Insert external component

The Fusion API provides access to your A360 projects and the files as well. Through that you can insert an external component if you want.

The following sample lists your projects and the files in their root folder, and then lets you insert the selected one in the root component of your current model.

When testing the script you need to give a bit of time for the command window to pop up and the file drop down to update when you are changing the project.

Run Fusion commands

The online help already has a sample on listing all the controls in the user interface which also provides the id of  the CommandDefinition that the various controls reference.  You can also get to the sample from many help topics, including "UserInterface.toolbars"

This sample is very useful when positioning your controls within existing Fusion toolbars and panels and positioning your command adjacent to an existing command

However, if you are only interested in the command names and their id's then you can get them much simpler.

When you create your command then you create a CommandDefinition object and add it to the UserInterface.commandDefinitions collection.
This collection contains the internal command definitions as well. So you can just iterate through it to get the info you want. In Python it could be:

app = adsk.core.Application.get()
ui = app.userInterface

fileDialog = ui.createFileDialog()
fileDialog.isMultiSelectEnabled = False
fileDialog.title = "Specify result filename"
fileDialog.filter = 'Text files (*.txt)'
fileDialog.filterIndex = 0
dialogResult = fileDialog.showSave()
if dialogResult == adsk.core.DialogResults.DialogOK:
    filename = fileDialog.filename
else:
    return
    
commandDefinitions = ui.commandDefinitions
result = ""

for commandDefinition in commandDefinitions:
    result += "id = " + commandDefinition.id + "; name = " + commandDefinition.name + "\n"
    
output = open(filename, 'w')
output.writelines(result)
output.close()

You can search the content of the created file to find the id of the CommandDefinition you need. Once you have it you can Execute it - e.g. in Python running the Export command:

cmdDef = ui.commandDefinitions.itemById("ExportCommand")
cmdDef.execute()

Fusion add-in path

Some functions might require the full path to a given file. If you know it's relative path to the add-in then the following could help. The below samples show how to get the add-in folder in different programming languages - these samples are based on the API online help sample: http://fusion360.autodesk.com/learning/learning.html?caaskey=caas/CloudHelp/cloudhelp/ENU/Fusion-360-API/files/ExportManager-Sample-htm.html

Python

def getAddInFolder():
    import os
    folderPath = os.path.dirname(os.path.realpath(__file__))
    
    return folderPath

JavaScript

function getAddInFolder() {

    var url = window.location.pathname;
    var des = decodeURI(url);

    // remove the / at beginning
    if (navigator.platform.match('Win')) {
        des = des.substr(1);
    }

    var index = des.lastIndexOf('/');
    var dir = des.substring(0, index);

    return dir;
}

C++

std::string getAddInFolder()
{
#if defined(_WINDOWS) || defined(_WIN32) || defined(_WIN64)
    HMODULE hModule = NULL;
    if (!GetModuleHandleExA(
        GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS | 
        GET_MODULE_HANDLE_EX_FLAG_UNCHANGED_REFCOUNT,
        (LPCSTR) ≥tDllPath, 
        &hModule))
        return "";

    char winTempPath[2048];
    ::GetModuleFileNameA (hModule, winTempPath, 2048);

    std::string strPath = winTempPath;
    size_t stPos = strPath.rfind('\\');
    return strPath.substr(0, stPos);
#else
    Dl_info info;
    dladdr((void*) getDllPath, ∈fo);

    std::string strPath = info.dli_fname;
    int stPos = (int)strPath.rfind('/');
    if(stPos != -1)
        return strPath.substr(0, stPos);
    else
        return "";
#endif
}

Call web services from a Fusion add-in

There are more and more web services available out there on the net and integration with those can bring real value to your product. Sometimes the web service in itself is the real value provided by the add-in in which case you do not really need to protect the IP of your add-in and might as well use open JavaScript or Python instead of a compiled C++ project.

The following sample script is written in Python and it simply lists all the repositories inside our Fusion 360 GitHub account: https://github.com/AutodeskFusion360

When the user selects a repository from the drop-down combo box then the description field will get updated inside the command dialog. If the user clicks OK then the browser will jump to the URL of the selected repository.

 

It's fairly easy to implement such a thing in Python. I could use the http.client library for the HTTP communication, json library to turn the JSON response strings into arrays and dictionaries which make it much easier to get the data out of them, and the webbrowser library to start the default web browser on the system and show a given URL.
