It's possible to model sloped tracks in nControl™. Supporting sloped tracks is, however, work-in-progress so there are still a number of limitations in what you can do.

The main challenge in modeling ramps is that there are no sloped LEGO® tracks. As such there are no fixed conventions and you have to define the rate of ascent/decent yourself. At the moment, slopes are only supported for the 16 stud long straight tracks and the standard R40 curves. All the other tracks are always placed horizontal but they can be used at a raised level. The video below shows how to model a layout in which the right-hand side of the track is raised by 5 bricks. Both ramps change height with 1 brick per track segment. The markers on the connection nodes represent the height expressed in bricks; the height of 1 LEGO® brick is 9.6mm or 0.38".

Modeling sloped monorail layouts is straightforward as there are sloped tracks segments to do this. When you add a lower ramp, upper ramp or ramp extension nControl™ will automatically adjust the level of the tracks. The video below shows how to model the layout of the Futuron monorail set 6770. The markers on the connection nodes represent the height expressed in bricks; the height of 1 LEGO® brick is 9.6mm or 0.38".

In some cases the tracks overlap each other and it's impossible to see the lower tracks. You can make them visible by only showing the track segments that are in between a minimal and maximal height level. You can change the height zoom bounds as follows:

• Arrow Up key: increase the minimal level with one brick
• Arrow Down key: decrease the minimal level with one brick
• Shift + Arrow Up key: increase the maximum level with one brick
• Shift + Arrow Down key: decrease the maximum level with one brick

The track segment will only be shown if the average height level of the segment is between the bounds on the height zoom. The video below illustrates the use of height zooming on the monorail layout of the Airport Shuttle, set 6399. Note that the bounds of the height zoom are shown in the task bar for a couple of seconds after they have been changed.
