Using Fusion 360

I am learning to use Fusion 360, and I cant figure out how to cut down a part to the size I need. Any help appreciated.

Not sure if this is the best way, but I usually construct a plane which I use with the split body function and then delete the other piece which I don’t need. Make sure the part is delinked so that you can edit the bodies.

Imo, switch to solidworks. Works better in the long run.


Even if you don’t do solidworks as it takes a while to get the free key sponsorship, autodesk inventor 2019 works much better than fusion

I’m following this thread because I’m about to learn Fusion 360, too. Both of these statements are not helpful and in my case are actually false. I can’t run either of these on school computers, so neither works better for me than Fusion 360.

@kailasbk , thanks. Can you do something like create a solid and subtract instead? On 123D Design that’s something I prefer over splitting because I can also make cut-outs the same way.

@callen yes, you can create a sketch and when you extrude it select the subtract option which will subtract it from the body it would overlap with.

I actually use fusion 360 to cad robots and have experienced your problem what you have to do is open up the file such as a 2 by 35 long c-channel. Create sketch and sketch out what need to be cut then use the command split bodies and delete what you dont want and save as a different file.@61004JAR

This perspective that Solidworks (or Inventor, Siemens NX, OpenSCAD, FreeCAD or what have you) solid modeling software is better than Y frustrates me. The best problem solvers will choose the most appropriate tool for the job. This means being able to adapt to using whatever tools you have the capability to use sometimes. SW and company have their place, and for those who end up in big companies who have the infrastructure/budget for one of the big name tools, you’ll have no choice.

Use Fusion360 when you need:

  • Support for weaker hardware or infrastructure, which is typical in education environments and makes this software the go to almost every time
  • Collaboration tools. Shared workspaces and assemblies, as well as their implementation of a sort of version control makes working on models in a team significantly easier
  • A good piece of modeling software to use if you don’t have a budget: you can use Fusion360 commercially as a startup or small company that has a net profit of less than 100k USD per year. This is huge for people like me who want to get into doing commissioned work or start a small company and not break the law or the bank. A lot of us don’t have the option to use SW or Inventor under an education license due to the desire to commercialize some of our work.
  • A CAD/CAM workflow: Fusion360 can generate gcode for CNC toolpaths and the like from the your models that you make in it. It’s really useful and convenient, seeing as tools like MasterCAM (or whatever people use today) require more overhead and introduce an added workflow into your manufacturing process.

There’s some more features that you add and lose vs other solid modelers, but these are the big ones I can recognize off the top of my head.

Having just been learning Fusion 360 myself, I’ve found this plane method to be really nice. The planes can be constructed so quickly by using “mid plane” or “plane through two edges” for the majority of cuts to be made. Other planes can be made pretty quickly, too. It’s so nice that I think a cut-out would be easier by doing a few plane cuts, deleting the removed piece, and reassembling the remaining pieces into a new whole.
