Bended Columns

If you want to build a series of these objects for a
power plant or maybe an overhang connecting to
a roof,  just use the cloning tool.  Simply hit the 
space bar while the brush is selected and an exact
duplicate will appear.  Move the duplicate into place
and just repeat until you have the number you want.

   

Save, compile, and launch the game.  Not bad!
There are a whole variety of objects that you
can build with this basic object.
