Hello, I'd like to enumerate through all layers, select all objects on a layer, then perform a custom function on the selected objects. I'm not able to identify if the objects i have selected are part of the active layer. i would expect it to work similar to this:

def selectObjinLayer():

    doc = Window.ActiveWindow.Document

 

    for layer in Layers.GetAllLayers():

        #print(layer.GetName())

        Layers.Activate(layer.GetName())

        selection = Selection.Clear()

        selection = Selection.Create(Layers.GetActive())

        secondarySelection = Selection.Empty()

        

        #this is the point where the script fails

        # the GetAllBodies returns empty, so no iteration occurs

        for design_body in doc.MainPart.GetAllBodies():

            print("check if ", design_body," is in layer ", layer)

#this is a nonsense getter and comparison:

           if design_body.Layer == layer:

                selection.AddToActive()

        return selection

 

selectedOBJS = selectObjinLayer()

customFunction(selectedOBJS)

 

the customFunction fills all objects, then renames the associated Surfaces based on the layer name.

Hi David,

Let me check and get back to you. 

Thanks and Regards

Hi Atharv,

Thanks for investigating this, I'm excited to see what you come up with.  

Perhaps this is helpful: when right-clicking on a layer, the "select all objects" function does exactly what I need, but the macro recorder cannot record its action.

BEst,

Dave

An Ansys engineer has helped me to close this issue. The resulting code is:

 

def fillSelected(layer_curves):
    #fill the curves in the layer. this creates a new surf body
    selection = Selection.Create(layer_curves)
    secondarySelection = Selection.Empty()
    options = FillOptions()
    result = Fill.Execute(selection, secondarySelection, options, FillMode.ThreeD)

allCurves = GetRootPart().GetDescendants[IDesignCurve]()
for layer in Layers.GetAllLayers():
    layer_curves=[i for i in allCurves if i.Layer==layer]
    if not len(layer_curves)==0:
        Layers.Activate(layer.GetName())
        fillSelected(layer_curves)
