Macro Unfold Box/fr

Description
La macro permet de déplier les surfaces d'un objet de n'importe quelle forme et la dessiner sur une page.



Installation
Copiez le fichier de la macro dans le répertoire :
 * Linux & Mac  : $home/.Freecad/Mod/unfoldBox.
 * Windows : C:\Program Files\FreeCAD0.13

Ajouter les templates : A3_Landscape_Empty.svg A3_Landscape.svg  A4_Landscape_Empty.svg  A4_Landscape.svg

Cf Macro for unfolding box surfaces

Forum topic: Macro for unfolding box surfaces.

Options

 * Échelle manuelle ou automatique
 * Format de Page : A3 / A4, cartouche (cf FreeCAD modèles)
 * Groupe les dessins dans la même page si possible.
 * Attache ou non les bords de la pièce.



Utilisation

 * 1) Sélectionnez un volume créé avec par exemple Part::Loft tool
 * 2) Développe la forme dans le plan de la forme (cf Draft menu)
 * 3) Sélectionnez la surface
 * 4) Exécuter la macro

The unfolding algorithm will place the faces on the XY plane, however it seldom does the unfolding correctly. Thus some manual post-processing is needed to get to desired result, as shown in the picture below.



Starting point is a box like the upper left picture.


 * 1) Select all faces and run the macro.
 * 2) Orient to Top View.
 * 3) Toggle the visibility on the created set of faces, the individual clones are to be visible, not the compound.
 * 4) Use Draft Move and Draft Rotate to reposition the unfolded cloned faces (a handful of clicks per face when snapping is used).
 * 5) The drawing updates automatically to the new positions.

The finished result is shown in the lower right picture above.

__doc__ = """ select a face, or several and run the macro. a shell/solid needs to be draft/downgraded to get the faces as separate objects

the macro is intended to unfold a set of planar faces, in current state, most of the times it does not place the faces correctly. thus one needs to do the final placement of the clones manually, with Draft/Move & Rotate regardless, the macro saves a lot of clicks compared to a fully manual unfold

settings are not context aware, all settings not applicable are ignored. as example, using autoscaling ignores the scale-value in the form

sew is always enabled, thus the drawing is always the sewed shape on a single page

v1.1  (2022-07-28) py3/qt5 compat, cosmetic code changes, minor code tweaks for evolved fc-api added option to skip drawing, made layout engine with techdraw, the drawing wb layout engine is now called "legacy" v1.0.1 (2020-03-10) - on wiki v1.0  (2013-09-14) - on wiki

note: - unfolding occasionally work as expected, but mostly not - anyone is free to improve functionality
