Help with drawing steel rebar in 3d?

[TarikHKJ]

Hi,

I have these two sections of a reinforced concrete column, Section A: is located at elevation Z=0
and Section B: , which is 3.38 meters above Section A Z=3.38 , the two shapes are concentric.
ٍSection A is 100x50 cm, and Section B is 80x40 cm, Rebars are closer together in section B than they are in section A


I want to extrude the red circles in the section A and make them extrude inclined to connect with Section B red circles,

In other words, the steel rebars in the column are inclined to make the column section smaller,


Thanks and sorry for my horrid English, not a native speaker
