Now the cylinder will appear inside your brush. You can see the mesh through the brush.
Deselect all and delete the square brush. Now select the cylinder and press v for vertices mode. Small green and pink spots will appear. You can edit the position of these points and therefore have an influence of the shape of it. Now you can make 90° cylinders or other stuff. Depends on what you want to build.
Create a brush and activate the menu Curve -> End cap.
This kind of patch is often used in combination with jump pads like in the map The Camping Grounds (q3dm6).
Create a brush and activate the menu Curve -> Bevel.
Create a brush and activate the menu Curve -> Cone.
Some mappers use them for creating small terrains but I wouldn't. Hmm, you can give them the shape you want.
Here I use the patch mesh for a curved edge in amt-fs3.
There is a couple of caps you can use.
The pink ones show you the different types of caps.
If you tried to create the examples I described above, you have seen when creating the caps at the latest: Textures never fit when creating patches.
Now a small window appears: the surface inspector. For patches, the CAP, Set, Natural and Fit buttons are important:
Prevent players from getting stuck and make corners round with bevels.
The common/caulk texture is important!
Create a brush, activate the menu Curve -> Simple Patch Mesh (3x3) and select a texture.
