Button for Sketch.ShowUnderConstrained

[christopher_hermansson]

Hi! I want to make an add-in that places a button on the sketch toolbar that runs the command Sketch.ShowUnderConstrained when clicked. I've been trying for several hours, with the help of Chat-GPT, with no real success. Is it even possible?

Hi @christopher_hermansson -San.

The following sample switches between Driving/Driven dimensions.
It should be performed in the edit state of the sketch.

# Fusion360API Python script

import traceback
import adsk.core as core
import adsk.fusion as fusion

def run(context):
    ui: core.UserInterface = None
    try:
        app: core.Application = core.Application.get()
        ui = app.userInterface
        des: fusion.Design = app.activeProduct

        skt: fusion.Sketch = fusion.Sketch.cast(des.activeEditObject)
        if not skt: return

        dim : fusion.SketchDimension = None
        for dim in skt.sketchDimensions:
            dim.isDriving = not dim.isDriving

        ui.messageBox("Done")

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

Sorry, I made a mistake.

In the following sample, you can toggle the "Show Constraints" on the screen.

# Fusion360API Python script

import traceback
import adsk.core as core
import adsk.fusion as fusion

def run(context):
    ui: core.UserInterface = None
    try:
        app: core.Application = core.Application.get()
        ui = app.userInterface
        des: fusion.Design = app.activeProduct

        skt: fusion.Sketch = fusion.Sketch.cast(des.activeEditObject)
        if not skt: return

        skt.areConstraintsShown = not skt.areConstraintsShown

        ui.messageBox("Done")

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

However, the Sketch Palette check was not linked.

Therefore, I modified it and used the text command.

・・・
        # skt.areConstraintsShown = not skt.areConstraintsShown
        txtCmd = u'Commands.SetBool show_constraints {}'.format(
            0 if skt.areConstraintsShown else 1
        )
        app.executeTextCommand(txtCmd)
・・・

Thank you, but that wasn't really what I was asking about. There is a text command "Sketch.ShowUnderConstrained" that you can type into the text command prompt. I just want to add a button to the toolbar that executes that command.

Sorry, I misunderstood again.

The only way to add a button to the menu is to create an add-in.

We do not use that text command, but we have created an add-in that does something similar.

There are several commands, but the "SketchAnalysis" command does the same thing.

However, they are all displayed in Japanese. If necessary, we will modify it so that it can be displayed in English as well.

Fantastic!

The display has been modified to switch according to the language of preferences.
