Core

Core is basic construction stone of platform. Core provides necessary functionality for appliction. C++ is platform program language, using MFC library.

List of smaller units contained in core following:

  • 'main frame' of applic - apart from another parts it consists of parts that are important for base application window creation. The window contain MDI administrator, konfigurable menu, toolbars and property dialog.
  • projects and positions administration - insure functionality for creation, editing, rename and deleting of project and positions. User work with project, that contain several positions. Position is separate part of project (e.g. plate structure, beam, cross-section, ...), that create a unit mainly in static seeing. More positions of  same or different type can create a project. Positions communicete and change a data among themselves. By this way is possible use cross-section data (as separate position) in frameworks and reactions calculated in framewoks use as inputs for design of foundations.
  • windows administration- insure storing of work area for single projects and positions. User can create a own settings for single projects and positions, that will be applied in start of project or position.
  • property dialog - is modelles dialog of minimal necessary dimensions, varied of its content by current action. Property dialog contents necessary and optional informations for currently executed input insertion, mainly for graphical mouse inserting.

  • catalog administration - user can creates a catalogs for objects with multiple usage. Catalogs contain by user defined groups of ordered elements (materials, cross-sections ...), that are central administrated and arbitrary user can use them later in single positions.

  • output document generation - platform contains simple generator for outputs. User defines in generator look of output document and inserts to document single representations of positions (graphical or text), for that user choose a corresponding characteristics settings (scale, factors for representation of results, ...). Generator works directely with result look (see pages dividing, placement of single parts in pages ...), that is result of printing. User can inserts to result document own graphical entities and settings for later using.

  • representation view - the view is uses by all modules for representation. View contains functionality for representation, tranformations and user inputs and contains a class for representation (standard drawing via WIN API - Device Context), that assure drawing of basic graphical entities (line, circle ...). The class can be changes by another class during program running, that can be created for another kind of representation - e.g. for rendering change a class for representation by Open GL or DirectX. Also all coordinates changes are alignmented by interchangeable class of 2D transformations. The class is automaticaly changed during Draw3D module initialization to class for 3D transformations. The change allow, without compiling of arbitrary application part, not only 3D entities drawing, also 2D entities drawing in space (finded in one plane).

  • single commands - are created by single modules and central managed by command manager. The solution allow configuring menu and toolbars by user requests
  • attributes administrator  - characteristic object property is attribute (color, type of  pen, font, ...). Platform contains administrator for keeping of the properties (repeted and  multiple usage), i.e. contains functionality for attributes creation, editing, deleting and save.
  • database engine - insure all manipulations with database file for projets and positions save.
  • collections - contain lists and arrays for different types
  • basic UI classes - contain base classes for UI. Standard objects are defined for inputs inserting for Windows 95/NT.
  • mathematic and geometric functionality -  contain mathematic definitions of base graphic elements (point, vector, matrix ...), operations, tranformations and geometrical operations with simple graphic entities (intersection points of two abscissas...). Booleans operations with enclosed objects are component too.
  • grid - it is table for inputs inserting and representation of multiple informations. Separate control is aviable, control "work" in dialogs and views for application based on MFC library. Single items can be different type - edit, edit for numeric values, combobox, checkbox, list, ... . By user defined new types can be added to class. Single label (items of  vertical and horizontal header) and table items can merge through more fields, defined by table creation. Defined table is represented in output document (after transformation to graphical object) too, where it contains edit functionality too.

  • interactors - exist in cooperation with commands for inputs inserting. Interactors are objects, that take all inputs (mainly mouse) in case of given action choice. Interactors communicate with property dialog.
  • link to remote objects - platform contains links for communication between positions and positions and extern data (catalogs, other projects ...). The objects, without user influence, keep up the relations to remote objects. The functionality allows connection of single positions with data usage, connection to catalogs and at the same time updetes changes in all connections, i.e. in case of e.g. material change, position recalculation ..., the changes will be immediately carried out in positions using these data.
