The "execute()" function is ignored

[SaeedHamza]

Hi,

I'm trying to make a script to scale a body using a custom axis.

The idea is to align the body to one of the 3 axes, scale it and then return it to its proper position.

Now since the align tool isn't accessible through the API object model, I used this method below that I saw @BrianEkins used in this post : API access to Align Components Function - Autodesk Community - Fusion 360

        ui.activeSelections.clear
        ui.activeSelections.add(alignment_edge)
        ui.activeSelections.add(rootComp.xConstructionAxis)
       
        alignCommand = ui.commandDefinitions.itemById('AlignGeometryCmd')
        alignCommand.execute()

It works like a charm when it's alone, but the moment I make something else it gets ignored, for example, when I try to scale after the alignment, the script only applies the scale in the original position of the body, without the alignment even showing in the timeline ...

I even tried to just create a sketch on the xy plane from the root component, as a completely separate action after the alignment, and the same thing happened, the sketch was created but the alignment was ignored.

Moreover, I even tried the "transaction.Commit" after the alignment to force Fusion to apply it, but no use ...

Any ideas why this is happening???

Thanks in advance.

Here is my code :

import tempfile
import adsk.core, adsk.fusion, adsk.cam, traceback

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui  = app.userInterface
        
        design = adsk.fusion.Design.cast(app.activeProduct)

        rootComp = design.rootComponent
        features = rootComp.features
        scales = features.scaleFeatures

        alignment_edge_sele = ui.selectEntity('Select BRepEdge entities of any shape', 'Edges')
        alignment_edge = alignment_edge_sele.entity

        ui.activeSelections.clear
        ui.activeSelections.add(alignment_edge)
        ui.activeSelections.add(rootComp.xConstructionAxis)

        app.executeTextCommand('Transaction.Start Saeed')

        alignCommand = ui.commandDefinitions.itemById('AlignGeometryCmd')
        alignCommand.execute()

        app.executeTextCommand('Transaction.Commit')

        xScale = adsk.core.ValueInput.createByReal(0.5)
        yScale = adsk.core.ValueInput.createByReal(1.00)
        zScale = adsk.core.ValueInput.createByReal(1.00)

        point = alignment_edge.startVertex
        objcol = adsk.core.ObjectCollection.create()
        objcol.add(alignment_edge.body)
        factor = adsk.core.ValueInput.createByReal(1.00)
        scale_input = scales.createInput(objcol, point, factor)
        scale_input.setToNonUniform(xScale, yScale, zScale)

        scales.add(scale_input)

    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Hi @SaeedHamza .

Since the commandDefinition.execute method is processed together at the end of the script, it will not be executed at the intended timing even if you try to execute it in the middle of the script.

Instead, this would give the desired result.

・・・
        ui.activeSelections.add(rootComp.xConstructionAxis)

        # app.executeTextCommand('Transaction.Start Saeed')

        # alignCommand = ui.commandDefinitions.itemById('AlignGeometryCmd')
        # alignCommand.execute()
        app.executeTextCommand('Commands.Start AlignGeometryCmd')

        # app.executeTextCommand('Transaction.Commit')

        xScale = adsk.core.ValueInput.createByReal(0.5)
・・・

thank you @kandennti, this is exactly what I needed.

But does this mean that it has to be through using text commands when executing a native F360 command?

[SaeedHamza]

I finished the code, so I thought might as well share it

Thanks for the help @kandennti 

One thing that annoyed me is that the script needs 2 selections, a reference (stationary) point, and an edge as the custom axis, and when the point selection comes after the edge selection, it won't be cleared ...

So I guess the last entity selected can't be cleared from the active selections, that's where the "activeSelections.clear" fails.

That was solved basically by making the script select the point first and then the edge.
