A simplified bullhead rail section is used programmatically in Plug Track. This is how it is dimensioned:
The data is stored internally in equivalent full-size prototype inches. When shown in the custom dimensioning dialog above it is converted to model mm at the current model scale set on the control template. It is important therefore to have set your model scale before entering your rail section measurements in mm.
"Programmatic" means that the data will be rescaled to the current model scale. So a 7mm/ft scale rail will appear scaled down if specified for 4mm/ft track, for example. This is important if you will be using rail from a different scale for narrow-gauge, light railways, etc. Set the actual model scale you are using, and enter the actual measurements of the rail as a custom setting. Do not click one of the pre-set rail sizes.
n.b. If the rail head width B does not match the template setting at real > rails > rail section data ... , the template will be modified accordingly and rebuilt before being exported in DXF/STL files. Take care to enter a sensible dimension for B otherwise your templates may become unusable. You may want to save a backup BOX file before experimenting.
cheers,
Martin.
