Figure 31: CAD Command Window
In this window, you can select CAD-commands by clicking the corresponding icons
and fields. The icons of the current commands are marked yellow, and the
command itself is displayed in the command line of the graphic window.
The online help gives an extensive description of the CAD-commands, which
are made from the syntactic elements action, Object,
characterization and parameter.
The meaning of the remaining fields and icons is described hereafter.
- 1
- Backwards arrow-icon
Cancels the last part of a command input.
This icon corresponds to the
-key on your keyboard.
- 2
- Flash-icon
Cancels the last command input.
This icon corresponds to the
-key on your keyboard.
- 3
- Keyboard-icon
Clicking this symbol generates three keyboard windows that are
used with the help of mouse clicks; their use can be combined with the use
of the keyboard. (see figure)
Particularly the input of special characters is simplified.

- Actions
Actions are permanently displayed. To display a list of all possible
actions, click the caption commands. If you then click the desired action,
it is included in the displayed list of 8 actions. The least used action in
that list is erased.
- -
- Objects
Display of all objects. Only one object can be active (activate
by clicking!) at a time. The active object icon has a yellow background.
Clicking the symbol objects displays a sub-menu. Using this sub-menu, you
can decide what objects the CAD-commands should act upon.
- -
- Characterizations
The possible characterizations for the active object are listed here. Selection
of a characterization provides a closer definition for the desired action.
- -
- Parameter
Possible parameters for the selected command are listed here. Parameters
define how exactly an element is to be created. SISCAD-P knows three types of
parameters: mandatory parameters, choice parameters and optional parameters.
As the mandatory parameter must always be entered, and as also at least one of
the choice parameters must also be entered, they are framed in red to
distinguish them from the optional parameters.
Activating a parameter often displays a menu that helps input. In any case,
however, you are displayed the corresponding help text in the online help window
if that is open.
