Question Fillet/blend edge

Rhino 7 has (finally) introduced “setback” fillets.
There are two different modes: fillet edge and blend edge.

The first should return less soft G1 fillets; The second should make softer, G2-type fittings.

In my opinion, as happens in many other cads, the Setback type fillet should be defined by the user, that is, it is he who must establish in which edges he should execute this type of condition, and not which command to use, in all selected edges, this type of condition.
So why can’t setback be defined inside the “fillet edge” command? it is an unjustified discrepancy.
In my opinion, the whole Fillet sector should be better reviewed.

(in Solidworks, for example, you choose the fillet command, and within it, you decide whether to fillet in G1 or G2, and establish the points where you want to create a setback fillet, if necessary, but not in all edges).

The Fillet edge command does not contemplate setback fillets, why? We would need a single “fillet” command, in which, through various command line options, set the various conditions (G1, G2, setback, etc.). It would all be more functional and logical.

The developer should better structure and organize these aspects, it is useless to create different modalities of connections making everything redundant and inconsistent.


It would be desirable that within the “blend edge” command the “setback” blending mode is considered as an option, a particular case, and not that it is ordinary.
It would be more logical to consider an option that allows you to activate or deactivate (as well as choose in which corners to apply the setback), as it happens correctly in almost all parametric cads.

A setback everywhere is not the best! there is also the possibility of creating a corner with 3 edges also in this way:
