Build your 3D scene using
the same CAD that was used for modelling in LEGION Model Builder or Evac.
If a model is multi-level,
the CAD levels must be separated for vertical circulation objects to work
properly in
LEGION 3D.
Ensure that the CAD you
import into the third-party 3D software is centred on the same coordinates as
the Model Builder CAD and uses the same units of measurement.
This will save time when
matching the 3D scene to the accessible space within the .res or .ora file you
will be using in
LEGION 3D.
Keep 3D objects in your
scene as ‘components’ or ‘meshes’. This will make them easier to manipulate in
LEGION 3D and may help to keep the number
of polygons within the file export limit of 64,000 polygons per object.
Apply colours and textures
as required. When using textures, store them in the same folder as exported
.3ds files and name them using the 8.3 convention (eight naming characters and
three extension characters).
If you want shadows and
lighting effects in your scene, you may find it best to apply these effects in
your third-party software and then ‘Render to Texture’ (or ‘bake’) the scene
before exporting the .3ds file.
For any pre-prepared
animations (such as the arrival of a train at a platform) you will need to
create the animation in third-party 3D modelling software.
Create .res and/or .ora
files using LEGION Model Builder.
