Hallo Wilfried,

das Problem ist, dass ein Bauteil nicht immer nur eine Farbe hat. Hoffe das passt so.

Gruß Benjamin
Vielen lieben Dank Benjamin. Jetzt passt es soweit. Klasse Job!!! 8-)

Viele Grüße
Wilfried

Nachtrag, wenn man jetzt noch eine Datum-Plane oder Fläche wählen könnte, durch die der Schnitt läuft sowie die Richtung ggf. umkehren, dann wäre das Skript perfekt. Ich weiß, kleiner Finger ganze Hand ... :lol:

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Dialog creation. My macros on Gist.github.

Hey Jungs,

ich hatte leider wenig Zeit. Mario, danke für das updaten. Wilfried, ich schau mir das die Tage mal an. Die Richtung umkehren sollte nicht so schwierig sein.

Hallo zusammen!

Danke an die Entwickler für das Makro "Macro_cross_section".

Das Makro funktioniert bei mir gut, solang ich keine Baugruppe schneiden möchte, die constraints enthält. Sobald constraints anwensend sind, treten Fehler auf, siehe weiter unten.

Hier mein Vorgehen:
Zuerst habe ich zwei Bodies mit PartDesign erzeugt. BlockOhneZylinder.FCStd & BlockMitZylinder.FCStd Siehe Anhang.

Dann habe ich eine Baugruppe mit Assembly2 erstellt: BaugruppeMitConstraint.FCStd. Auch im Anhang. Durch diese möchte ich einen Schnitt erzeugen.

Mit Constraints ist das die Fehlerausgabe:
Traceback (most recent call last):
File "C:/Users/Rene/AppData/Roaming/FreeCAD/Macro/Macro_cross_section.FCMacro", line 577, in <module>
myWidget = CrossSectionWindow()
File "C:/Users/Rene/AppData/Roaming/FreeCAD/Macro/Macro_cross_section.FCMacro", line 109, in __init__
self.child.initUI(self)
File "C:/Users/Rene/AppData/Roaming/FreeCAD/Macro/Macro_cross_section.FCMacro", line 147, in initUI
self.hideObjects()
File "C:/Users/Rene/AppData/Roaming/FreeCAD/Macro/Macro_cross_section.FCMacro", line 363, in hideObjects
b = self.oblist.Shape.BoundBox
<type 'exceptions.AttributeError'>: 'FeaturePython' object has no attribute 'Shape'



Das Makro erstellt den Schnitt nur, wenn ich vorher alle Constraints lösche. Das ist nur meine Übungsbaugruppe für eine komplexere. Dort möchte ich eigentlich ungern jedes Mal alle Constraints manuell herauslöschen wenn ich einen neuen Schnitt erzeugen möchte.

Habt ihr Erklärungen? Mache ich einen Fehler?
Hilfe ist sehr willkommen! :lol:

Das Makro ist langsam ziemlich unübersichtlich. Der Ansatz DRY (Don't repeat yourself) fehlt gänzlich. Zudem gibt weitere Möglichkeiten wie Slice usw. Neutaufsetzung sollte folgen. Aber vorerst eine Lösung für dich:

Code: Select all

*   This widget makes an interactively moveable cross-section of the      *
*   currently visible objects in the currently active document. The       *
*   cross-sectioning plane is specified by its normal, and the cross-     *
*   section can be moved along that normal using a slider bar. It can     *
*   show the cross-section either as an outline or a view of the sliced   *
*   objects. To run the macro, first download it from this site and       *
*   install it in your macros directory, then use the menu to call up     *
*   your list of macros and double-click on this one. It will display     *
*   a default cross-section and pop up a window to enable you to set      *
*   the cross-sectioning parameters. Closing the pop-up window will       *
*   restore the scene to its previous state before the macro was          *
*   started.                                                              *
