Work Feature workbench with parametric objects

[rentlau_64]

Hello all

I need Help to find a manner to reference my "CenterLinePoint" Object to a "BaseFeature" (if selected)

my code is :

Code: Select all

class CenterLinePoint(WF_Point):
    """ The CenterLinePoint feature object. """
    # this method is mandatory
    def __init__(self,selfobj):
        self.name = "CenterLinePoint"
        WF_Point.__init__(self, selfobj, self.name)
        """ Add some custom properties to our CenterLinePoint feature object. """
        selfobj.addProperty("App::PropertyLinkSub","Edge",self.name,
                            "Input edge")   
        selfobj.addProperty("App::PropertyInteger","NumberLinePart",self.name,
                            "The number of parts of parent segment !").NumberLinePart=2
        selfobj.addProperty("App::PropertyInteger","IndexPart",self.name,
                            "The location of the point : 1/2 means middle of the segment !").IndexPart=1        
        
        selfobj.setEditorMode("Edge", 1)
        selfobj.Proxy = self    
     
    # this method is mandatory   
    def execute(self,selfobj):
    	...

And I get an error : "Link go out of the allowed scope" for the "CenterLinePoint" Object created.

Hereafter an illustration

Assuming you are not creating any cyclic references, simply change your PropertyLinkSub to PropertyLinkSubGlobal shall work. The reason for this message is because Body, being derived from geo feature group, demands all objects that reference its children being added to the group, too. So, by right, your CenterLinePoint object should be added to the Body (or App::Part) as well. You can use Global links to bypass that requirement.

On the other hand, you should realize that if you link to a children of a body without adding your object to the body as well, you'll have trouble getting the actual coordinate of the object.

Hi,

A new release is on line...

Thank very much you I will use this info for next release.

Hello,
Is there any value to add this workbench to /FreeCAD-addons ?

If yes feel free to do, i will be very please.

Is it supposed to work in .17 now.. here still no luck.. cannot refer to the created elements, They are not in the active body, nor can i move them into it...

I installed and see only this:

Should I be seeing all the FUNCTIONs of the old WF-macro ?
Selecting in the WB-mode will be nicer than the cramped panel-mode!

I am using FC-Daily: Git version 13375; just FYI!

Great. Note that is could take a few days.

Likely this wasn't tackled yet in Work Feature workbench. In addition i feel that some general guidelines or/and discussion about this area is still missing and will need to happen in the future.

Should I be seeing all the FUNCTIONs of the old WF-macro ?

I bit of patience will likely be needed to get to that goal.

Selecting in the WB-mode will be nicer than the cramped panel-mode!

Both approaches have some pros and cons. Workbench approach for example should for one improve the customization potential. More standard workflow and install and usage experience is expected too. Parametric objects ...
