Not infrequently I find myself drawing a line to a projected line and then wanting to fillet the intersection.
Currently this is not possible.
Understand it makes no sense to fillet a projected line, but F360 could fillet the drawn line in such a way that it then intersects the filleted line a bit further from the original point of intersection. The projected line would just be a tangent to the fillet at that point.
That's the suggestion!
