I had to do something similar for a case study on Moriyama House. The advise I was given was to pick the lines that make the most sense to communicate. If it’s a section for sections sake then it’s not providing any more value or context and only serves as static.
Options I would consider are: -a series of different sections that communicate effectively. -combination section and perspective, if you can find a straight line through that works. -serial sections staged in the form of a panoramic or maybe precession depending on what needs to be highlighted.
Ultimately you should ask yourself if whatever strategy you choose is: clear, effective, informative and engaging. If it’s not you probably don’t have the right strategy for your project.
