Edge

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.

ExplicitPCurve2D

Curve defined by 3 polynomials in one veriable ("u"), or by 4 polynoms with an additional "w" component (homogenuous coordinates). the curve may be defined piecewise: the knots array defines the intervalls for the u parameter while the polynom arrays define the curves for each intervall

PaintBuffer

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:

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.

PaintTo3D

Some static helper methods

PaintTo3DOutOfMemory

Exception which is thrown when the is not egnough memory for the 3D display driver

ParallelHelper

Parametrics

PerformanceTimer

Summary description for PerformanceTimer.

PlaneException

PlaneRef

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.

Polynom

A Polynom in multiple variables, often named x,y,z, but may be any dimension. e.g. ax³ + bx²y + cxy² +dy³ + ex² + fxy + gy² + hx + iy + j (deg(ree)==3, dim(ension)==2: (x,y))

Precision

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.

PrecisionOverride

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.

PrintToGDI

Project

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.

ProjectedCurve

A 2d curve as a projection of a 3d curve onto a surface. Sometimes it is easier to calculate points in 3d than in 2d. Then we use this as a more exact for of the curve than we get, when we approximate the curve in 2d.

ProjectedModel

ProjectException

Projection

A parallel or perspective projection which is used to convert the 3-dimensional world coordinate system to a 2-dimensional screen coordinate system or to a normalized 3-dimensional cube for the paint or rendering interface (IPaintTo3D). Contains also additional hints for the paint interface and the drawing plane.

Projection.PickArea

Class defining the span or scope in the world coordinate space defined by a axis aligned rectangle in a view or on the screen. The area defined by this object is either a rectangular prism of infinite length in the direction of the view (in case of the parallel view) or a frustum (in case of a perspective view). The pickarea is created by the GetPickSpace(Rectangle), GetPickSpace(RectangleF) or GetPickSpace(BoundingRect).

ProjectSerializationException

QuadTree<T>

RemoveFillet

RemovingFromListEventArgs

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

ReversibleChange

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.

RotationMovement

RuledSurface

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.

Schedule

ScheduleList

Settings

This class is used to give access and store information that influences global behavior of the CADability system. There is a static variable GlobalSettings. This is the only use of settings in CADability. This class behaves as a hierarchical dictionary. The keys are strings, which may have the form "mainkey.subkey" The values are objects, i.e. any kind of data. If the objects implement the IShowProperty interface they are displayed in the global setting tab of the controlcenter. There are some classes like ColorSetting, IntegerProperty, DoubleProperty, StringProperty which can be used as a setting value. If you instead simply use a double or string value the setting will be only available to programming code but not to the user in the ControlCenter.

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)

UndoStep

User

UserData

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

Vertex

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.

Axis

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.

BoundingCube

Represents a bounding cuboid, that is an extent in 3 dimensions

BoundingRect

BoundingRect is an axis oriented rectangle or a 2-dimensional bounding box. It is implemented as a "struct" (value type) so assignements always make a copy.

note

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.

GeoPoint2D

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.

GeoVector
