Define
Variables are created with the command CREATE VARIABLE. The chosen
characterization N, T resp. C defines the type of the
variable. That's important for later use.
You have to assign a value to a variable. Thereby the respective type of the
variable has to be considered again. The value assigned to a
variable is also known as the content of the variable.
It is optional to assign a name to a variable, but this should be done for any
later referencing.
Modify
With the command MODIFY VARIABLE you have the possibility to change
name and content of a variable.
Changing the content of a variable has an effect on the geometry when rule 1: save constructional relations is active during the time the variable
is used.
Delete
For the deletion of variables (DELETE VARIABLE) the same rules apply as
for the deletion of other geometrical objects. Deleted are all objects which
depend on the variable that is deleted. The same is valid for geometrical
objects for the construction of which such variables have been used and
constructional relations have been saved.
Inform
With the calculator (tool box in main menu)
you will have a quick overview of the variables used within a construction.
Detailed information is available under general info within the
main menu. There the names as well as the current contents and calculation
rules, if necessary, are displayed for all or some special variables.
