Can't clear the activeSelections

I want to clear the activeSelections, but if they are selected using userInterface.selectEntity, they will not be cleared.

import adsk.core, adsk.fusion, traceback

_app = adsk.core.Application.cast(None)
_ui = adsk.core.UserInterface.cast(None)

def run(context):
    try:
        global _app, _ui
        _app = adsk.core.Application.get()
        _ui = _app.userInterface

        msg :str = 'select SolidBody'
        selFiltter :str = 'SolidBodies'
        _ui.selectEntity(msg, selFiltter)

        actSels = _ui.activeSelections
        _ui.messageBox('Before clearing count : {}'.format(actSels.count))

        actSels.clear()
        _ui.messageBox('After clearing count : {}'.format(actSels.count))

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

As far as I remember, I was able to clear it.
I'm using Fusion360 Ver 2.0.8749.

@kandennti  I am not able to reproduce it. Not sure what is going wrong on your side. Thanks.

Thanks @goyals .

 

I expect activeSelections.count after ui.activeSelections.clear() to be "0".

I can reproduce it.  I'm a bit surprised that the selectEntity method is adding the entity to the active selection.  But since it appears that's what is happening you would expect the clear to remove it.  I'll work with Shyam to log this.

Thanks @BrianEkins.

 

I couldn't see any other possibilities for deselecting the selection state other than this.

 

As described by @Duracellman425 here

https://forums.autodesk.com/t5/fusion-360-api-and-scripts/selectentity-causes-fusion-to-crash/m-p/96... 

I'm wondering if this is due to the addition of "activeSelectionEvent".

 

I've confirmed that the event is fired when selecting with selectEntity and not when using the clear method.
(Since it is not cleared, I think you are correct that the event is not fired.)

Does it work if you use e. g. removeByIndex ()?

Thanks @thomasa88 .

 

I tried "removeByIndex", "removeByEntity" and "removeBySelection" with the same result.

I can clear the selections.add.

・・・
        _ui.messageBox('Before clearing count : {}'.format(actSels.count))

        # actSels.clear()
        # actSels.removeByIndex(0)
        # actSels.removeByEntity(actSels.item(0).entity)
        actSels.removeBySelection(actSels.item(0))
        _ui.messageBox('After clearing count : {}'.format(actSels.count))

        des :adsk.fusion.Design = _app.activeProduct
        root :adsk.fusion.Component = des.rootComponent
        _ui.activeSelections.add(root.xYConstructionPlane)
        _ui.messageBox('add xyPlane count : {}'.format(actSels.count))

        actSels.clear()
        _ui.messageBox('clearing again count : {}'.format(actSels.count))

I'm pretty sure this change is now crashing my add-in. Any command that uses selectEntity, then passes that entity to a native Fusion command crashes to CER.

I tried various things I could think of.

# Fusion360 ver2.0.9313
import adsk.core, adsk.fusion, traceback

_app = adsk.core.Application.cast(None)
_ui = adsk.core.UserInterface.cast(None)

def run(context):
    try:
        global _app, _ui
        _app = adsk.core.Application.get()
        _ui = _app.userInterface

        msg :str = 'select SolidBody'
        selFiltter :str = 'SolidBodies'
        sel = _ui.selectEntity(msg, selFiltter)

        actSels = _ui.activeSelections
        dumpMsg('Before clearing count : {}'.format(actSels.count))

        # NG
        actSels.clear()
        dumpMsg('After clearing count(Selections.clear Method) : {}'.format(actSels.count))

        # NG
        _app.executeTextCommand(u'Selections.Clear')
        dumpMsg('After clearing count(TextCommands-Selections.Clear) : {}'.format(actSels.count))

        # NG
        _app.executeTextCommand(u'PSelections.Clear')
        dumpMsg('After clearing count(TextCommands-PSelections.Clear) : {}'.format(actSels.count))

        # NG
        _app.executeTextCommand(u'Selector.Clear')
        dumpMsg('After clearing count(TextCommands-Selector.Clear) : {}'.format(actSels.count))

        # NG
        id = _app.executeTextCommand(u'Selections.List').rstrip('\n\r')
        _app.executeTextCommand(u'Selections.Add {}'.format(id))
        _app.executeTextCommand(u'Selections.Clear')
        dumpMsg('After clearing count(TextCommands-Reselect by entityID and Clear) : {}'.format(actSels.count))

        # OK
        ent = sel.entity
        _app.executeTextCommand(u'Commands.Start SelectabilityToggleCmd')
        actSels.add(ent)
        _app.executeTextCommand(u'Commands.Start SelectabilityToggleCmd')
        actSels.clear()
        dumpMsg('After clearing count(SelectabilityToggle) : {}'.format(actSels.count))

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

def dumpMsg(msg :str):
    _ui.palettes.itemById('TextCommands').writeText(str(msg))

 

By switching the Selectability, I was able to force the selection to be cleared, but it is cumbersome.

I've been having a hard time with this too ...

is it still not solved?

@SaeedHamza .

 

I still could not deselect when using the selectEntity method.

Therefore, it seems that the only way to do this is to use the above method.
