NAM Documentation

There are two attributes associated with every RHW network: height and width. Transitions allow one to raise or lower the height of a given network, via Height Transitions, or to change its width, in increments of one lane (per carriageway), through Width Transitions.

Height Transitions

There are two types of RHW Height Transitions included, the FLEX Height Transitions (or FLEX-HT) and the Puzzle Piece Height Transitions. The FLEX Height Transitions are the preferred method, and are capable of producing transitions between all height levels of all widths of RHW. The Puzzle Piece Height Transitions are deprecated, include a limited number of transitions built to outmoded RHW specifications, and are not installed by default. Instead, the "Deprecated Height Transitions" option must be checked in a custom installation of the NAM. All transitions included of types are orthogonal-only; there is no diagonal support for Height Transitions at present.

FLEX Height

There are a total of 5 items under the FLEXHeight Button:

  1. 1-Level FLEX On-Slope Transition
  2. 1-Level FLEX Height Transition
  3. 2-Level FLEX On-Slope Transition
  4. 2-Level FLEX Height Transition
  5. MIS 1-Level 180-Degree Loop Transition

On-Slope versions are designed for placement at the edge of an embankment, while the standard versions are intended for placement on (relatively) flat terrain.

While each of these FLEX Height Transitions initially comes out looking like it is intended for the RHW-2 network, because they are FLEX items, they are capable of accepting overrides, and can be transformed to fit any other RHW network as needed.

Width Transitions

At present, the Width Transition options have not received the FLEX treatment. Thus, they all still exist as static puzzle pieces, designed for connecting one RHW network to another with one more or one less lane per carriageway. To use these transitions, simply drag the two networks you wish to transition between to a point where they nearly (but do not quite) meet, and place the transition. All of these transitions are orthogonal-only; there is no diagonal support for Width Transitions at present.

There are a total of 30 items under the Width Transitions button.
