Creating BTS Fans
Introduction
This page will show you how to create fans.

Base Shape
Create a 128w*128l*128h
cylinder with 24 sides with the nodraw
texture.
Create a 128w*128l*128h
Brush with the nodraw
texture.
As painful and time consuming as it sounds, using the clipping tool to make the precise shape, don't use the carve tool.
The cylinder is used to match up the vertices so make a precise brush. Use the cylinder for your guide.

Turn your shape into a func_detail and put nodraw on all of sides except for below. Just make the side brushes 128 units high.
Details
Create a 32w*32l*16h cylinder with 12 sides with the nodraw texture. Texture every side except for the top with citadel_metalwall074a
Create 2 4w*52l*12h cylinder with 12 sides with the nodraw texture. Texture every side except for the top with citadel_metalwall074a
. Center this brush with the cylinder and then copy and paste this brush on the other side. Rotate this brush so it fits on the other sides as well.
Select all of those brushes and then make it a func_detail.
Extra Details
Create a 128w*128l*8h
arch with 24 sides with nodraw.
Enter the following Properties: Wall Width: 4 Number of Sides: 24 Arc: 360
Now create the brush.
Make this a func_detail
Texture everyside except for the top part and the unseeable with citadel_metalwall074a
.
