Select a 3D shape, adjust the dimensions using the input fields, and view the resulting net on the right panel. Rotate the 3D preview by dragging with your mouse. Click Download Net to save the pattern as a high-resolution PNG image, or use Print to print directly.

Yes! Click the Print button to open a print-ready view of the net. For best results, use thick paper (cardstock, 180-220 gsm) and ensure your printer settings are at 100% scale (no scaling/fit-to-page).

We recommend cardstock paper between 180 gsm and 220 gsm (65-80 lb cover). This weight is sturdy enough to hold the 3D shape yet flexible enough for clean folding. Lighter paper may tear; heavier paper may be difficult to fold precisely.

Glue tabs are small flaps added to some edges of the net. They provide extra surface area for applying glue when assembling the 3D shape, resulting in stronger and cleaner joints. Enable the Glue Tabs checkbox to add them to your net pattern.

A cube has 11 distinct nets (unfold patterns). Other shapes have fewer variants. This tool provides 2-3 of the most practical variants for each shape. Click the Variant button to cycle through available net layouts.

Colors help you identify corresponding faces between the 3D preview and the 2D net. Each face (Top, Bottom, Front, Back, Left, Right, or Side/Base for curved shapes) uses a consistent color in both views, making it easier to visualize how the net folds into the 3D shape.

Yes! For cylinders, the net includes a rectangular side (width = circumference) and two circular ends. For cones, the net includes a circular base and a扇形 (sector) for the lateral surface. The curved surfaces approximate smoothly when you roll the paper during assembly.
