LAKLIN=	Makes a Lake Line in which the elevations of the line are set to the first point.	0 = Off 1 = On
EXPSPL=	Explode splined lines. If line mode is splined will place extra points on the line to approximate the spline curve.	0 = Off 1 = On
EXPFON=	Explode fonted lines. If the line used a non solid line font, multiple lines will be placed to generate the line font graphics.	0 = Off 1 = On
EXPSF=	Explode line scale factor	If the explode spline option is on, this controls how many points are placed on the line. 1.0 = use normal Spline chord distance. Large numbers add more points, smaller numbers add fewer points.

Splicing

It’s possible to splice the current line into another existing line. It is also possible to splice the current line into two existing lines. Parameters may be set to splice automatically based on the position of the end points of the current line. When using Insert Line for splicing, it is not necessary to set any of the line properties such as Layer and Graphic Pointer. The resulting spliced will have the properties from the existing line. If a splice is made between two existing lines, the properties for the new line will be inherited from the first existing line which is the line closest to the start point on the new line.

It is possible to inherit the elevation of the existing line when splicing by setting the Splice Inherit Z (SplInh) parameter. When this parameter is set to Yes then the elevation of the spliced line will inherit the elevation of the base line. In the case where three lines are spliced the elevation of the first line will be used. This parameter should only be used when splicing features such as contours where a constant line elevation is assumed.

Splicing is set up by turning on the splicing mode. This can be done from the Enter button (Button 7) then the Params button (Button 7). The splice search distance may be set here also. The splice flag and search distance may also be set from the Spl= and SplSea= key-ins. For example; a key-in of Spl=1 SplSea=20 would turn splicing on and set the search distance to 20 ground units. These key-ins may be placed on a Function Key so Insert Line may be started with splicing set.

The results of splicing may be undone using the Undo command.

Following are several examples of splicing:

Example 1 – Undershoot Splice

The red line is the existing line and the grey line is the new line. The end point on the new line is within the Splice Search Distance (SplSea=) of the existing line. The first point on the new line is not within the range of an existing line so this end of the line will not be spliced. This condition is considered an undershoot splice.

When the new line is ended it is spliced into the existing line. The new line inherits the properties of the existing line.

Example 2 – Overshoot Splice

The red line is the existing line and the grey line is the new line. The first point on the new line is within the Splice Search Distance (SplSea=) of the existing line. The last point on the new line is not within the range of an existing line so this end of the line will not be spliced. This condition is considered an overshoot splice.

When the new line is ended it is spliced into the existing line. The new line inherits the properties of the existing line.

Example 3 – Two Point Splice

The red line is the existing line and the grey line is the new line. Both the first point and end points on the new line are within the Splice Search Distance (SplSea=) of the existing line. This condition is considered a Two Point Splice.

When the new line is ended it is spliced into the existing line.

Example 4 – Two Line Splice

The red and green lines are existing lines and the grey line is the new lines. The first point is within the Splice Search Distance (SplSea=) of the red line and the end point is within the range of the green line. This condition is considered a Two Line Splice.

When the new line is ended it is spliced into the existing lines. Notice the spliced line assumes the line properties of the first existing line.
