Hi there.
SelectionCommandInput is used to create an add-in that appears pre-selected when the dialog is displayed.
I'm having trouble getting it to work the way I want it to, so if you know of a way to get around this, please let me know.
I have created a script to reproduce the behavior.
# Fusion360API Python script
import traceback
import adsk.fusion
import adsk.core
_app: adsk.core.Application = None
_ui: adsk.core.UserInterface = None
_handlers = []
_selIpt: adsk.core.SelectionCommandInput = None

def __init__(self):
super().__init__()
def notify(self, args: adsk.core.CommandCreatedEventArgs):
# adsk.core.Application.get().log(args.firingEvent.name)
try:
global _handlers
cmd: adsk.core.Command = adsk.core.Command.cast(args.command)
inputs: adsk.core.CommandInputs = cmd.commandInputs
onDestroy = MyCommandDestroyHandler()
cmd.destroy.add(onDestroy)
_handlers.append(onDestroy)
onExecute = MyExecuteHandler()
cmd.execute.add(onExecute)
_handlers.append(onExecute)
onActivate = MyActivateHandler()
cmd.activate.add(onActivate)
_handlers.append(onActivate)
global _selIpt
_selIpt = inputs.addSelectionInput(
'selIptId',
'sketch curves',
'select sketch curves'
)
_selIpt.setSelectionLimits(0)
_selIpt.addSelectionFilter(
adsk.core.SelectionCommandInput.SketchCurves
)
# Preselect sketch lines
global _app

P3D = adsk.core.Point3D
points =[
(P3D.create(1,0,0), P3D.create(1,2,0)),
(P3D.create(2,0,0), P3D.create(2,2,0)),
(P3D.create(3,0,0), P3D.create(3,2,0)),
(P3D.create(4,0,0), P3D.create(4,2,0)),

for p1, p2 in points:
sktLines.addByTwoPoints(p1, p2)
app.activeViewport.fit()
When I run it, it creates a sketch in a new document and draws 4 straight lines.
When the dialog appears, two of the lines are selected.
I was hoping that if I click on them, which are already selected, they will be deselected. However, the number of selections increases.
Furthermore, when the OK button is pressed in this state, the number of selections and the entityToken of the selected elements are output to the text command window, but duplicate entityTokens are output.
This is an example of the output.
selectionCount:3

I tried addSelection with the commandCreated and activate events, but they did not work as expected.
Does anyone know a good way to make addSelection deselect a selected element when it is clicked from the selected state and the dialog is displayed?
Please advise.
