By default, the Drawing Layout page is set to Portrait orientation.
However, you can easily change it to Horizontal if needed.
1. Open the Drawing Layout
It is important that the Drawing Layout is actually open before accessing its print settings.
Otherwise, you may end up changing the default Design Flex print settings instead of the Drawing Layout settings.
2. Go to File → Print → Page Setup
With the Drawing Layout open, navigate to the Page Setup.
3. Change the Orientation to Landscape
In the Page Setup window:
Locate the Orientation section
Select Landscape
Click OK to apply the changes
Tip: You can also modify other Drawing Layout print settings in this same window, such as paper size and title block placement.
