The flag “Function” is set on only in case it is necessary to create a variable-function. In this case the
expression has to be made up with the use of the notation for the arguments of function (#1, #2, #3…).
If the current document is going to be used as a fragment, then for its external variables, the assembly
variable name and/or the list “connector values”. can be also indicated in the dialog “Variable's Properties”.
What that means will be discussed in detail in the chapter “Creating assembly drawing”. The name of the
assembly variable is defined in the field of a single-named parameter, and the list of connector values – in
the dialog box “Connector values” emerging upon pressing the button [Connector values…].
The list “Connector Values…” is filled up for external variable of a document, used as a fragment
with fixing by connector. Upon inserting such fragment into an assembly, the system has to
automatically change the value of the fragment's external variable in accordance with the given
(“values”) of the indicated connector. The system selects the name of the required value of the
connector in the list “Connector values” for the external variable. Upon fixing the fragment to the
connector, the system will be first looking for the first name from the list, among the named
connector values, and if it is not found – the second name and so on.
The list of connector values may contain arbitrary number of
elements.
For creating a new element of this list, the button is used in
this window, for removing already existing element – the
button . The buttons and enable to move elements
up and down along the list (the order of the elements in the
list is set by a priority of elements in the list upon searching
for the coincidences with the connector values).
The group of parameters “Value List” enables to create and edit the list of values for a variable. If a given
variable does not have the list, then the value “No” will be specified in the drop-down menu of the given
group. For creating the list it is necessary to select from the menu the required creation method: “Text”,
“Database”, “File”, “Data”, “Materials”. More detailed description of various methods of creating the list
of variable’s values is presented below in the section “Creating List of Variable’s Values”.
After pressing [OK] the created variable appears in the list of variables.
It is recommended to use uncomplicated names for the variables in order not to write lengthy
expressions. It is a good thing to write a comment for each variable.
