Scenario: You have created a project in DesignSpark Electrical that contains sheets of different sizes (A3 and A4). Is it possible to do a PDF export while keeping the respective sheet sizes? For example page 1 A4 portrait, page 2 A3 landscape.
Answer: No. You will need to save each drawing independently and then combine them into a single book using a PDF editor (like Acrobat DC PRO, Foxit, etc.)
