid number of sides

Right way:
POLYGON
5  ; Valid number of sides

Quick Reference

Tips for drawing polygons in AutoCAD:

• Use POLYGON command to start.
• Minimum sides: 3.
• Choose Inscribed to fit polygon inside circle.
• Choose Circumscribed to fit polygon outside circle.
• Specify center point carefully.
• Use radius or edge length to size polygon.

Key Takeaways

Use the POLYGON command and specify the number of sides to draw polygons in AutoCAD.

Choose between inscribed or circumscribed options to control polygon size.

Always enter a valid center point and radius or edge length to complete the polygon.

Minimum polygon sides must be 3; entering less will cause errors.

Use object snaps to place polygons accurately on your drawing.
