I just tried this with a 5 m cube, generated both tets and voronois and then cut them, and it does appear to produce slightly different behaviour.

**Tet blocks**

```auto
model new
block cut set minimum-id 5
geometry import 'test_geometry.stl'
block generate from-geometry

block cut joint-set dip 0 dip-direction 360 spacing 1 ...
                number 4 origin 0 0 2 jointset-id 10

```

**Voronoi blocks**

```auto
model new
block cut set minimum-id 5
geometry import 'test_geometry.stl'
block generate voronoi

block cut joint-set dip 0 dip-direction 360 spacing 1 ...
                number 4 origin 0 0 2 jointset-id 10

```

@jhazzard one for your wisdom, perhaps?
