The quantity in the “Expression” field can be modified as
necessary. After that, exit the editor by pressing [OK]. The
drawing will instantly update per the new value of the “W”
variable.
An expression can be used for the parameter “Distance” just
in the same way. For example, suppose, the new line is
constructed on the right-hand side of the vertical line. Then,
to work around the “-” sign in the value of the variable,
the variable can be assigned the expression “-W”. Generally speaking, one can use formulas with several
variables in the expressions.
For viewing and editing the values of the variables, one can use an additional window “Variables”
which allows working with variables in transparent mode.
Editing Lines
The “EC: Edit Construction” command is provided for editing construction lines. It is one of most often
used commands. This is the command that supports creation of new drawing configurations by providing a
dialog box for varying necessary construction parameters. The command allows editing all kinds of
construction entities.
The command is called as:
Keyboard Textual Menu Icon
“Edit|Construction|2D
Construction”
To modify location of some construction entity, simply select
it using , move the cursor over the desired location, and
click again. To specify the exact value of the placement
parameter, use the property window or the parameters dialog
box via the option.
If the entity was driven by a variable, the system will output a
warning. To avoid the system warnings, call the option
before selecting any entities. A dialog box will come up, in
which the item “Auto change Variables” needs to be
checked.
When modifying the values of construction parameters it is
possible to use Relations that appear on element selection.
These Relations are temporary. They will automatically
disappear on editing finish. To modify the values of
construction parameters with the help of Relations it is
necessary to turn off “Dynamic recalculation” mode (option
, see below).
