Hello Hans, thank you so much for the reply. Your original post also cleared up the most straight path to go from MOI to Fusion and back (exporting as IGS out of MOI and exporting as STEP out of Fusion for MOI reimport), which is something I was meaning to look into for a while. This worked perfectly.

Edge features are indeed straightforward to remove in Fusion, but a lot more can actually be done with Push/Pull. Now of course the Fusion360 UX is as awful as it has always been and I don't want to spend more than a few seconds in this software, but this will be without a doubt a handy companion to MOI in some cases. Here is some very quick testing on a simple part :

I know that many users have been asking for a full featured History feature in MOI, but imho this is a bit of a misguided request. I feel like what most people actually need is *some* way to edit features after the fact, but not necessarily on a timeline (even though linear timeline editing is obviously the first idea that comes to mind). This non-linear Push/Pull editing paradigm (which I believe is at the core of DesigSpark) would really work fantastically well in MOI.
