Very new here. Running Express before buying. Where are the Canvas settings you refer to to fix the canvas. My starting layout is linear and 2’X6’. I want to constrain my little switching yard to that. The help window doesn’t turn up anything. Thanks.
The size of the drawing canvas is fixed in our free Express edition.
For RailModeller Pro (featuring virtually unlimited canvas sizes) the Canvas tab in the app's preferences offers extended settings.
We provide additional information in the Drawing Canvas chapter in the manual and our RailModeller Express product page at https://www.railmodeller.com/express-edition-en.html
Hope this helps,
