The main Control used to display CAD models and optionally display the user interface to manipulate the CAD model. Simply place this control on a Windows.Form. Use ShowControlCenter, ShowToolBars and ShowMenu to activate or inactivate the user interface. Use ShowFile(String, String) to display a CAD file. The Frame property provides access to many more properties and methods to control the display and the menipulation of the CAD data.

Preliminary

ColorSetting is intended for objects to be used in Settings. It provides a Color with the IShowProperty interface.

Describes a movement along a curve (which may be any path or simple curve like a line)

Parameter declaration for DisplayChangedEvent.

Edge is a abstract description of an egde on a Face. An Edge may belong to one or two faces. Edges don't exist without faces (use IGeoObject and ICurvederived classes for simple 3d curves). The Edge is defined in several ways, which are overdetermined and therfore must always be in a consistent state: It is the pur 3-dimensional curve, an ICurve, and on each Face the edge is defined as a 2-dimensional curve on the surface (see Surface), which has a 2-dimensional (u/v) coordinate system (parametric space). The Edge may be an outer or an inner edge on each face or some curve on the inside of a face (typically an outlining curve for a certain Projection). The edge may not be outside of a face.

Ths setting can be displayed and modified in the control center. It is represented as a combo box. The label left of the combo box is given by the resourceId GetString(String, StringTable..::.Category), the values are

Bei der Namensänderung eines Objektes (z.B. Layer, Farbe u.s.w.) tritt diese Exception auf, wenn eine nach Namen sortierte Liste (z.B. LayerList) ein Objekt mit diesen Namen bereits enthält. Diese Exception wird in CONDOR bei Namensänderungen abgefangen und der alte Name wird wieder gesetzt.

Generic class to privide fast access to IOctTreeInsertable implementing objects.

Definition of a node of this octtree.

Klasse, die die Darstellung auf dem Bildschirm realisiert. Die Klasse hält (z.Z.) 4 Bitmaps, die nacheinander und transparent in das Fenster (genauer in das Graphics Objekt des Parameters e beim Aufruf von Compose) kopiert werden. Für jedes Bitmap gibt es ein eigenes "Invalid" Rechteck bzw. Region. Der Ablauf ist wie folgt: 1. irgend etwas ändert sich (z.B das Raster, die Markierung, ein geometrisches Objekt u.s.w.). Das muss zur Folge haben, dass InvalidateXxx für den entsprechenden Aspekt (z.B. InvalidateDrawing für die geometrischen Objekte, InvalidateSelect für die Markierung) aufgerufen wird. Die Invalid-Bereiche werden für die einzelnen Aspekte akkumuliert. Irgendwann erfolgt der Aufruf von Compose (gewöhnlich ausgelöst durch den Paint Event des Controls)Dort versucht nun diese Klasse das Bild neu zusammenzusetzten. Ist der Invalid-Bereich eines Aspektes leer, dann ist das zugehörige Bitmap aktuell, d.h. kann so verwendet werden. Wenn nicht, so muss der Bereich neu gezeichnet werden. Compose löst den RepaintXxxEvent (z.B. RepaintDrawingEvent) aus. Die Handler dieses Events (gewöhnlich nur einer) bekommen ein PaintToGDI Objekt, mit dessen Hilfe sie zeichnen können.

DEPRECATED! Do not use this class it will be removed in future versions of CADability

A handle to a Pen. Pens are retrieved with this handle from a Hashtable and are zoomed appropriately.

Summary description for PerformanceTimer.

A reference to a plane. The Plane is implemented as a struct, i.e. a value type. Sometimes it is necessary to have a parameter or member, which designates a plane but may be null (when the plane is not yet computed or not valid). This class works as an object replacement of the struct Plane.

Precision specifies the order of size of a typical model. For example two points are considered geometrically equal if their distance is less than Precision.eps. Default value for Precision.eps is 1e-6. Precision.epsa is the angular precision. Two directions are considered equal if their angular difference is less than Precision.epsa.

Use this class to temporary override the values for the precision. The best way to use this class is the C# using statement. The constructor of this class overrides the values for the global Precision. The Dispose()()() method restores the previous values.

A Project is the database CADability works on. A Project is serializable and contains one or more Models (which contain GeoObjects) lists of attributes, views and UserData. A Project is usually saved in a file.

Used as a parameter in the event RemovingFromListDelegate. When handling an appropriate event, you can prevent the object beeing removed from the list.

This class contains the information to undo a change in the project database. Undoing a change is done by reflection. So we need an object, the name of a method or a property and the parameters to use in the call. This information must be provided in the constructor. The method or property must have public access.

Surface definition of a surface defined by two curves. Both curves use the standard parameter interval from 0.0 to 1.0 The u-direction is provided by a combination of the two curves. The v parameter is defined by a line starting on the first curve and ending on the second curve. It is the surface described by a wire or rubber band synchronously moving along the two curves. the default parameter space is 0.0 to 1.0 on u and v.

A System.Windows.Forms.UserControl that is composed of a CondorCtrl and two scrollbars. It implements the scrolling on a CondorCtrl.

Settings verwaltet die verschiedensten Einstellungen zum Verhalten von CONDOR. Sie wird von DrwView und Drawing verwendet. Außerdem gibt es eine globale Instanz dieser Klasse mit der Bezeichnung GlobalSettings. Settings ist eine HashTable, die Paare der Art [Name: Wert] enthält, wobei Name ein string ist und Wert irgend ein Objekt, welches serialisierbar sein muss [Serializable()]. Auch von Anwenderseite können damit beliebige [Name: Wert] Paare eingetragen werden. Wenn CONDOR eine Einstellung sucht, so wird zuerst in der Zeichnung (Drawing), dann in der Ansicht (DrwView) und zuletzt in GlobalSettings gesucht. Die mit der Zeichnung verbundenen Einstellungen werden mit der Zeichnung gespeichert. Objekte, die das IShowProperty Interface unterstützen, werden unter den Einstellungen angezeigt und können interaktiv verändert werden. Double, int und bool Werte werden automatisch angezeigt.

Exception Klasse für die Methoden der Klasse Settings

This class is a simple System.Windows.Forms.Control derived class that implements the task to display a [!:ICondorView] implementing object (e.g. ModelView, LayoutView. You can use this class to display such a view on a System.Windows.Forms.Form. It does not contain scrollbars. If you need a control with scrollbars use the class [!:CondorScrollableCtrl]. Use the SingleDocumentFrame which already creates and connects different kind of views with one or more [!:CondorScrollableCtrl] objects.

This is the main connecting point for an interactive CADability application. Other interactive components like ControlCenter, ToolBarDockContainer, MoveableToolBar or LoadMenu(String, IFrame) have to be created with a reference to this SingleDocumentFrame.

Property page in the control center, that manages the symbols available for the project.

Exception class for the UndoFrame class

The undo/redo sytem usually exists as a member in the Project and is accessed via Undo. The project handles the menu commands "MenuId.Edit.Undo" and ""MenuId.Edit.Redo" and calls UndoLastStep()()() rsp. RedoLastStep()()(). To add a step to the undo system call AddUndoStep(ReversibleChange)

A table, that associates names with objects. Its purpose is to attach any kind of (user) information to existing CADability objects. Many objects of the CADability namespace provide a UserData property, by means of which you can connect any object to it. If the object is serializable, it will be serialized together with the CADability object. If it implements IClonable it will be cloned when the containing object is cloned. If it implements IShowProperty it will be displayed together with the object in the ControlCenter. If it implements IMultiObjectUserData it will be displayed as a common property when multiple objects are displayed in the ControlCenter

Describes a vertex of an Edge. A vertex is the start or endpoint of an edge. It connects at least two edges but can belong to any number of edges.

An angle defined in radians. The value of the angle is a double which is greater or equal to 0 and less than (and not equal) 2*pi. Via cast operators the angle seamlessly operates as a double.

An axis given by a location and a direction. There is no orientation for an x-direction or y-direction. If you need that use CoordSys Keep in mind that this is a value type. Passing a value type as a (non ref) parameter and changing it's value inside the invoked method leaves the original unchanged.

A 2-dimensional point with double x and y components. Keep in mind that this is a value type. Passing a value type as a (non ref) parameter and changing it's value inside the invoked method leaves the original unchanged.

A 3-dimensional vector with double x,y and z components. The vector is not necessary normalized. Keep in mind that this is a value type. Passing a value type as a (non ref) parameter and changing it's value inside the invoked method leaves the original unchanged.

A two dimensional vector with double x and y components. Keep in mind that this is a value type. Passing a value type as a (non ref) parameter and changing it's value inside the invoked method leaves the original unchanged.
