You can start from included models.
With 70+ included models, the first step is easy. Open a model, print it, assemble it, and understand how the shapes become paper models.
SHIRYU lets you design a simple 3D model, unfold it into printable patterns, and assemble it as a paper model.
It also includes 70+ ready-to-build models, so you can start by printing and assembling existing models, then use them as references for your own designs.
SHIRYU is not just a collection of finished patterns. Its value is that you can move from ready-made examples to designing paper models yourself, then print and build the result.
Ready-made unfolded patterns are useful, but they end at one finished design. SHIRYU gives you a way to design a paper model on screen, unfold it, print it, and assemble it.
With 70+ included models, the first step is easy. Open a model, print it, assemble it, and understand how the shapes become paper models.
This is the core of SHIRYU. It is not limited to pre-made content. You can create and edit shapes, then unfold them into printable patterns.
The interface is intentionally simple, so the workflow can stay close to the goal: design a shape, unfold it, print it, and build a paper model.
SHIRYU does not stop at the screen. The goal is a real paper model you can print, cut, fold, and assemble.
The workflow is direct. Start from an included model, or start from a shape you design on screen.
Open an included model and modify it, or begin from scratch. This is where the paper model starts.
Turn the shape into printable unfolded patterns. This is the bridge from screen design to paper model.
It does not stay digital. In the end, you get a paper model that can be held, displayed, and learned from.

SHIRYU has been improved little by little over time. It can be used as a papercraft tool, a classroom aid, or a small creative environment for paper models.
This should be stated clearly: SHIRYU is a Windows-only desktop software. It is not a phone app.
