How to use Shape Builder to build a clean geometric planet logo in 5 steps

Before a logo ever becomes a polished, downloadable mark, it usually starts as a handful of simple shapes. Circles, rectangles, arcs — nothing glamorous.

The magic happens when you combine those shapes into something cleaner, more intentional, and more professional. That’s exactly the kind of control you get when working with vectors, which is why tools like Kittl’s Shape Builder and the rest of our vector editing features matter so much.

For this tutorial, we’ll build a logo inspired by a clean astronomy mark. And yes — everything in this symbol comes from basic geometry. Your only job is to reshape, merge, subtract, and refine simple forms until they come together as one cohesive silhouette.

Understand the geometric planet logo you’re trying to build

Before you start merging shapes, you need to know exactly what you’re building. The astronomy logo we’re working with looks sleek and polished.

But underneath it all, it’s just a smart arrangement of basic geometry. Break it down and you’ll see:

• The planet: one perfect circle acting as the anchor of the entire mark.
• The orbit ring: two long ellipses crossing the planet, then trimmed with Subtract to create that clean, cut-out band.
• The comet arc: a wide curved shape formed by uniting a large arc and a small pointed triangle.
• The star: a simple four-point form, from star shapes
• The orbiting dots: a few small circles placed off to the side to keep the composition balanced and give it a sense of motion.

Once you see the logo as a handful of circles, ellipses, and triangles, the Shape Builder tool starts to feel a lot less intimidating.

Step 1: Block out the entire geometric planet logo composition using only basic shapes

Start by building the rough skeleton of your astronomy logo. Don’t worry about perfection yet. This phase is all about getting the right shapes in the right places.

1. Start with a large circle for the planet.
2. Add a long ellipse cutting across the circle to form the top edge of the orbit ring.
3. Duplicate or draw a second ellipse to shape the bottom curve of that same ring.
4. For the comet-like sweep above the planet, switch to the Pen Tool. Since you’ve already learned how to handle basic curves, this is the perfect moment to draw a smooth arc and then angle it slightly so it feels like it’s swooshing around the planet.
5. Place a few small circles for the orbiting dots.
6. Create a star using a polygon set to four points.

At this stage, your screen should look messy and full of overlapping shapes. You want raw material to work with before the Shape Builder tool turns it into one cohesive logo.

Step 2: Build the comet swoosh

1. Use the Pen Tool to draw the entire swoosh, including the wider, flared tail at the back.
2. Keep your points minimal so the curve flows smoothly. Fewer points = easier edits.
3. Once the shape is drawn, double-click it to reveal the anchor points.
4. Adjust the handles of each anchor point to smooth out the curves and refine the motion of the swoosh until it feels clean and natural.

Step 3: Shape the star

1. Add a Polygon to the canvas and place it on the top right of your image.
2. In the right-hand panel, change it to 4 points to create a simple star shape.
3. Adjust the Curve slider until it feels balanced and matches the style of your swoosh.

Step 4: Add the punch-hole detail on the planet

1. Draw a small ellipse and place it on the mid-bottom side of the planet.
2. Select the small ellipse and the planet ellipse.
3. Click Exclude to carve out a clean punch-hole to give the planet a bit more character.

Step 5: Carve and position the orbit ring

1. Create the main ring: Start by drawing two ellipses: one large ellipse for the outer ring and a smaller ellipse inside it for the inner edge. Group these two shapes together. Set it aside. This grouped ring will remain untouched and will become your final orbit ring later.
2. Prepare a duplicate carving ring: Duplicate the main ring and place the duplicate above the planet layer. This copy will act as your cutter, so make sure its stroke width matches the carved opening you want in the planet.
3. Splice the cutter ring: Select the duplicate ring, choose the Eraser tool, and rasterize it. Erase the top portion of the ring, which is the part that should sit behind the planet, then click Done. Vectorize it again using one color to turn it back into a clean vector shape.
4. Carve the front opening into the planet: Select both the planet and the spliced cutter ring, then click Subtract in the Shape Builder panel. This cuts a clean slot into the planet where the front arc of the ring will pass through
5. Add the final ring: Place your original ring from step 1 back into position. This becomes the actual orbit ring in the design, with the front arc fitting neatly into the carved slot and the back arc sitting visually behind the planet.

Key takeaways from using Shape Builder for logo design

Shape Builder is designed to simplify the process. It turns scattered geometry into a unified, professional-looking mark without requiring complex techniques or advanced skills.

• Begin with simple geometric shapes such as circles, ellipses, and polygons to outline the overall silhouette.
  
• Use Union to merge shapes that should behave as one continuous form, including the comet swoosh or a manually built star.
  
• Apply Subtract one pair at a time to carve clean cutouts for the orbit ring. Clean overlaps produce clean results.
  
• Refine the final composition by adjusting scale, spacing, and proportions until everything feels intentional and balanced.
  
• Test your logo in monochrome to make sure it stays clear and readable at any size.
