The following figure shows the basic structure of a SISCAD-P command:
Figure 77: SISCAD-P Command Language
The different parts of a command must always be entered in the shown order.
- Action
Actions are the part of a CAD-command that must be entered first.
The action (CREATE, ROTATE, .. ) tells SISCAD-P what it is
to do with an element.
- Object
Objects are always entered after actions.
The object part (POINT, LINE, .. ) determines, what element
something is going to be done to.
- Characterization
Characterizations are entered after objects.
The characterization defines in which way the action is to be performed to the
object.
- Parameter
Parameters define exactly what elements are involved in the action, resp.
what additional conditions must be taken into account.
SISCAD-P distinguishes between
- mandatory parameters,
- choice parameters,
- optional parameters.
