Creating a layout
In LoDi-Aura, your model railway is a layout: it holds the track plan, devices, locos and trains. Create the layout before you add devices – a new layout starts empty, without any devices.
Step by step
- New layoutUnder “System” › “Project”, click “New layout…” in the “My layouts” card. The “Create new layout” dialog opens.
- NameEnter a name under “Layout name”. Each name can only exist once; if it is already taken, the dialog asks for another one.
- GaugeChoose the “Gauge”, e.g. “H0 · 1:87”. LoDi-Aura uses it to convert km/h into cm/s.
- Online backupIf you are signed in, “Back up this layout online” appears below, ticked by default: a version is saved to your Lokstore account right when you create the layout and every time you close it.
- CreateClick “Create”. The name of the new layout then appears in the header.
Setting lengths and speed
“System” › “Track plan” holds the basic settings of the layout. To begin with, three cards matter.
- Check the scaleIn the “Scale & size” card, check that “Track gauge / scale” is correct. It is taken from the dialog. Below it you can see what this means, e.g. “Scale 1:87 — 40 km/h prototype ≙ 12.8 cm/s on the layout”.
- Default block lengthEnter the “Default block length” (default 200 cm): the length a block uses as long as you don't give it its own.
- UnitsChoose whether LoDi-Aura shows lengths in centimetres or millimetres – or “US — inches (in) and mph”. This only affects the display; calculations always use cm and km/h.
In the “Turnouts” card, enter the “Turnout length” – it applies to every turnout without its own dimension. The “Turnout travel time” is the time a motor needs to throw; only after that does a route count as set. How the turnouts are set when the command station connects and after use is explained in Turnouts and signals.
In the “Speed defaults” card you set the speed of the layout: “Layout (km/h)”, “Station (km/h)” and “Hp2 · slow speed (km/h)”. The defaults are fine to begin with.
All basic settings are explained in Project and backup.
Already have a layout?
You open an existing layout under “System” › “Project” in the “My layouts” card. You bring in a backup or a layout from another computer via “Import & export”. How that works is described under Project and backup.
