New API Help Format

Posted: 31 Jul 2015 08:44 AM PDT

With the latest release of Fusion, a new format for the syntax in the help has been introduced.  Although this change has been made for the Fusion help, the same help system is also used for Inventor so these changes can also be fairly easily made for the Inventor API help too.  Because of that I would like to get feedback from both Inventor and Fusion users about this new format.

In the old help, the syntax was shown using a pseudo Python or Javascript syntax that represented that function as if you were writing the function.  In Inventor it uses a VBA style syntax.  It was pseudo code because it also included argument types which aren't actually needed in Python or JavaScript but were include because they help to provide the full description. 


Old Style
Below is an example showing the MirrorFeatures.createInput method in both Python and JavaScript.



And here's an example of how properties were represented using the isSuppressed property of the MirrorFeature.




New Style
With the new syntax style it attempts to show how you would actually use the method, property, or event in your code.  So instead of showing the format for the person developing the API, it's showing the format for the person using it. It's not really a runnable sample but in many cases is very close.  Below is  the new format for the same method and property illustrated above.





And here's the syntax for the isSuppressed property.





There is also event specific syntax.  A Python example is shown below.  This illustrates fully what's needed in order to implement that event.



You can see all of the new help at the Fusion Learning Site.  Click the "Programming Interface" link and then use the table of contents to access the "Fusion 360 API Reference Manual" section, as shown below.



I Need Your Help
I can use your help with honest opinions about whether this new format is better than the old and then, with whatever format we continue with, suggestions about how to improve it.  I know there is still a lot of room for improvement.  Every time I use and look at the help I see some things that could be improved and I work on some of them in each release, but I'm sure some of you have some other and better ideas.  Feel free to post comments here or you can also send them directly to me at

Virtual Singapore: A Platform to Solve Emerging and Complex Challenges

Posted: 30 Jul 2015 05:00 AM PDT

Virtual Singapore

The National Research Foundation (NRF), Prime Minister’s Office, Singapore, and Dassault Systèmes have announced a cooperation to develop Virtual Singapore, a realistic and integrated 3D model with semantics and attributes in the virtual space.

Advanced information and modeling technology will allow Virtual Singapore to be infused with static and dynamic city data and information.

Click to TweetClick to Tweet: “#VirtualSingapore will allow citizens, business, government, researchers to model city data”

Virtual Singapore is a collaborative platform with a rich data environment and visualization techniques that will be used by Singapore's citizens, businesses, government and research community to develop tools and services that address the emerging and complex challenges Singapore faces.

This project will build upon Dassault Systèmes’ 3DEXPERIENCity to create a dynamic, 3D digital model of Singapore and connect all stakeholders in a secured and controlled environment.

The model will employ data analytics and simulate modeling capabilities for testing concepts and services, planning, decision-making, researching technologies and generating community collaboration.

With images and data collected from various public agencies, including geometric, geospatial and topology, as well as legacy and real-time data such as demographics, movement or climate, Virtual Singapore users will be able to create rich visual models and realistic large-scale simulations of Singapore.

Users can digitally explore the impact of urbanization on the city-state and develop solutions that optimize logistics, governance and operations related to environmental and disaster management, infrastructure, homeland security or community services.

“Singapore is the most advanced city in the world in terms of leveraging technology to plan and manage its transformation over the next decades, and its government’s forward-thinking vision towards a Smart Nation parallels our own mission to harmonize product, nature and life through 3D universes,” said Bernard Charlès, President & CEO, Dassault Systèmes.

“Cities are some of the most complex ‘products’ created by humanity. Through more efficient and accurate predictions of future experiences within these cities using state-of-the-art tools and applications, we can better anticipate national resource planning or provision of services, and contribute towards a more sustainable quality of life. We hope to see other cities echo Singapore's exciting initiative.”

A Sprinkling of Smart Dust

Posted: 27 Jul 2015 03:15 PM PDT

Written by Catherine Bolgar

6-18-2015 12-53-22 PM

The "Internet of Things" allows industrial companies to tune or monitor equipment and processes with sensors. But how can these be best positioned and remain connected? One solution is to use smart dust, deployed in oil refineries, industrial process automation, breweries, waste-water treatment and elsewhere.

Smart dust was conceived in the mid 1990s by Kristofer S.J. Pister, now professor of electrical engineering and computer sciences at the University of California, Berkeley. He wanted to  create tiny, diffuse wireless sensors that could be used for product tracking, temperature monitors, defense surveillance and other such applications.

By 2001, Dr. Pister's team had developed an autonomous sensor the size of a grain of rice, containing five solar power supplies. "It was completely useless for anybody trying to do anything practical," he says.

But with growing industry interest in smart dust, he founded a company, Dust Networks (acquired later by Linear Technology), to work on possible industrial applications.

When we got out of the university setting, we learned that size wasn't particularly important, but power and reliability are," Dr. Pister says.

The sensors had to be so efficient that their batteries would be able to last a decade, and communications technology had to function in harsh industrial conditions.

"We found that as we made these things better, the package gets smaller," Dr. Pister says. The Dust sensors are now about the size of a sugar cube—too big to inhale, as some had feared—and are fixed in precise spots, so  "they aren't thrown willy-nilly in the breeze," he notes. "They aren't going to wander."

The sensing work itself—detection and measurement of temperature, flow rates, vibrations etc.—doesn't require much power, but communicating it does. As a result, Dr. Pister's team focuses on extremely low-power radios, turning them on only at the right time (down to the microsecond) either on a schedule or when the sensors have information to report.

To further save energy and improve reliability, the sensors are wirelessly connected in a mesh for efficient batch networking, communicating among one another to send data in short hops that don't require much energy.

"The n6-18-2015 12-59-54 PMetworking aspect is similar to what goes on in the Internet," Dr. Pister says. "It's [about] how to build a reliable network when individual paths may be unreliable. We had to come up with different optimum solutions than what people are used to in radio."

Typically, a sensor system has many low-power transmitters and one really good receiver, in what is called a "star-connected network." However, in an industrial setting, the physics of a star network doesn’t work well. “The nature of radio frequency propagation and thermal noise in receivers mean there is some tradeoff,” Dr. Pister says. “If anything changes in the environment, it interferes.”

Sound travels like ripples when a stone is dropped into a pond, he says. When a ripple hits a wall, it reflects back and makes patterns. "If you're a radio, you don't want those patterns. You get destructive interference," Dr. Pister explains. Industrial settings are full of such radio-reflecting walls.

That's where the mesh really shines," Dr. Pister says. You don't need any one particular length between devices. Everybody can talk to everybody as long as [a] path is available. Packets [of data] keep going through, no matter what happens in the environment."

The technology continues to improve and new applications continue to arise. "It's not out of the question that 10 years from now there's a whole new deployment," he says. "The interesting thing, especially in the industrial process space, is that standards tend to last a long time."

The first Dust sensors, deployed in 2007, are still working with their original batteries. While new generations may use less power, they operate with the same protocol, so companies don't have to replace older models when a new one comes out. Linear Technology continues to sell products launched 30 years ago.

The quest to reduce size and energy use continues. One research focus is "energy scavenging," whereby sensors can be powered by vibrations from the equipment they're monitoring, or by differences in ambient temperature. "It's not science fiction," Dr. Pister says. "We have customers who integrated our wireless sensors that are running off solar power or temperature differences in a refinery. It's part of the future of infinite-life products."

C++ is Here for Fusion

Posted: 27 Jul 2015 02:42 PM PDT

The latest update for Fusion went out this past weekend so if you've run Fusion since then you have it.  You'll now see a new "C++" option when you create a new script or add-in, as shown below.


That will create a new C++ project.  A C++ project consists of a .manifest file, (the same as Python and JavaScript), but also a .cpp file and two project files; a .vcxproj file for Windows and Visual Studio and a .xcodeproj file for Mac and XCode.

The API is the same as what's been exposed for Python and JavaScript.  In fact the Python and JavaScript interfaces are layers on top of the C++ interface.  Each language has it's own quirks so the API is used a bit differently for each one but it is the same API. You can read all about the C++ quirks in the C++ Specific Issues topic in the Fusion 360 API User's Manual.

Some highlights of the C++ API are:

  • You can now deliver your applications as a binary file instead of source code.
  • You now have a typed language which means you'll be able to user reliable Intellisense (code hints) when writing your program.  This is a huge benefit and means you'll spend a lot less time in the documentation looking to see what methods and properties a certain object supports and what the arguments are for a particular function.
  • Performance is much better than Python and JavaScript.
  • You get to use a development environment you're already familiar with.

Probably the biggest downside is that because you're delivering the runtime binary, you have to compile your code separately for Windows and Mac.  Except in cases where you're using Windows or Mac specific libraries you should be able to have a single set of source but you'll need to compile it on Windows to create the Windows compatible .dll file and then also compile it on a Mac to create a Mac compatible .dylib file.

You can post any comments (positive or negative) or problems you have to the Fusion 360 API forum, where I'll be watching.
