Sovrapposizione Booleana costruisce una forma che copre lo spazio occupato da non meno del 'OverlapIndex' forme. 'OverlapIndex' è una proprietà che può essere modificata. Il valore 1 fornisce il risultato equivalente a Part Unione. Il valore pari al numero di forme rende lo strumento equivalente a Part Intersezione. Il valore predefinito è 2, vale a dire il risultato riempie lo spazio in cui non vi è alcuna sovrapposizione.
Richiede FreeCAD v0.17+ costruito su OCC non inferiore a 6.9.0 (provato con 7.0.0).
Installazione
Scaricare il file MacroOverlap.py e salvarlo nella directory delle macro:
https://github.com/DeepSOIC/FreeCAD-Macros/raw/master/Overlap/MacroOverlap.py
Uso
- Selezionare tre forme* o più per calcolare sovrapposizione tra loro. È anche possibile selezionare un singolo composto contenente le forme.
- In FreeCAD menu: Macro → Macros... → doppio-click su MacroOverlap.py. Viene creato un nuovo oggetto.
- Selezionare il nuovo oggetto, e se necessario modificare la proprietà 'Overlap Index' nella scheda Dati
* si può fare anche due forme, ma l'azione dello strumento è equivalente a Part Intersezione or Part Unione, e quindi si consiglia di utilizzare gli strumenti di Part.

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.
