First Step – Shape

I used Metaball to find the shape I was looking for my design.

Set the points and used Gene Pool to define the volume of each point I set.

This comand (Gene Pool) alows to manipulate the shape and get an infinity of possibilities.

Of course this volume will only be seen after I set more planes wich I did using

Linear Array, setting an XY plane to define the geometry I wanted as base,

then the direction which was the Unit Z and finally the Number slider with the

amount of levels I was looking  for.   Because  I  was  going  to  need  the  lines  that

define the  shape, I conected  the  metaball to a  curve wich is going to be used to

do the rest of the details of the building.


Second Step – Slabs

Using ShiftList, ading the value and a Boolean Toggle (negative) I deleted the curves

didn’t want from the list, wich in this case was the groundfloor curves on which I didn’t

entend to create slabs. After that, I used Bondary Surfaces to transforme into

surfaces what before were just curves. Then  Extrude  the  surfaces  to

  give  thickness  and  create  the  slabs, setting a direction (unit Z) and a value.


Third Step –  window frames

Again with Shift List I separated the curves because the ground floor

needed to have a different source to extrude both windows and window frames.

when we add a value it deletes from the list from the last to the first curve, so I needed

to create to different one where in the list input would be Reversed.

To define the window frames I used Offset to set the position for both windows

and window frames. But as the offset sometimes fails to create a full polyline,

I used Rebuild Curve so there wouldn’t be any small segments wich can make the

offset no to work. After that I Used a Divide Length to create points, with 3

meters of distance (Length) from each other on every curve of wich level I chose,

connected to a line that to define the end I used Move to send those points created

3 meters down. After that transform them into Pipes.


Fourth Step – Glass

Still coming from the Offset created, I  Extrude  them 3 meters down,

that’s why I applied a negative to the value. Only the ground level was

extruded up instead because it had a different source in order to separate this

floor and create a path under the building, after this using Custom Preview

and setting a color I got the window appearance.


Fifth Step – Guards

Again using Shift List I separated which levels I wanted to have guards.

After that  I  move  up  the   curves  to  create  the  horizontal  guards,

setting   again   the   Unit   Z  and attributing a value.  And then

transforme  this curves in pipes.  To do the structure of this guards,

the vertical ones, I had to move the  curves   1  meter  high  so  they

start  above  the  slab,   then  used  the  Devide Length to create points

in the curves, this time with 9 meters  of distance from each other.

Then I move the points 1 meter  high  and unify them with a line,

and then transforme into Pipe.


This way I create this building with potential for large equipment such as

malls,  hotels,  corporate  offices.  With an organic form where the heights

flow along the building.
