Hi there, in the new 2027 version of LayOut on mac we now have the “Create PDF layers from LayOut layers” checkbox, but… it doesn’t work (at least for me). Is that a known issue?
Historically Mac seems to have an issue with display of PDFs where layers are turned OFF, instead it displays as all layers as ON. I always had to send PDFs (windows generated) to clients on Mac with instructions on layers to turn off!
On Mac, Preview often does not list PDF optional-content layers, so the new checkbox can look like it did nothing. Open the same file in Adobe Acrobat and check the Layers panel before treating the export as broken. A SketchUp viewport set to raster or hybrid usually comes through as one image and will not split with the LayOut layers; vector viewports follow those layers more reliably. A layer set not to print is also left out of the PDF even when the checkbox is on.
