Welcome to the second Blender how to ( here is the first ), a series of quick step by step tutorials showing you how to accomplish a specific task using Blender.  Today we will look at a way of quickly modeling a high rise building.  It assumes you know the basics of using Blender.  If you don’t, no worries, I have tutorials for that!

 

First, start with the default cube, like so:

image

 

Now enter edit mode(TAB) and  loop cut (CTRL + R) it about the center, like so:

image

 

Select all the faces of the top half and separate them (P->Selection)

image

 

In object mode move the newly separated top portion up along the Z axis (G + Z + mouse)

image

 

Select the bottom box, make a copy (SHIFT + D), then move it up along the Z axis.

image

 

Select the middle piece, switch to edit mode, select the bottom face and delete it (x –> faces), like so:

image

 

This face is going to represent the various floors of your building.  Keep the top and bottom edges the same size as the top/bottom box and start carving it up to match your floor.  I generally start by doing a pair of loop cuts along the entire length, like so:

This can be accomplished by doing a loop cut (Ctrl + R), then before clicking to commit, scroll button once to perform multiple evenly spaced cuts at once.  Next I move them up and down the mesh simultaneously by simply scaling along the Z axis (S, Z, mouse move)

Now lets do several more loop cuts for windows using the same process (Ctrl + R, Mouse wheel multiple times):

Next select every other edge created (alt + shift click to select multiple) like so:

image

 

We now want to edge slide the selected edges (G,G)

image

Now select the inner faces like so:

image

Then hit E to extrude them

Repeat the similar process on all 4 sides to define your building.  Obviously you would arrange as you saw fit.

 

Now that we have our floor defined, it’s time to make a lot of them.  Switch to object mode then go to the modifiers tab and select Array:

Now we need to make sure we set the axis to array along ( set Z to 1 in the relative offset area ) and the number of times to duplicate under the count section.

image

When satisfied, click the Apply button.  Finally move your top and bottom pieces so they cap the building on each end, like so:

image

 

Select all 3 shapes and merge them together (Ctrl + J) like so:

image

Now we just need to weld our objects together.  Box select (B) the overlap area between the bottom and middle boxes in edit mode, like so:

image

Now select Remove Doubles in the Tool menu(T), then manipulate the Merge distance

image

Until you see

image 

Repeat for the top portion.

 

TADA, a building in Blender.  An ugly building mind you, but a building none the less.
