Symmetry has captivated artists and observers throughout history. From the mirror-image mosaics of the ancient Persians and Romans, to the dizzyingly intricate tile patterns of Islamic art, to the circular stained glass rose windows of Gothic cathedrals, symmetrical designs can be found across cultures and mediums. Modern artists continue to explore symmetry, producing mesmerizing works like the kaleidoscopic digital mandalas of Android Jones or the billowing Rorschach inkblots of Bruce Riley.

So what is it about symmetry that so entrances the human eye and mind? Mathematically, symmetry describes a pattern that remains unchanged when transformed in certain ways, such as being rotated, reflected, or translated. We perceive symmetrical forms as balanced, harmonious, and orderly in a chaotic world. Symmetry underlies the geometry of nature, from the branching fractals of trees to the radial segments of starfish, while asymmetry characterizes organic life and movement. In art and design, symmetry provides a structural framework to build upon or deliberately disrupt.

Today, digital tools like PaintTool SAI make it easier than ever for artists to create perfectly symmetrical drawings with a few clicks, no ruler or compass required. In this in-depth guide, I‘ll show you multiple ways to harness the power of symmetry in PaintTool SAI, from simple one-click mirroring to intricate radial tessellations. Whether you‘re a symmetry enthusiast or a digital art beginner, read on to learn all the techniques you need to start exploring this fundamental artistic principle in your own work.

## Rapidly Reflect: Making Mirrored Drawings with the Symmetric Ruler

PaintTool SAI‘s Symmetric Ruler is a fast, intuitive way to create drawings that mirror along a central axis. Here‘s how to set it up:

1. Go to Layer > Ruler > New Symmetric Ruler. A straight line splitting your canvas will appear.
2. To move the ruler, hold Ctrl and drag it to the desired location.
3. To rotate the ruler to a diagonal angle, hold Alt while dragging one endpoint. The line will pivot around the center point.
4. Draw on one side of the line and watch it instantly mirror on the opposite side, like a reflection in water.

Advanced Symmetric Ruler tips:

- Adjust your brush size smaller as you get closer to the center line for a neater mirror image.
- Hold Shift while moving the ruler to snap it to 15 degree angle increments for precise diagonal positioning.
- To draw symmetrically in only one direction, hold down Ctrl+Alt and drag the ruler to reposition it without changing the angle.
- You can also create ruler presets with specific positions/angles to reuse later. After positioning your ruler, go to Layer > Ruler > Register Ruler to save it.

One significant advantage of the Symmetric Ruler is the ability to quickly sketch symmetrical poses and anatomy for character designs. Map out a character‘s basic form and stance on one side, then detail and refine it while the opposite side mirrors instantly. This is much faster than drawing both sides freehand! For hyper-symmetrical characters like robots, using the ruler ensures the left and right halves match exactly.

## Rotation Relation: Using Radial Symmetry to Create Mandala Patterns

Radial or rotational symmetry occurs when a pattern repeats around a central point, like spokes on a wheel or petals on a flower. PaintTool SAI‘s Symmetric Ruler can also generate designs with radial symmetry:

1. Create a new Symmetric Ruler (Layer > Ruler > New Symmetric Ruler).
2. Double-click the center point of the ruler to open the Symmetry Ruler settings.
3. Under Divisions, increase the number to split your canvas into equal pie slices, like cutting a pizza. Each slice will mirror the others.
4. Uncheck "Enable line symmetry" to disable the straight line reflection. Now you have a blank slice to fill.
5. Draw within a single slice. Your strokes will simultaneously appear in every other slice, radiating from the center point.

Some key things to keep in mind with radial symmetry:

- The more divisions you create, the narrower each slice will be. Stick to 6-12 divisions max for a balance between complexity and workability.
- For fuller patterns, position elements like dots and lines slightly unevenly throughout the slice, avoiding the exact center and edges.
- To create overlapping petal or mandala layers, make a new Symmetry Ruler and decrease its size to fit a smaller ring. Repeat your pattern in this new circle.
- Don‘t feel limited to abstract geometric designs! Radially symmetrical figures also appear in nature, like jellyfish and sea stars. You can mirror an organic shape for an artistic study.

Did you know? The psychologist Carl Jung saw circular mandalas as representative of the Self archetype and used mandala drawing as a tool for self-discovery and personal growth. Many adults today find drawing and coloring symmetrical patterns to be a meditative, stress-relieving practice. Digital mandala drawing with PaintTool SAI can be a relaxing hobby with the added bonus of easily saveable, infinitely recolorable designs!

## Fabulous Flips: Mirroring Freehand Drawings with the Transform Tool

For those who prefer a more freeform approach, you can also mirror completed drawings or design elements using PaintTool SAI‘s Transform and Flip functions. This method works well for designs that aren‘t perfectly symmetrical to start with.

1. Draw half of your design on a single layer. Don‘t stress about perfect symmetry in this initial sketch.
2. Use the Selection tool or press Ctrl+A to select your drawing.
3. Copy (Ctrl+C) and Paste (Ctrl+V) your selection. It will appear on a new layer.
4. With the pasted layer active, go to Edit > Transform or press Ctrl+T. In the Transform window, choose Flip Horizontal or Flip Vertical.
5. Reposition the flipped selection to line up with your original, creating a complete mirrored design. Hit Enter to confirm the transformation.
6. Merge the two layers (Layer > Merge Visible) and clean up any area where the two halves join using the Eraser tool.

Useful Transform tool tips:

- For faster mirroring, memorize the shortcut keys. Ctrl+Left/Right Arrow flips the selection horizontally, Ctrl+Up/Down Arrow flips it vertically.
- Hold Shift while resizing a selection to maintain its aspect ratio and avoid distorting the mirrored copy.
- When positioning a flipped element next to the original, hold Ctrl to temporarily switch to the Move tool. With Snap to Grid enabled (File > Preferences > Grid), you can precisely align the pieces.
- To create crystalline compositions or abstract ink blots, repeat the copy-flip process multiple times in different directions for increasingly complex symmetry.

Here‘s a fun fact: Studies show that the human brain processes symmetrical and asymmetrical designs differently. Symmetrical images with a vertical axis are perceived more quickly and easily than asymmetric ones. Scientists hypothesize that our visual systems evolved to rapidly recognize faces and potential threats, both of which often exhibit vertical bilateral symmetry. So embracing symmetry in art and design can create eye-catching, instinctively appealing compositions!

## Breaking the Mirror: Incorporating Asymmetry and Combining Symmetry Types

Once you‘ve mastered the basics of creating symmetrical drawings in PaintTool SAI, you can start exploring more advanced techniques:

- Disrupt an otherwise symmetrical design with a single asymmetric focal point, like a single different colored gem in a symmetrical cluster, or a graceful curving stroke intersecting a radial grid.
- Introduce slight variation between mirrored elements for an uncanny, organic feel, like the imperfect symmetry of leaves or butterfly wings. Alter the color, size, or angle of some repeated motifs.
- Combine different types of symmetry in one artwork. Fill a larger bilaterally symmetrical shape with a radial pattern, or mirror and rotate the same element in different directions for a dizzying abstract effect.
- Use symmetry to convey narrative and emotion. A perfectly symmetrical portrait can seem serene and idealized, while a fractured, misaligned reflection evokes inner turmoil.

According to mathematician Frank Farris, an aesthetic "sweet spot" exists in the balance between boring total symmetry and confusing total asymmetry. He argues the most visually interesting designs are those with just enough symmetry to establish an orderly pattern, then strategically break it. As you grow more confident with symmetrical drawing, strive to find your personal sweet spot between order and chaos!

## Reflections on Symmetry: Conclusion and Artist Inspiration

"The universe is built on a plan the profound symmetry of which is somehow present in the inner structure of our intellect." – Paul Valery

As we‘ve explored in this guide, symmetrical drawing in PaintTool SAI is both creatively inspiring and surprisingly easy with tools like the Symmetry Ruler and Transform functions. You now have the power to rapidly generate perfectly mirrored and radially balanced designs, or to strategically disrupt symmetry for artistic effect. The techniques may be digital, but the underlying mathematical and aesthetic principles of symmetry are universal.

I challenge you to start seeing symmetry everywhere – in the human face, in architectural ornamentation, in the spiral of a nautilus shell. Train your artist‘s eye to spot both symmetry and asymmetry in the world around you, then express your unique interpretation in PaintTool SAI.

As a final creative prompt, here are some of my favorite recent examples of artists innovating with digital symmetrical art:

- The endlessly scrolling, algorithmically generated symmetries of Rafael Araujo‘s Fibonacci spiral studies
- Seb Lester‘s calligraphic butterfly letterforms with a modern, asymmetric twist
- Erica Hinyot‘s vibrant, neon-hued mandala series exploring themes of connection and growth
- The hypnotic video loops of Sucuk und Bratwurst‘s 3D fractals and radial blooms

Seek out artists who inspire you, analyze how they utilize symmetry in their work, then put your own spin on it. As you master symmetrical drawing and patterning with PaintTool SAI, you‘ll be amazed at how many designs and variations are possible – a single line or shape can birth infinite forms. Like a kaleidoscope, the tiniest change can shift the entire picture into something new.

So dive into the world of digital symmetrical drawing with confidence and curiosity! Save and share your experimentations. And feel free to revisit this guide as a technical and inspirational refresher, whenever you need a little boost of symmetry in your art-making. Just as the ancient principle of symmetria describes a harmony of proportions, I hope exploring symmetry brings a sense of balance, beauty, and endless possibility to your digital art practice.
