Pllleeease, anyone, how do I get this done in Bryce??

Tnx

i will look into it,
BUT, you do realize Bryce is NOT a modeling program ?

Bryce is specialized in Landscape scenery and form importing modeled figures from other programs. There is even a direct link possible with the free program DAZ|Studio, which has limited modeling capability, but usually is used for POSING content that was modeled in yet another (real) 3d modeler.

SO,
most of the time you dont try to model things in Bryce, but off course, sometimes you have to break the rules...

EDIT:
if no primitive exist i think i would do this (but not at home ftm, so not really sure) as follows:
3 cubes intersecting, middle one straight up, other 2 slanted; make middle positive, other 2 negative and then group them: the slanted cubes will cut off the sides of the mifddle cube (socalled boolean)

I must tell u that I've used Bryce for modeling for qutie a while. Proof is the image u see.
The solusion I found is same as text (Lattice). BTW, the wood texture is my own doing.
Tnx for comment
