This software has been so easy to use from day one! I couldn't be more thrilled with it. Being an SME, it is offered on an annual basis free of charge. My network of engineers are amazed I am able to accomplish what I have using this software when the companies they come from are paying thousands for licensing. I also would like to note that Autodesk offer an incredible specialization to really round out your skills via Coursera.
It appears to be evolving more towards large users with the 3D EXPERIENCE, while becoming less focused on small users like me, becoming more expensive and limiting the number of cores while most PC's now can easily run 8 cores. Of course it is great for non-linear and highly non-linear scenarios, and especially good at combing a huge variety of element types. I guess it is not best suited for linear analysis due to its high price, but even in this case you have to put in the balance the ability to make the best choice of finite elements and being so straightforward about actually using them.
The first PRO of Fusion 360 that always comes to mind is how versatile it is. Fusion 360 is the first CAD/CAM software that also includes other key features that CAD programs of this size don't have.
Fusion 360 has a generous licensing structure that gives those just starting out a place to start with a professional level CAD program. As a result, this has helped build up a huge community and user base around Fusion 360.
Fusion 360 is updated on a monthly basis. This has proven to be a huge advantage over Solidworks (something else I use) which is only updated once a year. The nice thing about monthly updates, other than regular bug fixes, is that the team can adapt quickly and no one is taken by storm with a big overhaul of the UI or features at the beginning of the year.
Create and modify designs from within the CAE environment. Although it has very basic capabilities, it is quite capable of generating 2D and 3D parametric designs. I have even generated some "fancy" designs which ended up being a challenge for draftsmen in specialized solid modeling CAD. I also like the fact that being somewhat limited, it forces you to stick to simple and effective design.
Addressing structural instabilities such as snap-through or buckling. This was such a challenge when I started using Abaqus, I had to take a course on "achieving convergence". Coming from there, I can see how SIMULIA has become increasingly able to give you the numerical tools or tricks you need to achieve convergence consistently. In the past I often feared running into different convergence issues as I moved across different produce sizes, leading to changes in the analysis approach, which would make it more difficult to compare them. I just went through a 12-size family in 5 dimensional scenarios each, without a single issue after ensuring convergence with the first couple of sizes.
Beautiful pictures. The post-processing of results enables me to generate highly illustrative, fairly easy to understand and elegant presentations, by controlling transparency and results shown independently on different groups, which I can select by material, location, etc.
Fusion 360 is a very simple program, so once you begin to draw more complex 3D models, the software gets sluggish and loses its fluidity.
It would be really nice if Fusion 360 could output a model as a SolidWorks file so I can begin to draw something out in Fusion 360 and then pick it up in SolidWorks when I need to do some more advanced functions.
Because Fusion 360 is a simpler program, there are a few functions such as 3D sketches that are not intuitive like all the rest of the functions are.
Exporting sketches. For example, you can import dxf for sketches, but you can't export dxf. This is a major drawback for me, because I often communicate with customers through dwg or dxf sketches. If I can't export dxf, my sketches in CAE are "dead". I have to redo them in the dwg sketch. It is so inconvenient, I often end up making the sketches in DraftSight, so I can export them to CAE but I still have the originals in dwg format.
CAE doesn't remember element type assignment by sets. Sometimes when I reconfigure or modify a design, I regenerate sets and surfaces, and this in turn updates material assignments, interactions and loads almost automatically. This doesn't happen with element types, so I often end up submitting a job with the wrong element types.
Mesh regeneration and re-mapping in 2D within the job. I need this a lot to model axisymmetric assemblies with sharp indentation the destroys the original mesh. I had it in MSC/MARC and it worked great. Abaqus has it only for 3D. I have tried alternatives like lagrangian/eulerian and eulerian domains but it's still more complicated.
Extremely well organized and friendly, reflecting the latest approaches in solid modeling and adding the FEA part so seamlessly for the user. It's a joy to use. I'm aware some people would complain about the meshing capabilities and thus prefer using HYPERMESH. Fortunately not my case. I did wish I had HYPERMESH a couple of times, but for most of my projects CAE meshing is fine.
Support is conducted via internet Q&A boards; newcomers to 3D modeling may find that articulating their questions in the language of CAD software is the tricky part — once they find the right technical term for what they're trying to accomplish, answers come quickly. Autodesk also provides a large library of educational tutorial videos that make the initial process of learning Fusion 360's interface much easier.
I keep getting the feeling that it is drifting away from small users. I don't feel so comfortable with the SWYM community approach. I felt much better when you could just email or call HKS and you would feel like you were talking to a real expert who understood your situation. When I was reassigned to reseller in Argentina, which is like the other side of the world for me, I appreciated the cultural closeness, but I had to say goodbye to the level of support I had from HKS and learned to "support myself."
Autodesk Inventor excels at daily core engineering tasks. When integrated with Vault management systems and part libraries, Autodesk Inventor is tough to beat when you need a mechanical design solution. When Inventor and Vault are setup properly it allows for a very efficient design workflow. I think it would be difficult to achieve the same amount of workflow efficiency with Autodesk Fusion 360, that said, Autodesk Fusion 360 offers a very good toolset at a much lower cost. I can maintain a yearly subscription of Autodesk Fusion 360 and get about 85% of the functionality that is available via the Inventor design suite for the cost of about 2 months of an Inventor subscription. I then also get access to manufacturing plugins with Autodesk Fusion 360 but lose a lot in the drawing environment. Inventor beats Autodesk Fusion 360 hands down when it comes to documentation.
MARC can do the job from an FEA point of view. It even appears better at a couple of things such as 2D remeshing and surviving with highly distorted meshes. So I regard it as a very competitive alternative. I prefer SIMULIA because the GUI is so much better, especially the ability to create actual parametric designs in CAE. ANSYS doesn't cut it for me. I tried it for 1 month and I would see how much I would struggle with convergence in large deformation and large displacement situations with hyperelastic materials with which I have to deal all the time. Also the GUI is not as well built an integrated as in SIMULIA.
I don't even bother doing an ROI. Without SIMULIA I would be pretty much out of business. Except for the fact that I could still have an alternative with MSC/MARC.
Price is becoming a more difficult hurdle for small users. It appears I have survived because there was a 50% discount on my small 6-token package. Without this special price I would have to close my business. I'm currently exploring alternatives.
A more flexible scheme enabling to add tokens over short periods of time or paying per use could be an interesting possibility.
