Prior versions would save merged PDF files, created by AutoCAD, and not rotate landscape pages when "None" was selected at Auto Rotate. Since 8.5 they rotate randomly after saving no matter what setting I choose. I can't find a page to download previous Creator versions.
Randomly or is there a pattern?
Older versions can be downloaded that way:
https://stx.pdf24.org/products/pdf-creator/download/pdf24-creator-8.6.1.exe
The version number at the end can be changed to download a specific version.
Most of the time the first page stays landscape the rest go portrait, but not always. I read it rotates depending on text orientation, our drawings have text that's both horizontal and vertical but that never used to matter, and I use None for Auto Rotate.
Had to go back to Creator 8.4.0 to stop mixed page rotations.
