GEOMETRY SPLIT line_name [point_name] position_on_line OR [point_name] /CURSOR

            

This command is used to split a line into two using the cursor.

line_name = the name of the line to be split. If not specified /CURSOR will select the line.

point_name = a name for the point created when the line is split. If an old point name is given this point will be moved to the newly defined position.

position_on_line = a real number between 0 and 1 defining the position along the line where it is to be split OR

= a cursor hit to define the position.

/CURSOR = a single cursor hit can define two actions. If the name of the line to be split has not been given in the command, then the cursor hit will select the line. The position of the cursor hit will also define where a line is to be split unless the middle mouse button is used to select the line, in which case the user can also specify the postion_on_line. (See Note 1)

Notes:

1.

Splitting definitions
The action of GEOMETRY SPLIT depends on the type of line being split.

Line Type Comments

ARC and STRAIGHT - The selected line will be split at the nearest place to the cursor hit and a new point created.

SPLINE - The selected line will be split at the nearest point on the line that is defined in the spline set.

INTERSECT - The selected line will be split at the nearest node position on the line.

2.

Naming of Split Lines
If the line is not part of a surface definition, the line segment containing the first point defined (in the original line definition ) is given the old line name. A new line is generated for the other section.

If the line is part of a surface, both halves of the original line are given new names. A line combination is defined with the original name and made up of the two new lines.

3.

Unsplitable lines
Lines defined from elements or nodes cannot be split. Lines already in line combinations can only be split if there are less than four lines in the combination. This is because any new lines formed are added to a line combination.

4.

Line divisions
The number of divisions/line is split as evenly as possible between the two new lines. The total number of divisions will remain the same. For example, if a line has 4 divisions and is split approximately half way along there will be two divisions on each of the new lines. If the same line was split about three quarters of the way along, the new lines would have one division and three divisions.
