# Combine lots after splits?

Hi.

I'm trying to generate basic building blocks from complex footprints. This works in general (BasicShape_1), but I'd like to refine it a bit. I used convexify to remove smaller extrusions and now I'd like to use the leftover bulk with the cube function.. however, sometimes I end up with multiple parts (see image below, green blocks), meaning I can't use that method. Is there a way to combine them?

Also is there a way to force "normal" behavior after splitting? When I scale the cube on the splits, the x-axis points up. Rotating fixes that, but I expect this won't work the same everywhere.

script:

```version "2014.0"

attr Roof_Angle = 33
attr Ground_Height = 1.0
attr Floor_Height = 2.8
attr Building_Height = Ground_Height + (aog*Floor_Height)

// ATTRIBUTES
attr daf = 0
attr aog = 0
attr Building_Width = 0
attr Building_Depth = 0

Lot-->
set(Building_Width, scope.sx)
set(Building_Depth, scope.sz)
BasicShape_2

BasicShape_1 -->
i("builtin:cube")
s(Building_Width,Building_Height,Building_Depth)
color(0,0,1)
set(material.opacity,0.15)

BasicShape_2 -->
color(0,1,0)
convexify(scope.sx)
comp(f){all: SubShapes}

SubShapes -->
case scope.sx <= 3:
color(1,0,0)

else:
color(0,1,0)
cleanupGeometry(all,1)
BuildCube_

BuildCube -->
i("builtin:cube")
s(Building_Width,Building_Height,Building_Depth)
set(material.opacity,0.18)
print(Building_Width)
```
