Change Elevations (ChaEle)

Type: Interactive Application

Changes entity elevations.

Detailed Description

Interactively changes entity elevations based on the current Z source elevation. Entities to be edited are identified by pointing at them. Elevations may be displayed in the graphics windows and many edit functions such as increment and decrement may be performed.

What is the difference between Edit Elevations and Change Elevations?

Edit Elevations drives the 3D device to the points that are occupied. Change Elevations moves the point elevation to the current input elevation when a point is occupied. Change Elevations may be more useful when editing line elevations from a 3D input device such as a stereo plotter or softcopy. Change Elevations may also be more useful when editing elevations that are a great distance from the current elevation as with lines with a zero elevation.

NOTE: The current point elevation is modified when the entity is locked onto. If the Accept key is pressed to look for another entity the change will be re-saved. If the changed is not wanted the Abandon key must be pressed. Undo may be used if an entity is accepted by mistake.

PARAMETERS

Search for Lines? (SEALIN=)

Sets the Search for Lines flag.

Search for Lines? (SEASYM=)

Sets the Search for Symbols flag.

Search for Lines? (SEATEX=)

Sets the Search for Text flag.

Text rotation mode (ROTMOD=)

Defines the mode of the rotation of the text labels. 0=Rotate the text labels to the mean line azimuth. 1=Rotate the text labels to defined angle.

Elevation increment (INC=)

Defines the elevation increment to use when incrementing and decrementing elevations.

Height of display text (HGT=)

Defines the height for elevation text labels. This parameter is entered as inches or millimeters.

Rotation of display text (ROT=)

Defines the rotation of the display text. This parameter is used if the line text rotation mode is 1 (Rotate text to defined angle).

Number of decimal places (DEC=)

Defines the number of characters to the right of the decimal point for text elevation labels.

Show elevations (SHOELE=)

Specifies whether text elevations are shown during editing. 0=No 1=Yes.

Erase elevations (EREELE=)

Specifies whether text elevations are erased after editing. 0=No 1=Yes.
