Part__Feature_solid with the object name

[Oli772]

Hello,
I am doing a Part_BooleanFragments operation as below

Code: Select all

App.newDocument("Unnamed")
Gui.ActiveDocument.mergeProject("/home/.../part1.FCStd")
Gui.ActiveDocument.mergeProject("/home/.../part2.FCStd")
Gui.ActiveDocument.mergeProject("/home/.../part3.FCStd")

### Begin command Part_BooleanFragments
j = BOPTools.SplitFeatures.makeBooleanFragments(name='BooleanFragments')
j.Objects = [App.ActiveDocument.Part__Feature_solid, App.ActiveDocument.Part__Feature_solid001, App.ActiveDocument.Part__Feature_solid002]
j.Mode = 'Standard'
j.Proxy.execute(j)
j.purgeTouched()
for obj in j.ViewObject.Proxy.claimChildren():
    obj.ViewObject.hide()
### End command Part_BooleanFragments

Howeve I would like, in the "j.Objects" command, to replace the name "Part__Feature_solid" with something linked to the true name of the part, "part1" in that case
So the command would be

Code: Select all

j.Objects = [App.ActiveDocument."something...part1", App.ActiveDocument."something...part2", App.ActiveDocument."something...part3"]

How can I do that ?
Thanks
Oli

I'm sure there's a more efficient way but this is the best I could come up with:

Code: Select all

App.newDocument("Unnamed")
Gui.ActiveDocument.mergeProject("/home/.../Part1.FCStd")
objs = FreeCAD.ActiveDocument.Objects
for obj in objs:
    sPart1 = obj
Gui.ActiveDocument.mergeProject("/home/.../Part2.FCStd")
objs = FreeCAD.ActiveDocument.Objects
for obj in objs:
    if obj != sPart1:
        sPart2 = obj
        break
Gui.ActiveDocument.mergeProject("/home/.../Part3.FCStd")
objs = FreeCAD.ActiveDocument.Objects
for obj in objs:
    if obj != sPart1 and obj != sPart2:
        sPart3 = obj
        break

### Begin command Part_BooleanFragments
import BOPTools.SplitFeatures
j = BOPTools.SplitFeatures.makeBooleanFragments(name='BooleanFragments')
j.Objects = [sPart1, sPart2, sPart3]
j.Mode = 'Standard'
j.Proxy.execute(j)
j.purgeTouched()
for obj in j.ViewObject.Proxy.claimChildren():
    obj.ViewObject.hide()
### End command Part_BooleanFragments
Gui.SendMsgToActiveView("ViewFit")

Tested using:

thank you Syres.

This should solve part of my issue which is to keep and bring the names of the booleans fragments from this FC brep file through the geometry import process of Gmsh. That is obviously another story but it seems that Gmsh does not recognize at all the naming and the order in which they have been made.. the import gives there a random surface numbering
