OpenNURBS.OnBox vs Grasshopper Box type

Hi all,

I'm fiddling with this brick wall of mine and when it comes to actually generating the geometry I used to feed a bunch of planes and dimensions into the CenterBox component - the 3d box generated is so nice and easy on my computer. Unfortunately I can't seem to be able to reproduce the effect in VB.

I can create an OnBox object, but it just does not compute when I feed it back to Grasshopper (data conversion fail from Goo... ), I figure it is not a native data type and only meant to be shared between scripts.

 While producing RhUtil.OnBRep_Box is easy enough the BRep is a lot more heavy to draw for grasshopper (I can see a significant differance). Is there a way to create a grasshopper Box type object (a GH_Box) from within VB?
