Switch to/Activate Design environment? crash...

[Anonymous]

In the CAM samples it is shown how to switch to the CAM Environment. This works great.

I'm setting up an Add-In for production and trying to make it as easy as possible for the users.

The add-in makes some changes in DESIGN, then jumps over to CAM where it updates and posts the toolpaths.

This all works great, however when I try a similar approach to switch Back to the DESIGN environment after all that is done, Fusion crashes...

Mind you if I make a small add-in that only makes that switch Fusion doesn't crash... What could I be doing to cause this, or is it more likely a bug?

This is what I'm doing to try and go back to DESIGN:

activateDESIGNWorkspace = _ui.messageBox('Activate the DESIGN Workspace?','DESIGN Workspace Activate',
                                                 adsk.core.MessageBoxButtonTypes.YesNoButtonType,
                                                 adsk.core.MessageBoxIconTypes.QuestionIconType)

if activateDESIGNWorkspace == adsk.core.DialogResults.DialogYes:
    designWorkspace = _ui.workspaces.itemById("FusionSolidEnvironment")
    designWorkspace.activate()

In my experience, I have found that crashes occur when switching back to the design workspace if a fusion input dialog is created in the design workspace before switching to the CAM workspace. I have found that the tkinter library is useful for creating dialogs in these scenarios. A tkinter dialog will not cause crashes and all the necessary information can be extracted from it.

Indeed there is a fusion input dialog before the switch...

Thanks, I will try and look into tkinter!

@zachesenbock have you managed to figure out a way to make a tkinter dialog modal in the context of Fusion 360? I've found that if the user clicks anywhere other than the dialog, they lose the dialog behind Fusion 360. I haven't found a way to stop that, the documentation suggests the tkinter dialogs are modal by default, but also offer a way to pass in the parent window but I couldn't figure out what value represents the Fusion 360 main window.
