Fusion 360 has been recently adopted by some members with little or no previous experience on 3D CAD Modeling.
Before we get all too excited with the possibilities of Fusion 360, we must be aware that this is not a software package designed for big assemblies. Ok, it's modern, it has an intuitive user interface, easy to use, and it allows you to do CAM and CNC with it.
BUT. It is possibly not right to model an entire locomotive, specially if you want to model everything up to the most tiny detail.
And this other video that the same author made some time after:
The first video was posted just three weeks ago.
This is a REAL problem that appears to be acknowledged by virtually everybody that tried to do serious stuff (read: big projects) with Fusion 360.
I mean, my locomotive lacks a huge deal of detail because you all know which is my approach and what I favour most, but it still has 2155 total parts with more than 600 individual parts as reported by the software. I mean my loco doesn't have a single part with complex geometry in it. Everything is flat or geometrically straightforward. I can't imagine the number of parts and complexity of same that a true model scale locomotive may have.
The workaround to big assembly sluggishness reported on Fusion 360, is just that, a workaround. In my book it's totally wrong. What he proposes is to ground all the subassemblies to their absolute positions in the main assembly to prevent you having to move them. Well, that defeats all the purpose of parametric CAD, and you end working on something static that is not reacting to isolated changes on parts or subassemblies (!?)
I do not want to be negative about this software because it obviously has a lot of strengths. In fact, I did consider to migrate to Fusion for any new projects because it also supports the Apple platform and I may get trapped with having to pay huge licence fees on what I currently use (Solid Edge) because the spare license I'm using for free be reclaimed by my friend. Another reason is that I do not have the CAM module because my friend doesn't use it. However, after investigating it a bit I'm really concerned that Fusion 360 would work at all for the kind of performance I'm currently used to.
So, I'm posting this just to give some awareness of what could happen if somebody engages themselves to use Fusion 360 for too serious stuff or as a replacement of one of the more mature 3D CADs around. Please do not take this as a negative comment, but just as a matter of information in case this possible issue was not known.
