This method is called to notify the object of an attribute that changed some of its properties. The objects returns true, if it needs to be repainted.

Returns the child with the given index. See HasChildren()()()().

Clones this GeoObject.

Copies the attributes from the given GeoObject to this GeoObject. The geometry remains unchanged.

Copies the geometrical aspects of the given GeoObject to this GeoObject. Both objects must be of the same type. The attributes are not copied.

Asks the object to enumerate all its possible snap points according to the required modes defined by the parameter.

Returns a list of I2DRepresentation objects, that represent this Geoobject in 2d according to the given projection. The returned objects will be used for display and pick purposes.

Gets a list of IShowProperty objects that represent the non geometric properties of this geoobject. This list will be used during construct actions (e.g. when interactively drawing that object) to display properties like color or layer.

Returns a bounding cube of the object. The object must fir into this cube. There may be a smaller cube that contains the object if it is to expensiv to calculate the exact cube.

Gets an attribut from the GeoObject. There are the following types (keys) of attributes predefined in CADability, which can be set with this method: "Layer": sets a Layer "ColorDef": sets a ColorDef "LineWidth": sets a LineWidth "LinePattern": sets a LinePattern "HatchStyle": sets a HatchStyle "DimensionStyle": sets a DimensionStyle "Style": sets a Style Other attributes may be provided by the user.

Gets a IShowProperty object that represents the properties of this geoobject. The result will be used to display the properties in the control center.

Determins whether this GeoObject has child objects. E.g. Block objects have children. This is necessary when the child objects have different Layers

Determins whether the GeoObject has valid data (e.g. to be added to a model). E.g. a line where the startpoint is identical to the endpoint or a circle with radius <=0.0 is considered invalid.

Returns true if this object uses the attribute in the parameter. Attributes may be CADability objects like Layer etc. or any user defined objects.

Modifies this GeoObject with the given modification operation (includes moving, rotating, reflecting, scaling etc.).

Notifies about the begin and end of a modification with the mouse

Paint the object to the 3D display machine and returns a (possibly cached) displaylist

Called before PaintTo3D, not collected in the DisplayList

This method will be called from a background thread when a higher precision displaylist is needed. The object should do all the necessary calculation to produce a display list with the required precision. The display list will later be acquired by a call to PaintTo3DList (or PaintTo3D) from the main thred because the display dirvers are not multithread enabled.

Propagates the layer and color from the owner (usually a BlockRef) to this object.

Sets an attribut to the GeoObject. There are the following types (keys) of attributes predefined in CADability, which can be set with this method: "Layer": sets a Layer "ColorDef": sets a ColorDef "LineWidth": sets a LineWidth "LinePattern": sets a LinePattern "HatchStyle": sets a HatchStyle "DimensionStyle": sets a DimensionStyle "Style": sets a Style Other attributes may be provided by the user.

When an IGeoObject changes the context that contains the lists of attributes it must replace its attributes by those given in the new context. If there are no appropriate attributes in the new context, these attributes must be included int this new context. This happens when drag and drop operations are executed or when a model is copied from one project to another project. IGeoObjectImpl contains a complete implementation regarding the attributes Style, Layer, ColorDef, LineWidth, LinePattern, HatchStyle and DimensionStyle

DEPRECATED not used any more!
