I designed several polylines in AutoCAD that does calculate perimeter for each, adjusted the polylines to find the optimal shape to make the building to appear as large and tall is possible while keeping it under the limit of 2100 wall segments and basement + 14 floors (adding 1 more floor would cause game to crash).
I planned this condominium using AutoCAD to make it as big as possible while keeping under limit of 2100 wall segments. I made 4 identical blocks with 9 floors, floors 1-7 having 136 squares and 60 wall segments, floor 8 having 88 squares and 44 wall segments, floor 9 having 24 squares and 20 wall segments. total 1936 wall segments. Then I built half-height walls that do not count towards wall limit. Then I build foundation and pool that does count towards wall limit but can be built even after 2100 limit was reached. It took about 5 hours to build in October 2018.
I planned this condominium using AutoCAD to make it as big as possible while keeping under limit of 2100 wall segments. I made 5 blocks with 8 floors, each floor having 116 squares and 52 wall segments. 52 x 8 x 5 = 2080 wall segments. Gate uses remained 20 wall segments. Then I built half-height walls, 24 segments per floor x 8 x that do not count towards wall limit, roof terrace with 66 x 5 half-height walls. Then I build foundation tall like one floor and pool that does count towards wall limit but can be built even after 2100 limit was reached. It took about 5 hours to build in September 2018.
Four identical tower blocks built around a little pool. Designed for aesthetic purpose only, somewhat inspired from Brazil buildings. During building this, I encountered the Limit of wall segments so I had to redesign the blocks thinner. The interior is empty, just 8 cheap lights per floor to take night screenshots. Made in 2013.
This is the UNFINISHED The Sims 2 replica of Peles Castle, the most expensive building of Romania. I designed it in 2007 after visiting the castle, using base game on a 5×5 lot, being distortioned to fit. I re-designed it in 2010 using Apartment Life to get 6×5 lot and roof variety, but rear facade was a blank wall.
