User Information

Of course, the power of the system requires a comprehensive internal CAD data model. To keep track within SISCAD-P, the user has a lot of information at his disposal.
The most important source of information is the user-info, which may be activated with the corresponding icon in the main menu. The user may either have the requested information displayed selectively or for a special type of objects the whole range of information regarding all suitable objects. Here all information is offered by the definition of the object, its relations to other objects and its parametric constraints. In case other objects are mentioned within the info text, the user may visualize them by simply clicking the corresponding text or may have the desired information displayed. For dimensioning objects additional information is provided, because a lot of parameters directly influence the dimension image. Altogether, the user may completely survey which construction logics is saved in its construction at the moment being. This is very helpful when system reactions are not as understandable as they should be.
Within the menu parametric info there is a function SHOW (exclamation mark), which informs about the degrees of freedom of the several objects with the help of displaying the geometric elements of the active parts in color. The number of the degrees of freedom always is indicated for the part currently worked at when the corresponding menu is activated.
In addition, the system offers brief information where new data may be created. Example: with the CAD-command REMEMBER PARALLELISM all lines are displayed for which the constraint parallelism is saved. Within the calculator all functions and variables defined up to this moment are displayed. If the user tries to construct an inconsistent datamodell (e.g. with contradictional dimensions), the CAD-command is not only rejected but the objects concerned are displayed in color.
