Summary0003351: Automated part to techdraw drawing script (python) crashes freecad at completition
DescriptionA python script that automatically draws a tech-draw drawing for each part in document makes freecad crash every time.
Steps To ReproduceThis script generates some random boxes and then generates a tech-draw page and view for each one of them, modifying some parameters like direction of projection and some fields of the template (part name and some specifications, just text)

Run by copy-paste on python terminal inside freecad:

import time
import FreeCADGui
from operator import itemgetter
import random

base_name = "EDCPI_"
drawing_revision = 'R0'
author_name = "JMG"
max_label = 50
current_label = 0

# create new document
FreeCAD.newDocument("Unnamed")
FreeCAD.setActiveDocument("Unnamed")
FreeCAD.ActiveDocument=App.getDocument("Unnamed")
FreeCAD.Gui.ActiveDocument=Gui.getDocument("Unnamed")

# create dummy objects
for i in range(max_label):
    obj = FreeCAD.ActiveDocument.addObject("Part::Feature", base_name + str(current_label))
    
obj.Shape = Part.makeBox(random.randint(5,30),random.randint(5,30),random.randint(5,30) )
    obj.Placement.Base.x = random.randint( -100, 100 )
    obj.Placement.Base.y = random.randint( -100, 100 )
    obj.Placement.Base.z = random.randint( -100, 100 )
    current_label += 1


current_label = 0

def doDrawingForLabel(label):
    current_label = label
    for obj in FreeCAD.ActiveDocument.Objects:
        try:
            if int( obj.Label[len(base_name):] ) == current_label:
                if obj.Shape.Volume != 0:  #check for solid
                    # create and setup page
                    draw_page = FreeCAD.ActiveDocument.addObject("TechDraw::DrawPage", obj.Label 
)
                    # TODO TEMPLATE IN DEPENDENCE OF BOUND BOX
                    # adjust templat
                    template = FreeCAD.ActiveDocument.addObject( 'TechDraw::DrawSVGTemplate', 'Template')

                    template.setEditFieldContent("DRAWING_TITLE", obj.Label )
                    template.setEditFieldContent("AUTHOR_NAME", author_name )
                    template.setEditFieldContent("FC-SC", "1:1")
                    template.setEditFieldContent("PN", obj.Label )
                    template.setEditFieldContent("FC-SH", str(current_label ) + " / "

This problem seems to have been fixed. I can run the script up to 75 pages without a crash on FC daily without a crash. The last ten pages are definitely slower to build than the first 10, but it doesn't crash.

I'm going to close this issue. We can reopen the ticket if the problem shows up again.
