== Utilizzo == |
|||
# Macro unfoldBox |
|||
# Selezionare un oggetto creato con Part, ad es. un oggetto creato con Loft. |
|||
# Unroll of a ruled surface |
|||
# Scomporre l'oggetto (utilizzare Draft -> Retrocedere) |

# Selezionare le supefici |

fields_l = [] |
|||
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. |
|||
unroll_l = [] |
|||
[[File:MacroUnFoldBoxInstruction.png|Macro_unfoldBox]] |
|||
Starting point is a box like the upper left picture. |
|||
# Select all faces and run the macro. |
|||
# Orient to Top View. |
|||
# Toggle the visibility on the created set of faces, the individual clones are to be visible, not the compound. |
|||
# Use [[Draft_Move|Draft Move]] and [[Draft_Rotate|Draft Rotate]] to reposition the unfolded cloned faces (a handful of clicks per face when snapping is used). |
|||
# The drawing updates automatically to the new positions. |
|||
The finished result is shown in the lower right picture above. |

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" |

Description
Descrizione
Questa macro permette di creare lo sviluppo delle superfici di un solido con facce piane, di disegnare le facce in una pagina e di inserire il disegno in un foglio A3 o A4.
Installation
Installazione
Secondo quanto descritto in Macro for unfolding box surfaces
Copiare il file del codice nella directory:
- Linux & Mac : $home/.Freecad/Mod/unfoldBox.
- Windows : C:\Program Files\FreeCAD0.13
Aggiungere i modelli del foglio : A3_Landscape_Empty.svg A3_Landscape.svg A4_Landscape_Empty.svg A4_Landscape.svg
Forum topic: Macro for unfolding box surfaces.
Options
Opzioni
- Scala manuale o automatica
- Formato della pagina: A3, A4
- Tabella (secondo i modelli di FreeCAD)
- Raggruppamento dei disegni nella stessa pagina se è possibile.
- Unire le facce su un lato.
Usage
Utilizzo
- Selezionare un oggetto creato con Part, ad es. un oggetto creato con Loft.
- Scomporre l'oggetto (utilizzare Draft -> Retrocedere)
- Selezionare le supefici
- Eseguire 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.
- Select all faces and run the macro.
- Orient to Top View.
- Toggle the visibility on the created set of faces, the individual clones are to be visible, not the compound.
- Use Draft Move and Draft Rotate to reposition the unfolded cloned faces (a handful of clicks per face when snapping is used).
- The drawing updates automatically to the new positions.
The finished result is shown in the lower right picture above.
