Polygon Elevation (PolEle)

Type: Batch application

 

Changes elevation of symbols and points inside a polygon or group of polygons.  This operation may be performed on the points or symbols in a single polygon by identifying the baseline polygon or a group baseline polygons in an interactive batch mode.

Detailed Description

This interactive batch application can be used to change the elevations of all symbols and (or) VrPoints (LiDAR) that fall within a baseline polygon to a single elevation. A baseline polygon is selected, and all points that fall within the polygon and meet the search criteria are changed to the new elevation.

 

This application can be applied to multiple workspaces, multiple layers, and multiple symbol graphics pointers.

 

Layers that are turned off will not be considered.

Parameters for Polygon Elevation

PolygonElevation_image006

Workspaces to consider

Defines the workspaces to consider. Options are Current only or All open workspaces.

Process symbols?

Defines if symbols should be processed

Process points

Defines if points should be processed.

Elevation mode

Defines the mode to determine the elevation to set the symbols and (or) points to that fall within the baseline polygon or polygons.  Options are:

Use New Elevation - Use the user defined elevation specified by the New Elevation field.
Use mean Z from baseline - Use the mean of  the elevations from the points that define the baseline polygon.
Use low Z from baseline - Use the lowest elevation from the points that define the baseline polygon.
Use high Z from baseline - Use the highest elevation from the points that define the baseline polygon.

Symbol Graphic Pointers to search

Defines the graphic pointers to consider when searching for symbols. This parameter may be entered as a number line.

Layers containing the base lines (batch)

Defines the layers in which to search form baseline polygons.  This parameter is used only when running Polygon Elevation in batch mode.  This parameter is entered as a number line.
