New Point Elevations - Reference

The function 'New point elevations – reference' calculates the height for a new point elevation based on the distance from the reference point and the current slope. More points can be set out, with the first point as a reference, until the function is terminated by pressing Enter. By using different options at any time at the command line, it is possible to:

• Lock the elevation. The slope changes when the distance changes.

• Change the slope value (default value is 2%)

• Lock the distance. The next point will be at a specified distance from a reference point.

• Specify the slope and the height and the distance from the reference point is calculated.

Working procedure

When the function is started, the command prompts:

Specify basepoint or [Pick Height]:

Pick the position of the new point elevation in the drawing, alternatively press ´P` and select an existing point elevation.:

Then the command prompts:

Enter height <0.0000>:

Type z-value, press <enter>

The first point elevation is now defined, by moving the cursor you will see the next point elevation and distance change in real-time, based on the set slope.

The command prompts:

Specify next point [Pick height/Elevation/SLope/Distance/Height&slope]:

Pick a position for the next point elevation, or change the settings by the following

• ´Pick height`: type ´P` - select a new point by clicking it.

• ´Elevation`: type ´E` - locks the elevation to see how the slope changes in realtime

• ´SLope`: type ´SL`- enter the new value for slope, press 'Enter'

• ´Distance``: type ´D`- enter a value for distance, press 'Enter' - a circle with a radius equal to the selected distance appears. Point out a direction to set out a new point elevation on the circle. It is possible to snap to apparent intersections (the circle and lines in the drawing). The circle is removed by option [Remove lock] - type ´R`.

• ´Height&slope`: type ´H`- specify new elevation, press 'Enter', then specify new slope value and press <enter>. A circle with a radius equal to the calculated distance appears. Point out a direction to set out a new point elevation on the circle. It is possible to snap to apparent intersections (the circle and lines in the drawing). The circle is removed by option [Remove lock] - type ´R`.Arrows point downwards onto lower heights. Press the Contol key to get a positive slope.

Tip: The next point elevation is automatically set at a lower level according to the slope (the slope arrow is pointing away from a reference point.) Switch direction by pressing Ctrl-button during set out - the next point elevation will then instead be placed at a higher level according to the slope.

About point elevations in Novapoint Terrain

• Point elevations are blocks with the insertion point in the “+”-sign. The z-value for the block will always be equal to the written text.

• It is possible to use osnap when setting out point elevations - the z-value in the specific point snapped to will show in the command prompt. To use the snapped z-value instead of typing in a value - just press 'Enter'.

• The leveling tools are a set of functions working within the dwg file as well as interacting with the active terrain model. Editing and calculating point elevations must be done by using the leveling tools only. It does not work to use AutoCAD functions like move, copy, copyclip/paste, properties, attribute editor, etc. in order to edit or manage the appearance of the point elevations

• Styles for point elevations and slope arrows can be created and managed inside New point elevations setup.
