Erase All command (Edit-Tools menu)

This command can be used to erase selectively the track‚s shape, objects or textures. The following track components can be deleted :

- Track shape (XY) : this option removes all turns from the track, shaping it into a large circle instead.

- Road elevations : this option removes all slopes from the track, but only affects the mean elevation of each track node : all small bumps will be kept, and the surrounding scenery retains its relative elevation.

- Scenery elevations : this option flattens the whole track 3D structure (but not the objects), setting its Z coordinate to equal that of the corresponding track node : the slopes of the track are kept, but the scenery and small bumps are flattened. When combined with the previous option, this flattens everything.

- Lanes, fences & sound sources : this option removes the miscellaneous track polygons corresponding to road lanes and fences, as well as the sound sources all over the track.

- Polygon objects & light sources : this option removes all polygon objects (displayed in blue), as well as the light sources.

- Extra objects : this option removes all extra objects (displayed in green) ; the global animated objects are not affected.

- Global animated objects : this option removes all global animated objects from the track (not displayed by T3ED). If this option is enabled, then it will not be possible to undo the changes ; making a backup copy of the track is therefore recommended.

- Road textures : this option sets the textures of all passable road polygons to a given value (modifiable using the corresponding input box and Browse button). This also affects low- and medium-resolution polygons, although the heuristics for guessing their passable or non-passable state sometimes fail.

- Scenery textures : this option sets the textures of all non-passable road polygons to a given value (modifiable using the corresponding input box and Browse button). This also affects low- and medium-resolution polygons, although the heuristics for guessing their passable or non-passable state sometimes fail. The objects are not affected.

Combining all these options, it is possible to remove virtually everything from a track, making it possible to restart almost from scratch.
