While I recognise I have 12+ years of experience of working with ARCHICAD, the process I described is hardly expert level stuff. That said... Quick run down in simple words (I'm trying!).
You make composites or complex profiles with Building Materials by defining the thickness of the building material and type (finish, other or core) in composites or their custom shape by drawing it with the fill tool in complex profiles.
A Building Material is a sort of container of attributes. A cut Fill, a Surface and you can define physical properties and strength of the material. If you have a decent template, there should be a collection of most typical materials already.
Best practice is to duplicate something that comes close and modifying that. So if you want to make a siding Building Material, duplicate some wood Building Material and give it a logical name. You can change the Cut Fill to something appropriate. This is what is shown in plans and sections when your siding is cut.
Now for the siding to show up as something recognisable in 3D, we need a Surface. Again, your template will most likely have something that comes close, however, you can also create a new surface from a library of surfaces. I explained this above.
Duplicate (or create from the library) a new surface for your siding. You might need to change the colour or the texture image if you need a different look. Assign a vectorial fill with the proper spacing of lines. Again your template should have a few of these already, if the proper spacing is not there. Go duplicate one of the horizontal or vertical spaced out line fills and change the spacing.
If you are going to make a photorenders with Cinerender, go in to the cinerender settings as well and change the size and colour accordingly.
This might sound like a LOT of work, but it takes more time to type things out then to do them.
If you have no idea what fills, surfaces and building materials are, you need BASIC training. Ussually your local reseller will offer training. I believe our reseller (Netherlands) has a course that takes 3-4 days, after which you will know these kind of basics and a lot of things you will not learn by trying things yourself. Productivity gains far outwheigh the cost of training, in my opinion.
Alternatively:
