How can I use Cylinder Mapping on a complicated object? I have an object which is made up of cylinders, but all at different angles. I thought I could just do a cylinder map on each different section and set the angle of the cylinder map (Like in Maya), but it doesn't seem to have that option. I can choose 'align to object' which works as expected for the vertical cylinder section, but it won't work for the other two sections. 

How can I easily map the other sections?
The Cylindrical, Spherical and Cubic texture projections in Blender are oriented by aligning an orthographic view before executing the U unwrap command with one of the options in the window with that view.

You can have other 3D views open to keep an eye on things.

On a roughly cylindrical selection of your model you can:


Look directly across its equator, with its poles up and down. 
That's ShiftNumpad 7 with a latitude loop of edges (temporarily created and?) selected
You may have to revive the keyboard shortcut for rolling the viewport
Use options something like these:




Or you can:


Look directly down one of its poles
That's ShiftNumpad 7 with a polar face (temporarily created and?) selected
Don't forget you can H hide parts of your mesh to make these operations easier
And use options something like these:
