I believe there is still much to improve in the way computers are used in the design of structures. The default modeling experience in Autocad has not really changed ...since when? Yet, it's one of the largest softwares out there. I think the modeling paradigm is flawed because it originates from a need to fit lots of data into a tiny ram, and the whole workflow is built around this. Yes, there is the APi - but the differnce between a good UI and an API is the difference between Photoshop and ImageMagick.

Project pipelines: Design information is passed between specialists and project offices. Here DWG - being as popular as it is - is used like a checkin of a git branch - it is as well suited for this as a docx document. People manage, though, with a bit of manual project specific work thrown in. No amount of fancy viewers is going to fix this.

People have started to notice that good graphics are available from 'off the shelf' and that handling the basic geometric primitives is not really rocket science. I'm confident OnShape will be followed by a sleuth of new modeling tools soon - and probabably not from Autodesk. They are too busy protecting their entrenched dominion. I might be wrong though.

Fusion 360 is becoming a small revolution among my makerspace.

Which features of Fusion would you consider the most important for your usage? Why is it gaining traction?

It allows people who are familiar with 3D printing to learn how to use the CNC machines without a big investment in single-purpose machining software.
