THE MODEL I SENT IS NOT FULLY FINISHED, I CONTINUE WORKING ON IT. IN THIS MODEL, CURVED COLUMNS OVERCOME ON THE GROUND FLOOR. THE CURVED COLUMN FROM BELOW SHOWS CONTINUITY AS FLAT UP. THE VERTICAL COLUMN FROM BELOW LOOKS CONTINUOUSLY WITH INCLINED UP, IN 3 B THE COLUMNS ON THE FLOOR FLOOR APPEAR WITHOUT BOTTOM BACKUP. I LOVE IT IF YOU ARE INTERESTED.
