The current filter parameters, which are the currently active condition set, are displayed in the lower part of
the dialog. This set consists of one or several conditions joined by Boolean “OR” operator. Thus, an element
is allowed for selection if at least one of the conditions is satisfied among the current set.
Each condition in a set is written out on a separate line. It consists of limitations on the element parameter
values. The limitations are joined in a condition by Boolean “AND” operator. To satisfy a condition, the
element must comply with all and any of the limitations thereof.
To create a condition, use the main pane of the filter dialog box. This is a table of properties of all elements
in the current document. To define a limitation on the value of some parameter, checkmark this parameter in
the box before the parameter name in the table using . The limitation type for this parameter value will
automatically appear in the “Operation” column, by default, “Equal”. If necessary, change the type by
clicking on the type and selecting any other entry in the coming pull-down list, namely, “Not Equal”,
“Greater”, “Less”, “In Interval”, “Out of Interval”, “Exists”.
If the limitation type requires entering a value or values of the parameter, do this in the “Value” columns.
Thus, for “Equal”, enter a value to compare against the element parameter value. Use the first “Value”
column for this. For limitations requiring two values, as for “In Interval”, fill in both columns by entering the
starting and the ending values of the interval.
Once all limitations are defined, press the [Add] button. The just created condition will appear in the lower
pane of the dialog box. If there was already a set of conditions at the time of the new condition creation, the
latter becomes part of this set.
When creating a condition, the parameter values can be read from a specific element. To do so, checkmark
the necessary properties, and then press the [From Element] button. The dialog box will temporarily
disappear from screen, making possible selection of the desired element in the drawing window using .
Once an element is selected, the filter parameters dialog box comes back on screen. The checked parameter
values will be the same as those of the selected element.
To delete the current condition set or a part thereof, use the [Delete] button. To do so, first highlight with
one or several conditions. Then press [Delete], and those will be deleted.
