Edit Line (EdiLin)

Type: Interactive Application

Interactively edits a line in a VrOne workspace.

Entity Elevations When Editing in 2D

When editing using a two dimensional device such as the system mouse, there are two parameters that control the assignment of the elevation during a move line, copy line, move line points, copy line point, and snap operation. Z Mode Move may be set to “hold” the original elevation or set the elevation to the “Active Z”. Z Mode Snap may be set to “hold” the original elevation, set the elevation to the “Active Z”, or “Snap” when snapping the current symbol entity to an existing entity.

When moving or inserting a line point, only that point elevation is changed. When moving or copying a line, all the line points are shifted in relation to the current line point.

Parameters

Z Mode Move (ZMOMOV=)

When using a two dimensional input device such as the system mouse, this parameter controls the elevation of the line or line point when moving or copying a line or line point. Option 0 is “hold”, which maintains the original elevation; option 1 is “Active Z”, which sets the elevation or the line or line point to the currently set Active Z.

Z Mode Snap (ZMOSNA=)

When using a two dimensional input device such as the system mouse, this parameter controls the elevation of the line or line point when moving or copying the line or line point then snapping it to an existing entity. Option 0 is “hold”, which maintains the original elevation. Option 1 is “Active Z”, which sets the line or line point elevation to the currently set Active Z . Option 2 sets the elevation of the line or line point to that of the entity to which the line or line point was snapped.

Inherit Function Key Parameters (FKEY=)

Changes symbol parameters to the parameters in a function key.

Z Mode (ZMODE=)

This parameter is used in the Keyboard Change (button 7) option after a line has been identified. Determines which points on the current line will have their elevation modified.

0 - Change Point (ZMODE=0) - The Elevation is applied to the current point only.

1 - Change line (ZMODE=1) - The Elevation is applied to all the points on the current line.

Z Operator (ZOPER=)

This parameter is used in the Keyboard Change (button 7) option after a line has been identified. Determines how the Elevation will be applied to the line point(s).

0 - Equals (ZOPER=0) - The elevation(s) will be set to the Elevation specified

1 - Add (ZOPER=1) - The elevation will be added to the current line point elevation(s)

2 - Subtract (ZOPER=2) - The elevation will be subtracted from the current line point elevation(s)

3 - Multiply (ZOPER=3) - The current line elevation point(s) will be multiplied by the Elevation specified

4 - Divide (ZOPER=4) - The current line elevation point(s) will be divided by the Elevation specified. If this option is active then the Elevation specified cannot be zero.

3	Rotate line	Rotates the line about the current point.
4	Copy line	Copies the line.
5	Mirror	Mirrors the line.
6	Delete arc flags	Deletes all arc flags on the line.

Copy Line Notes:

When copying a line, the elevation of the current line point will be moved to the Active Z if the input Active Digitizer is XYZ (Stereo plotter). If the Active Digitizer is XY (Digitizing tablet) or mouse, the elevations are not changed.
