Name of a solid in a compound - from selection

[mario52]

hi
ok this is the object type internal, not name

here other info by object

Code: Select all

# -*- coding: utf-8 -*-
#liste les objets du projet en cours

import os, ImportGui
import FreeCAD
from Draft import *

doc = FreeCAD.ActiveDocument
App.Console.PrintMessage("Document Name : " + str(doc.Name) + "\n")
objs = FreeCAD.ActiveDocument.Objects

print objs
i = 0
for obj in objs:
    i += 1
    print "___ Object num : ",i," ______________________________________________________"
    App.Console.PrintMessage("Type     : " + str(obj) + "\n")        
    App.Console.PrintMessage("TypeId   : " + str(obj.TypeId) + "\n")        
    App.Console.PrintMessage("Object   : " + str(obj.Shape) + "\n")
    App.Console.PrintMessage("Name     : " + str(obj.Name) + "\n")
    App.Console.PrintMessage("RealName : " + str(getRealName(obj.Name)) + "\n")
    App.Console.PrintMessage("Label    : " + str(obj.Label) + "\n")

The question left is how did bernd the trick in FEM-wb mesh-Groups (e.g. selectionParser in _TaskPanelFemMeshGroup.py)?
I did study his code a bit but could not find the final clue.

hi
extract to _TaskPanelFemMeshGroup.py

Code: Select all

selection  = FreeCADGui.Selection.getSelection()
print('selection element changed to Solid: ', selection[0].Shape.ShapeType, '  ', selection[0].Name)

for i, s in enumerate(selection[0].Shape.Solids):
    for e in s.Edges:
        print e
print
for i, s in enumerate(selection[0].Shape.Solids):
    for e in s.Faces:
        print e

Hi mario,

This 'only' lists only all Edges and Fases of all Solids. It does not give a clue how the Solids 's' are named.

Code: Select all

>>> selection  = FreeCADGui.Selection.getSelection()
>>> print('selection element changed to Solid: ', selection[0].Shape.ShapeType, '  ', selection[0].Name)
('selection element changed to Solid: ', 'Compound', '  ', 'BooleanFragments')
>>> 
>>> for i, s in enumerate(selection[0].Shape.Solids):
...     for e in s.Edges:
...         print e

ps.: I removed the single print in the middle without output.

I haven't had the time to read all, will do this later on the weekend. But this may help ... viewtopic.php?f=10&t=18937

I also included a min. .fcstd ...

with your file ...

The name of Solid[0] is Solid1 same name system as for Vertexes, Edges and Faces! The problem is how to get the solid, becaus getElement does not return the solid (see my last post), thus I implemented some own get_element in FemMeshTools which returns solids too.

Code: Select all

# App.ActiveDocument.Fusion.Shape.Solids[0] --> 'Solid1' of Fusion

import FemMeshTools
FemMeshTools.get_element(App.ActiveDocument.Fusion, 'Solid1')

App.ActiveDocument.Fusion.Shape.Solids[0].isSame(FemMeshTools.get_element(App.ActiveDocument.Fusion, 'Solid1'))

output:

Code: Select all

>>>
>>> # App.ActiveDocument.Fusion.Shape.Solids[0] --> 'Solid1' of Fusion
>>> 
>>> import FemMeshTools
>>> FemMeshTools.get_element(App.ActiveDocument.Fusion, 'Solid1')
<Solid object at 0x31fb4a0>
>>> 
>>> App.ActiveDocument.Fusion.Shape.Solids[0].isSame(FemMeshTools.get_element(App.ActiveDocument.Fusion, 'Solid1'))
True

Hi Bernd,
So you search through all solids in Fusion and look for the generic names 'Solid1', 'Solid2', ... ?
I don't like it... but if this is the only solution than I take it .

I might have not 100% understood what exactly your problem is about.

To select an solid out of an CompSolid or an Compound I activate a solid selection mode. In this mode the user has to select an edge or vertex which only belongs to one solid. Thus the solid is found. The reason is, there is no solid selection mode in FreeCAD selection system. See post viewtopic.php?f=10&t=18937#p147550 To save the solid in the reference shape list for later use I use the position in the solids list of the shape. Solids[0] is 'Solid1', Solids[1] is 'Solid2'

Just realized the system might not work if a solid is inside another solid, because all elements of the inner solid belong to the outer solid too. I need to try this on the mesh region object.

[DeepSOIC]

Just realized the system might not work if a solid is inside another solid, because all elements of the inner solid belong to the outer solid too.

Then I can suggest this approach: "if in doubt, choose one with the smaller volume".

Good idea, but could return the wrong one, because the inner could have less volume than the outer (the outer solid has not the volume of the inner, in case of a CompSolid). The bbox might be better approach. I really need to test ...
