Boolean Overlap construit une forme qui couvre l'espace occupé par des formes superposées. 'OverlapIndex' est une propriété qui peut être modifiée. La valeur 1 donne le même résultat que Part Union. Une valeur égale au nombre de formes rend l'outil équivalent à Part Intersection. La valeur par défaut est 2, ce qui signifie que le résultat va utiliser l'espace où il y a chevauchement.
Require FreeCAD v0.17+ built against OCC no less than 6.9.0 (tested on 7.0.0).
Installation:
téléchargez MacroOverlap.py et sauvez la dans votre répertoires de macros:
https://github.com/DeepSOIC/FreeCAD-Macros/raw/master/Overlap/MacroOverlap.py
Utilisation:
- Sélectionnez trois ou plus d'objets pour créer un objet superposé. Vous pouvez aussi sélectionner un composé contenant plusieurs shapes.
- Dans le menu: Macro → Macros... → double-cliquez sur Overlap.FCMacro . Un nouveau objet est créé.
- Sélectionnez le nouvel objet, et modifiez les propriétés de 'Overlap Index' dans "Vue combinée → Propriétés onglet (Data)", si nécessaire.
* deux formes feront également l'affaire, mais l'action de l'outil sera équivalente à Part Intersection ou Part Union et il est donc recommandé d'utiliser les outils Part à la place.

Macro Overlap.
Requires FreeCAD v0.17.8053+ and OCC 6.9.0+
Instructions:
Select three or more shapes to compute Overlap between. A single compound will do, too.
Then, run this macro. Parametric Overlap object is created.
