This is a collection of architectural illustrations and visualizations centered around more technical images - cut sections in perspective, details and so on.
One of my longstanding contentions is that many architectural illustrations and drawings can be significantly enhanced by being developed and designed in 3D, and presented that way; although it's true that orthographic views are easier to design, their downfall is that they far too often confuse, or simplify in a misleading way.
Although the tools I use for this are mostly pretty modern, this approach of generating perspectives, perspective sections, and perspective or isometric details and so on goes back not only to recent manual techniques, but to historical architectural practice: Fillipo Brunelleschi used them to convey his complex dome support ideas, Marcus Vitruvius used perspectives extensively, and more recently via manual drafting Paul Rudolf made extensive use of perspective sections in the 1970s.
