OrigamiDraw

Copy, Paste, and Mirror-Paste, within a CP or from one CP to another. This allows all kinds of manipulations, like re-using part of a design, completing a symmetrical CP or a tiling, or designing a tilted-grid model.

- Long-press replaces press-and-drag as it is the new standard across all iOS and iPadOS devices. - New functions to draw folds at multiples of 22.5, 30, or 15 degrees (see in the “perpendicular” submenu). - Export to CP format (for import into Orihime). - Improved zooming, increased grid sizes (256 on iPad, 128 on iPhone). - Big-Little-Big Lemma of flat-foldability. - X-ray image included in JPEG, PNG, and SVG exports. - Refreshed button designs.

- Search in the CP Catalog. - Virtual folding! If flat-foldability theorems are satisfied, an X-ray view of your model can be shown on top of your CP, with one face shared between them. You can move this shared face anywhere on your CP. You can revert to normal drawing mode leaving the X-ray view in place as a reference, or dismiss it. If some theorems are not satisfied, symbols will show as before where the problems are. If only Maekawa's 2nd theorem (color assignment) is not satisfied, you can still get the X-ray view, meaning you can get the folded view of a non-oriented CP. - Parallel and Axioms 5, 6, and 7 work in more edge cases.

Extension of some features to make them more intuitive and powerful: - The order of entry for the Mirror function has been changed from Fold-Mirror to Mirror-Fold. Sorry to make you change your habits but it opens up new possibilities! - Angle Bisection and Mirror Fold now work with parallel folds. - More export options have been added: PNG, JPG, and SVG (with different color schemes). - Links to an online Tutorial and a Privacy Policy (see Settings).

Origami Draw is now more powerful and easier to use than ever. It has become the first app that implements all 7 axioms of origami folding! (i.e., Huzita-Hatori/Justin axioms.) You can draw the most complex geometries without any calculation. Moreover, with the new Grid menu, you can vary the display according to your needs: with or without the grid, reference lines, or vertices, so you can keep your focus on the structure of your origami, with nothing to distract you.

Fixed a bug in function "Fold a Point Onto a Line, Around a Pivot" that was giving the wrong fold in some particular situations. In the process, the entry mode was changed from point-line-pivot to pivot-point-line. This allows selection of the desired fold when two possibilities exist. When the fold is entered, the landing point of the first point onto the line is also entered. It is invisible but can be selected for further constructions. This function is seldom used, except at the beginning of very technical designs. It is the Huzita-Hatori/Justin axiom #5.
