Publish Layers to PDF from Layout
ARCHICAD 19 lets you export layouts (not just model views) with their drawing content layers to PDF format.
In the resulting PDF document, you can show or hide drawing content by layers, or navigate among layers.
Note: Layer information is exported only for visible elements within drawings - not for items placed directly on layouts.
Whether you are publishing model views or layouts, what you see is what you get.
