Autodesk App Store - Information for Fusion 360 Developers

This guide is for developers and content providers new to publishing add-ins and other content on Autodesk® App Store – either free, trial or for fee versions. It outlines best practice guidelines and a few requirements for publishers to follow when creating products for the Autodesk App Store. These guidelines are designed to ensure that users on Autodesk App Store have a consistent experience when downloading multiple products from the store.


You will be presented with a detailed list of requirements for publishing on App Store when you first register to be a publisher. The information that follows is a summary. If there are any differences, then the online Publisher Agreement takes precedence.

All content types 
Most of the information we need from you is collected via the web form you complete when submitting your content. This includes gathering information to create a HTML ‘quick start’ page that is included with the download of your product and viewable online. Other requirements are:

  • Your product must be relevant to (and usable with) the latest version of Fusion 360.   
  • The ‘documentation’ information you provide when submitting your app will be used to create a standard format HTML page, and must allow the user to quickly understand how to use your product. You can reference additional information (for example, additional help files posted on your website) from the standard HTML documentation.
  • We strongly recommend you make use of the standard Autodesk App store app installer we create for you.  Installers can be created for Windows and Mac depending on which platform(s) you submit your app for. Fusion 360 apps are installed per user in a user specific directory and do not require any additional privileges.
  • If you use a licensing system then it must allow your product to run as soon as it is installed by the user. This means either instant activation (e.g. online activation), or your product must run fully functional for a time-boound'grace period' that is long enough for you to send activation information to the customer.

Standalone applications and other content 
There are no additional requirements for products that are not integrated with Fusion 360. Such products might include eBooks, video tutorials, industry specific calculators, and the like.


Command Access 
Access to your apps commands should be in a logical location. You are strongly discouraged from creating a new panel in the toolbar but should instead use existing panels or in the case where your functionality doesn’t fit within an existing panel, your command(s) should be added to the “ADD-INS” panel, as shown below. Users can choose to promote your command(s) to the top level of the toolbar if they use it frequently.

Add-In Loading Efficiency
Minimize add-in start-up time. Fusion add-ins are loaded when Fusion is started so every add-in affects the time it takes for Fusion to become available for the user to begin working. Fusion supports getting some add-in performance information so you can measure the load time of your add-in.

  1. To get add-in performance information you need to create the environment variable “APPLOG_FOR_PERFORMANCE=yes” before starting Fusion. When running Fusion it will now log performance information to a log file in your user specific local appdata folder. For example:

    %localappdata%/Autodesk/Autodesk Fusion 360/5RL5Q5DP5XU5/logs/AppLogFile20150819T145311.log

    If you search for “ran script”, you’ll see a line for each add-in in the log file where it will have the load time and run time listed. The load time is the time it takes for Fusion to load the add-in from disc and the run time is the time it takes to run the run() function. You’ll see that most add-ins load and run in around 0.005 seconds. If your add-in is significantly slower than that you should investigate why. You should just be adding your command and connecting to the command events in the run method. Additional loading of libraries should only happen once an add-in command has been executed.
