We see architectural representation as a project in itself. From the thickness of the line with which you draw your sections, to the color palette you choose. This all is part of a representation project, trying to represent beyond the lines, beyond the title text, and beyond the architecture itself.
Once an architect starts to represent their projects in a thought manner, the architecture acquires more meaning.
There is more to this than just drawing lines in autocad, or tracing and erasing stairs a million times. The architecture you create has a soul, a character, a feeling, and so does the drawings that represent this architecture. The more in tune your drawings are to your building, the better it will be read and understood.
There is no single style of representation. Don´t get carried away by trends. Study the current but also study the past, there are millions of unexplored ways to represent architecture projects, and these ways can be found in the past.
