Level Editor Dialog Box

Use this dialog box to edit the levels and gradients for feature line, plot line, or survey figure segments. You cannot change the values of the chainages or segment lengths.

Green triangles indicate primary geometry points. Green circles indicate intermediate level points.

White triangles indicate split points, where two features lines cross with neither having a geometry point at that location. Split points cannot be directly edited. When a vertex shares a point with another intersecting feature line, a small plus symbol is added to the icon for that row. The gray point icons in the grid control and the drawing glyphs represent read-only objects, such as daylight lines and dynamically linked feature lines.

Use the Shift key to select multiple rows for editing with the Raise/Lower commands.

Select Line

Selects a feature line, plot line, or survey figure for editing.

Zoom To

Zooms the drawing display to the selected intersection point (IP) or level point.

Quick Profile

Creates a quick profile of the feature line.

Raise/Lower

Adjusts the level of rows either upward or downward. If no rows are selected, prompts for a new level for the first point, then adjusts all rows by the same relative amount. If rows are selected, prompts for the new level of the first selected row, then adjusts all the selected rows by the same relative level.

Raise Incrementally

Adjusts the levels of all points upward by the increment value. If no rows are selected, the option adjusts all points, otherwise it adjusts the points only for the selected rows.

Lower Incrementally

Adjusts the levels of all points downward by the increment value. If no rows are selected, it adjusts all points, otherwise it adjusts the points for the selected rows.

Set Increment

Specifies the value to be used by the Raise and Lower commands. Enter the value.

Flatten Levels

Specifies that the levels of all selected rows are flattened to either the same level as the first row in the selection, or a constant gradient from the start level to the end level of the selection. Click to open the Flatten dialog box.

Insert Level Point

Inserts a level point between the start and end chainages of the footprint, creating an intermediate level point.

Delete Level Point

Deletes a level point between the start and end chainages of the footprint. You can delete only a single-row selection of intermediate level points.

Levels From Surface

Selects a level from a surface in the drawing. If there is only one surface, it automatically uses that surface to retrieve the levels. If there is more then one surface, it prompts you to select the desired surface. If no rows are selected, it updates the level of all points. Otherwise, it updates just the selected rows. If the feature line is off the surface, it displays a warning message. If some levels are updated, but one or more points are off the surface, it displays a message indicating the number of points off the surface that could not be assigned levels. This option is disabled if the drawing has no surfaces.

Reverse

Changes the direction of feature lines. Updates the editor so that the order of points is reversed. This command affects the labeling and chaining of feature lines.

Show Gradient Breaks Only

Displays only the feature line start/end points and any gradient breaks in between. This option simplifies the editing process by allowing level edits to span multiple points. By default, the table displays all feature line points.

Unselect All Rows

Clears any selected rows so that the Raise, Lower, and Flatten commands to affect the entire length of the footprint.

Chainage

Identifies the point that starts the current segment.

Level

Specifies the level of the point identified by the Chainage.

Length

Displays the length of the current segment.

Gradient Ahead

Specifies the end level of the current segment in the forward direction. Modifying this gradient will change the level of the segment. This is the level of the next Chainage point in the next row of the grid.

Note: To edit the gradient of multiple rows, select the desired rows and edit the gradient of one of the selected rows. The new gradient will be applied to all selected rows.

Gradient Back

Specifies the gradient of the current segment from its end to start. Modifying this gradient will change the start level of the segment, which is the point at the beginning of the current row.
