Hey All,
I am getting a pop-up error when trying to create a new Add-In using Fusion 360:
"Unable to find default manifest!+Script with same name already exists!
Does anyone know how to resolve this issue? I broke my Fusion! 😞
Error when Trying to Create New Add-In
I've never run into that before but am able to reproduce the problem. The reason I've never seen it before is that I always change the default name "NewAddInX" to some other name that's more identifiable for what my add-in will be doing. Try that and see if you can now create a new script or add-in. It should be working with the default name though and I'll log a defect.
You're right. Thanks for letting me know. This must be a recent regression because I create new add-ins all the time. I'll update the defect with this additional information and raise the priority. A workaround for now would be to go to the folder where add-ins are created and copy an existing one where you'll need to rename the folder, the .py file and the .manifest file to the new name of your add-ins. You'll then be able to open it and edit the code.
Accepted solution
The problem is that with the latest Fusion update some files are missing that are needed to create a new Python add-in. We've fixed it and the fix will be available in the update in April but until then you can use the files I've attached. To create a new add-in, unpack the files either in the default location for add-ins or any location. You'll need to rename the folder and the .py and .manifest file to have the same name and be the name of the add-in. You should also edit the id in the .manifest file to be a unique GUID. Here's an online tool you can use for that. https://www.guidgen.com/ If you put the files in the default location, Fusion should now see the add-in and it will be the list of add-ins. If you put it somewhere else you'll need to use the green "+" in the Scripts and Add-Ins dialog to add it to the add-in list. Now you should be able to edit and run it as usual.
