Add children to parent object

[dubstar-04]

I would like to create an object:

Code: Select all

obj_chassis = doc.addObject("App::FeaturePython","Chassis")

and then add child object to it.

I have had a quick look at the arch workbench to see how its done but i don't really understand it. Can anyone advise?

Thanks,

Dan

Hi Dan,

Here is an example of how we have been doing it in the Path workbench (a work in progress that isn't in master yet):

https://github.com/danielfalck/FreeCAD/ ... re.py#L138

We are inserting the new object into the parent object's 'group' . This example is a specialized case of adding a CNC fixture offset object into the CNC project object. The way I am doing it there - the for loop and all that - is just to find the parent object in the Document tree. You can insert something into a group directly, if you already know it's Name.
I hope that helps a bit.

Thanks for the reply.

I have the following code working now.

Code: Select all

        doc = FreeCAD.activeDocument()
        obj_chassis_project = doc.addObject("App::DocumentObjectGroupPython","Chassis Project")
        obj_chassis_child = doc.addObject("App::FeaturePython","Chassis")         
        Chassis(obj_chassis_child)
        g = obj_chassis.Group
        g.append(obj_chassis_child)
        obj_chassis.Group = g

Thanks,

Dan
