Line Parameters
Lines
When creating and editing lines, it is often required to define various line parameters. The geometrical
parameters, such as coordinates, the distance or the angle to the related line, can be entered in transparent
mode in the property window. However, in order to define the general system parameters of the line, one has
to use the option to bring up the dialog box of all line parameters.
Distance. This is the distance between the newly constructed line and
the line selected as the reference for the construction.
Level. Places the line being created on the particular visibility level.
Levels help hiding certain elements from display. The level
parameter can be assigned a variable.
Layer. This parameter allows placing the line being created on a
certain layer.
Line length. Defines the way of construction line representation in
display. The detailed description of this parameter follows below.
The available values of this parameter, provided in the list, are:
Default (From status);
Truncated;
Infinite.
Color. This parameter defines the color used for displaying the line.
Set as default. Setting this flag means, the current parameter settings in this dialog box will be used from
now on in construction line creation, with the exception of the “Distance” parameter.
Truncated Lines
Normally, construction line entities appear on a drawing as infinite lines. However, as a drawing grows
crowded, managing it becomes difficult. A means is provided for setting shortened representation of
construction lines that allows working with lines as segments of limited length.
A trimmed, or truncated, construction line is bound by its two end nodes. The
extents of trimmed construction line overhangs can be defined in the
command “ST: Set Model Status” (the parameter “Screen|Construction
Lines|Extents”).
If a construction line does not have nodes, then it will always appear as an infinite line. If a construction line
has only one node then the “Extents” parameter should better be set greater than zero, as otherwise the line
will disappear from display.
The line display gets up to date after executing the following options of the “EC: Edit Construction”
command:
Update selected Line(s) extents
Update all Line extents
