Lo strumento <a href="https://www.freecadweb.org/wiki/index.php?title=Part_Section/it" title="Part Section/it">Part Sezione</a> produce dei bordi discontinui e gran numero di segmenti (nodi), e questo non è molto adatto per il percorso di <a href="https://www.freecadweb.org/wiki/index.php?title=Part_Sweep/it" title="Part Sweep/it">Sweep</a>.
|
|
</p><p>Questa macro fa la stessa cosa estraendo i bordi della sezione dal risultato di una fusione generale (GFA). Il risultato è più continuo e ha meno nodi. Non è ancora perfetto per lo sweep, ma il risultato è più soddisfacente che utilizzando semplicemente la Sezione di Part.
|
|
</p><p>Richiede FreeCAD v0.17+ built against OCC no less than 6.9.0 (testato con 7.0.0).

Macro Section.
|
|
Alternative implementation of Part Section tool.
|
|
Requires FreeCAD v0.17+ and OCC 6.9.0+
|
|
|
|
Instructions:
|
|
First of all, save this macro as MacroSection.py, into a location from where it can be imported. FC's standard macro location is the best place to do that.
|
|
|
|
Select two shapes to compute section between.
|
|
Then, in Py console:
|
|
|
|
import MacroSection
|
|
MacroSection.run()
|
|
|
|
OR
|
|
|
|
just run this file as a macro.
|
|
|
|
Parametric Section object is created.
