Is this too far away in the distant future Michael, or maybe something that you're thinking about in v4.
It seems that most modern cad systems have that sort of functionality, (spaceclaim, fusion360, onshape, etc) but lack the superior surface building power of MOI. It'd be nice to have that feature so we could stay inside the wonderful world of MOI without exporting.

Hi niko - I would like to overhaul the interface to fillet at some point in the future but I would place a higher priority in filleting on just trying to have a more robust filleting mechanism that works for more cases. A more interactive "direct dragging" interface is something I view as a lower priority than that and so it's probably further off in the future and not too likely to show up in v4, sorry.

I would also really like that feature.

Handle on blends would be nice also.
Being able to move the blend start/end on curves would be magically delicious.

I agree Michael, a more robust fillet should take priority. I am always getting into situations where it just wont calculate.
