How to write code for this upper blue floor ?

[ShubhamBhatia]

For my work, I need to create similar upper floor  (Blue) over extruded footprints. It will be very helpful if you could share the code to achieve this. 

Thanks in advance.

Your solution is the same one I just posted on another thread....

Footprint--> extrude(120) comp(f) {top: Roof1 Roof2 | side: Wall}

Roof1--> something ...

Roof2--> something else....like making it smaller, extruding for a parapet, texturing...

Hi Shubham,

You can use the following sample CGA Rule

/**
 * File:    split.cga
 * Created: 8 Mar 2019 05:09:16 GMT
 * Author:  Imran Khan
 */

version "2018.0"

attr height = 1200
attr floor_ht = height/3

Footprint -->
	extrude(height)
    split(y){floor_ht:groundFloor|floor_ht:middleFloor|floor_ht:topFloor}
    
groundFloor -->
color (0.3,0.3,0.2,0.5)
x.

middleFloor -->
color (0.3,0.5,0.8,0.5)
s(400,400,800)
center(xz)
x.

topFloor -->
color (0.3,0.5,0,0.5)
s(200,200,400)
center(xz)
x.‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The Output will be
