Could someone give me a proportions guide?, it's to make a 3D model and import it into Open Rails

Hi,

Which 3d modelling tool are you using? If you are using Blender, for instance, the Blender measurement units get translated into OR as Metres automatically.

However, metres are *default* and you might have tried to open a drawing file that used Imperial units (Those Americans... at it again)... in which case, you would need to scale the imported object by 0.3048 as we used to do with 3D Canvas/Crafter or `S 0.3048` in Blender.

Or in Blender Python

import bpy

# Set the desired metric scale factor (1 foot = 0.3054 meters)

scale_factor = 0.3054

# Set the units to metric
bpy.context.scene.unit_settings.system = 'METRIC'
bpy.context.scene.unit_settings.scale_length = scale_factor

# Iterate through all objects in the scene
for obj in bpy.data.objects:
    if obj.type == 'MESH':
        # Scale each object by the scale factor
        obj.scale.x *= scale_factor
        obj.scale.y *= scale_factor
        obj.scale.z *= scale_factor

# Update the scene to reflect the changes
bpy.context.view_layer.update()

# Print a message to confirm the conversion
print("Converted all objects to metric measurements.")
