Lic is a cross-platform, Python, OpenGL & Qt powered desktop application for creating and editing instruction books. Lic imports 3D models, organizes them into submodels, pages & steps, and exports the end result as images or PDF.

Highlights:

• A rich, WYSIWYG UI editor, which provides a fully interactive preview window along side a drag & drop-enabled navigation tree, to help organize and layout your book.

• Automatically divide your model into steps. Add a list of parts needed for each step, and auto-layout multiple steps per page for a best fit. Auto-generate a title page and part list pages.

So far, Lic can import any LDraw model, but its dynamic importer makes it easy to add an importer for any 3D file type, and create instructions for that model. A Lego Digital Designer (LDD) importer is coming soon.

When you're done, Lic can export a final instruction book as a series of images or as a high resolution PDF.

Lic is currently in a late alpha stage, and is improving very quickly. Check out the Lic home page for screen shots and more info.

There's windows and OSX binary packages available for download; this version has been tested against a handful of machines & video cards, and works well, but does require newer hardware. Let me know if you have any problems - I'm interested in trying to support older hardware, but have nothing to test against.
