Strict geometry can feel cold. Curves and rounded corners add warmth - think app icons, wellness brands, and playful mascots. Logo Lattice gives you two ways to introduce curvature: arc segments between two points, and fillets on polygon corners.
Add arc segments
- Press 4 to activate the Curve tool.
- Click a start point, then drag to an end point - Logo Lattice draws a smooth arc between them.
- Toggle fill on the arc to colour the patch between the chord and the curve, useful for leaf shapes and smile curves.
Round polygon corners
Draw a polygon or drop a preset shape, then select it with the Select tool (2). Drag the small handles at each corner to set a fillet radius. You can also set a default radius in the function bar and apply one value to every corner at once - handy for uniform rounding on a hexagon or star.
Mix curves with straight edges
A strong organic logo often pairs one curved edge with several straight ones. Draw the straight skeleton with the polygon tool, then add a single arc segment for the distinctive curve. Keep the rest of the silhouette angular so the curve stands out.
Colour and export
Curved logos often use a single saturated fill with no stroke. Use the SVG tab in Export for smooth arcs at any scale, or PNG with a brand-fill background from the PNG tab if you want a coloured tile behind the mark.
