“Screen” Tab
The screen group of parameters defines the modes of
displaying linear and angular values and the means of
searching and selecting elements. These parameters do
not modify the drawing graphic elements. Rather, these
are system settings specific to the particular drawing.
Element selection. Defines element selection modes
while in drawing and editing commands. Select one of
the two modes:
All. When creating and editing elements, all existing
elements will be allowed for selection.
Visible only. When creating and editing elements, only
the visible elements will be allowed for selection. The
element visibility is determined based on element
levels and visibility intervals defined in the command “SH: Set Levels” (“Customize|Levels…”), as
well as layer configurations defined in the command “QL: Configure Layers” (“Customize|
Layers…”).
Linear Units. Defines the way of displaying linear coordinates in the information fields of
the application, as, for example, X and Y coordinates in the status bar. The parameter
does not affect the display of dimensions and other graphic elements.
168
Linear Accuracy. Defines the accuracy of displaying linear coordinates in the information fields of the
application, as, for example, X and Y coordinates in the status bar. The parameter does not affect the
display of dimensions and other graphic elements.
Angular Units. Serves the same purpose as "Linear Units", except for angular
coordinates.
Angular Accuracy. Serves the same purpose as "Linear Accuracy", except for angular coordinates.
Construction Lines:
Search. Defines the mode of selecting straight construction lines. One of two modes can
be selected, as follows:
In limits. The lines will be selected according to their length defined by the “Length”
parameter on this tab. If construction lines are displayed as finite line segments, then the nearest segment
will be selected.
Infinite. The lines will be selected as infinite lines, regardless of the “Length” parameter value on this
tab and the way of displaying the lines.
Length. Defines the way of displaying the straight construction lines. Construction lines are displayed as
either infinite lines, or finite segments bounded by their end nodes. To refresh the lines display per the
new settings, use the command “EC: Edit Construction” under the icon (use the option “Update
all Line extents” under the icon in the automenu). One can set one of the following construction line
display modes:
