Autodesk Inventor Fusion, Ready for Inspection
Autodesk Inventor Fusion now available for download as a technology preview.
A little more than two weeks after Siemens PLM Software unleashed Solid Edge with Synchronous Technology 2, the second incarnation of its mid-range direct modeler, Autodesk delivered its own version as a technology preview. This week marks the premiere of Autodesk Inventor Fusion — not as a series of video clips or screenshots but an executable code, ready for test drive. (The code is available from Autodesk Labs.)
In February, when Autodesk gave us a peek of Inventor Fusion, it was presented to us as a technology that would bridge parametric and direct modelings. At the moment, the bridge is still under construction.
Kevin Schneider, Autodesk’s technology evangelist for manufacturing solutions, said, “Later this year, we’ll be previewing an Inventor Fusion feature where a user will be able to make an explicit edit [direct edit], but when that’s completed, they can choose to continue to design in explicit [mode] or return to the parametric or history-based environment. When they do [the latter], they’ll be allowed to convert their explicit feature into a parametric feature.”
In the announcement, Autodesk reveals, “The June 2009 preview is the first step toward Autodesk’s goal of providing seamless bidirectional parametric and direct workflows to users by allowing them to adopt the modeling approach that best fits their needs in a single application. The company is planning a second technology preview this fall that will enable users to perform direct modeling for fast changes and then see their changes updated in the model’s parametric feature history, maintaining crucial design intent.”
The First Incarnation
The first release of Inventor Fusion exhibits a direct modeler’s characteristics, with the ease of use and push-pull modeling we’ve come to expect from such programs. Autodesk gave me access to the software with limited documentation. That was intentional, Schneider later revealed. The way an unassisted user explores the software can give him and his development team clues about how intuitive the interface is.
My editorial career has exposed me to various 3D software products and how they work, but I am by no means a CAD expert. (In fact, I don’t mind admitting that I feel more comfortable in SketchUp than in a CAD program.) My limited CAD experience notwithstanding, I found Inventor Fusion’s commands quite easy to figure out: I pull on a face to add height to a profile; I select a feature and push it along an axis to move it; I move faces to adjust the volume of my 3D model; and so on.
I normally think of 2D sketching as precision drawing, but the flexibility of Inventor Fusion’s sketch mode makes me rethink. Because I can push and pull on lines, arcs, and intersections to adjust their length, height, and angle, I felt I was in an exploratory environment.
I also imported a STEP file, a Jergens bracket found on 3D Content Central, to see how Inventor Fusion handles imported data. I was able to use the Find Features command to let the software automatically scan the imported part and build a bill of features (extrusions, faces, holes, bodies, and so on), cataloged under the Browser. Since the Browser is located roughly where you’re accustomed to seeing a feature tree, you might be tempted (like I was) to select a face or a boss from it when you want to modify it. The recommended approach, Schneider told me, is to use the Move Face command or to select the boss in question right in the model and drag it to a new location.
In modifying imported geometry, Inventor Fusion sometimes produced odd results (watch the video below). Schneider is confident that, as the code matures, Inventor Fusion will get better at resolving geometric conflicts that arise from such edits; consequently, the oddities I encountered with the present code will disappear.
Despite some awkward behaviors, Inventor Fusion struck me as a promising start, a harbinger of the direct-editing capabilities that will eventually find their way into commercial versions of Autodesk Inventor.

great coverage. great video. I linked it up on the solidsmack post.
Josh: Thanks for the link!
Thanks for helping spread the word.

Hi Kenneth
Just to let you know that i made a quick post base on my first impression.

Solid DNA: Thanks for writing. I read your blog post. In it, you wrote, “When you open the program, their is no mention of part or sheet metal or assembly, just an empty space.”
Perhaps one point of clarification might be in order. According to Autodesk, Inventor Fusion is not meant to become a product of its own. It’s meant as a preview of the technology that will eventually become part of Autodesk Inventor. For this reason, I didn’t consider the absence of sheet metal, assembly, and other features in the first incarnation of Inventor Fusion as a disadvantage.

Thank you for clarify this. And i understand this is worth to make the note.
My review was more a walk thru to have an overall picture. Has mention other autodesk bloggers will do more extensive review.
On the other hand, i believe, even if this a Technology Preview, most of those who will download or looking for some informations might expect to found working environment. Further down in my article I mention how “assembly Structure” is handle.
Plastic and machine parts are process with some similiraties so they can be inside the same environement. Sheet metal is a whole different process. Same for assemblies and all it’s derivate,
Also base on other technology similar to fusion, each environement have it’s own set of rules. So Inventor fusion will have to come up with a way to make distinction even if it’s not intend to be a stand alone product.
If it is the case, not being a stand alone programe, one way i see, is to have a bolt on feature inside each environment. This way fusion technology will know how to behave inside each environment. If that is the case, i wonder why they have give assembly structure possibilities along with part feature?
But the most important point is Autodesk seem to go in a direction where all their softwares and technologies will have a common core and this is what really caught my attention in this TP1. Fusion is more for me the fusion of product and not the fusion of ( what i call) linear and non linear modeling.
We will have to wait for TP2 and later to have a better picture how this technology will spread among Inventor product line.
Sorry for the long reply
hope you don’t mind.

Solid DNA: Good point! Hope you don’t mind me using an excerpt from your response as Reader Comment of the Month in my upcoming Virtual Desktop MCAD News (email newsletter) for July 11.
AutoDesk wasting their money on Algor and then imposing on a name that is already used to signify CAD integrated CAE is weak.
