What do you like best?
Visually, Fusion 360 has a clean and easy to understand interface. It is generally intuitive and there are many tutorial videos that are available. The feature that sets Fusion apart from competitors like solidworks is its "Sculpt" modeling workbench. This freeform tool is great for roughing out what would normally be very complex surfaces and is handy for creating ergonomic models like handles. The ability to blend sculpted forms with a more parametric modeling system is similar to the capabilities one might have in Catia using Imagine and Shape. This is however a more simplified version.
The price is also a hard aspect not to like. Free for enthusiasts and $300/year for businesses is impossible to beat.
What do you dislike?
While Fusion has many positive features, It does have some quirks that make it feel like a work in progress relative to some of the more mature 3D modeling platforms. One area that could use improvement is the sketching function. There are a number of issues here. The most annoying is the inability to reference model geometry without projecting it into the sketch. In larger models, sketching also becomes tedious when sketching on a plane that is in the middle of other components in the model. It makes it nearly impossible to select and edit the sketch. A solution to this might be to be able to toggle the visible geometry in the model on and off while in the sketch so that it is unselectable when not needed.
A few other quirks:
There does not seem to be any function to make parts transparent (other than changing the material). This gets very irritating in more complex models.
Difficult to quickly change the color of parts (without changing the material)
True 3D sketching is lacking
In the Sculpt workbench, when creating bodies, if multiple are created in the same instance (sometimes I will create multiple iterations of a form and then only use one), if bodies are hidden, they dont always stay hidden which can often show way more surfaces than is necessary.
Recommendations to others considering the product
Great for independent designers, startups and designers interested in low cost complex modeling. Still leaves a bit to be desired for more complex surfacing but is an excellent tool which will hopefully improve even further.
What business problems are you solving with the product? What benefits have you realized?
Fusion has been an excellent tool for design concept models, specifically for ergonomically dependent products that have handles and more sculpted forms. In our business, SolidWorks is the dominant standard with clients but as a designer, this offers much of the capability that SolidWorks offers, plus some added benefits. That being said, solidworks in a few areas has the feel of a more mature program. I hope that given some more development and time to set in to the marketplace, Fusion will become a more standard software.
