Button for Sketch.ShowUnderConstrained

christopher_hermansson — Thu, 29 Jun 2023 17:14:46 GMT

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()))

@christopher_hermansson -San.

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.

@christopher_hermansson -San.

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.

@christopher_hermansson -San.

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

Please let me know and I will fix it.

I think it's a shame that such an important command is not offered in the Sketcher. I had a lot of fun with the Sketcher from the beginning, but I was always afraid of finding a missing Constrain. It was just too much of a relief when I found the command "Sketch.ShowUnderConstrained" in the Forum.

Thanks
