Creating random shapes is an exciting aspect of Adobe Illustrator that lets you explore artistic impulsivity while maintaining precise vector control. Whether you're generating irregular forms for personal art pieces or professional design projects, learning how to produce random shapes in Illustrator is a valuable skill to have.
In this comprehensive guide, we will explore various methods to create random shapes in Illustrator. By the end, you'll have plenty of ideas and techniques to inspire your graphic design journey. Let's dive in!
Using the Paintbrush Tool
The Paintbrush tool offers a wide range of 'brush library' options featuring various random shape effects. You can experiment with different presets or custom-create your brush profile for unique results.
First, select the Paintbrush tool (B). Choose a brush style from the Brushes panel (Window > Brushes). To create a new brush, click on 'New Brush' and explore the various brush settings. Once you've found your desired brush, click on 'Done'. Draw your random shape using the Paintbrush tool.
Working with the Wacom Tablet
Combine the Paintbrush tool with a Wacom tablet for enhanced control and tactile creativity. Switch to the Pressure option in the Brushes panel, allowing you to vary the brush size as you draw, creating seemingly random shapes effortlessly.
Using a Wacom tablet also enables you to tilt and rotate brushes for even more unpredictable results. Enable 'Tilt' and 'Rotation' in the Brushes panel, and try drawing random shapes with these settings adjusted.
Leveraging the 3D Effects
Illustrator's 3D effects can generate captivating random shapes by manipulating objects in a three-dimensional space. Although this method might seem complex, it's surprisingly simple to create intriguing shapes with just a few clicks.
Extrude & Bevel
Start by creating a simple shape, then apply the Extrude & Bevel effect (Effect > 3D > Extrude & Bevel). Adjust the depth, surface, and lighting settings to achieve the desired random shape. Click 'OK' to apply the effect.
Animate the shape further by rotating it in the 3D workspace (Object > Transform > Rotate). Alternate between two-dimensional and 3D views to fine-tune your design, creating an unpredictable, unique shape or graphic.
Bevel & Emboss
Apply the Bevel & Emboss effect (Effect > Stylize > Bevel & Emboss) to your shape to add depth and dimension. Experiment with style, technique, and size to create random, textured effects.
To generate even more varied shapes, combine multiple 3D effects and manipulate them simultaneously. For example, apply an Extrude & Bevel effect first, and then add a Bevel & Emboss effect on top for a strikingly random, three-dimensional appearance.
Finally, don't be afraid to step away from your work, take a break, and approach your designs with fresh eyes. You might justfind the inspiration to create a truly unique, random shape that captivates you, your client, or your audience.
