I've now surveyed throught the Sculpt workspace's toolbar items, and was surprised in many cases by their current positioning.
It's not ideal, or logical. Which is just fine at this stage to get features created and stability proven. However, at some point the Fusion 360 team should (imho) book some time for rethinking the tool ordering, and making a true cleanup in that regard. This should be before people start making elaborate investments into i.e. writing books on the system.
I don't want to give a full analysis, yet (will do so if requested). Some of the issues I faced were Sculpt > Modify having loads of tools that have nothing to do with modifying T-Splines. Just an example (let's not get tied with that).
This goes hand-in-hand with the workflow discussions that have been done elsewhere in the forum (i.e. order of selection of elements vs. tool selection).
Are there no company-wide recommendations at Autodesk as to how a new tool should deal with its UI? Innovation is good, but so is consistency. Many people have referred to Inventor as a product that does these things pretty nice. Why be inconsistent with it?
My main point: don't think the UI is currently ideal. It's not. Book time for making it perfect (once the features themselves are all in and tested).
