Creating massing model - Sweep problems

Hello

I wanted to ask you guys why my definition is not working properly.

Back story:
I modeled a massing option for a building (see pic)

.

It is a series of extrusions with sweeps around them. Then I needed to do a number of such massing options so I thought I might use Grasshopper to make things faster. Here where the grasshopper definition comes in.

The problems are:
a) The tween between curves doesn’t quite work with 2-degree curves (this is minor problem i’d say)
b) Array profiles along the curves of the slabs is not accurate

Pls help!

The tween between curves doesn’t quite work with 2-degree curves

Check out Tweens with Pufferfish, Degree 2 curves won’t be an issue if you set the R(Refit) input to 3.
