Context of DG Kernel Components

Component Context is a set of non-essential properties described below

Property Description Type Parameter ID Default
Context Menu Determines whether popup menu appears on right-mouse clicks Boolean 0 True
Background Type Determines whether the component can have gradient background (value 1) or default flat background (value 0) Integer 0 0
UnitsString If not empty, the string will be appended with a preceding space to text of measurements String 0 Empty string
MeasurementDigits Number of digits displayed in text of measurements. Valid range: 0 to 10 Integer 1 4
SnapLineDistance If selected point in measurements is close than this value (pixels) to a line, it will be snapped to the line. Valid range: 1 to 20. Integer 3 7
SnapPointDistance If selected point in measurements is close than this value (pixels) to a point or a corner, it will be snapped to it. Valid range: 1 to 25. Integer 2 5
UseClipboard When this property is true result of some item selections are copied to clipboard in addition to any standard output relevant to the operation. See Point Measurement for more details. Boolean 1 True
ClosedSurfaceHint Notifies the component that all objects with surface following this call are expected to be solid 3D objects. The component will perform quick check that the surface is actually closed to detect input errors. If the surface of an object was not closed the component will perform operations were possible using more reliable but slower methods Boolean 2 False
Dump Used in special builds only. When set to true the component will write file(s) with additional information for tracing / debugging. Boolean 3 False
MouseStrokeColor Modifies the current color of mouse strokes (for cut surface and similar operations). Use IKCContext2 as described below Color 0 (1.0, 0.5, 0, 0, 1) (red)
MeasurementsShowOnMouseMove If true in measurements mode distance in screen plane will be displayed during mouse movements Boolean 4 False
WantSelectionEvent When true the component raises event to notify application about multiple selection of items in Direct User Access mode Boolean 5 False
GridDefaultInteractive If true measurement grid created with Ctrl + Grid context menu command will be interactively rotated during the first mouse stroke Boolean 7 False
GridDefaultUseMeasuredAngle If true measurement grid created with Ctrl + Grid context menu command will be rotated by the last measured angle Boolean 9 False
MeasurementsStyle Default Measurement Style 0- Persistent, 1 - Transient Integer 4 0
AngleMeasurementContext Properties of angle measurements. Use GetView() > IContext_DG > Get(0) > object (or IUnknown) > IContext_DG to access. See more details at Angle Measurements IContext_DG 0 null
ExplorerSelectionNotify When this property is true the component will raise ExplorerSelection event when selection in Model Explorer is changed by the user Boolean 10 False
MeshModsAutoUpdateLimit0 Lower limit for full mesh update in IMesh_DG.End(eMeshActionNormalsAuto) in microseconds. The default is 10000 (10 seconds) Integer 5 10000
MeshModsAutoUpdateLimit1 Lower limit for eMeshActionNormalsMedium mesh update algorithm in IMesh_DG.End(eMeshActionNormalsAuto) in microseconds. The default is 30000 (30 seconds) Integer 6 30000
ModelStaticOnResize Objects do not move relative to the whole computer screen dirung runtime window resizing Boolean 13 False
SelectionFastApproximation When true, for performance selection uses only bounding objects to identify the entity under the mouse, instead of the precise surface Boolean 15 False
BoundingBoxVisibleObjOnly When true, the algorithm which calculates the initial zoom and fitting scene into the view on Fit command ignores invisible objects Boolean 17 False
EnableHiddenLabelRemoval If true 3D labels geometrically obscured by some objects are not displayed. Affects rendering performance Boolean 18 False
ShowAxesIcon Show/hide the 3D global axes icon at the left bottom corner of DGAX window. Affects rendering performance Boolean 19 False
DeviationFactor Allows adjustment of the deviation calculated at runtime by triangulation algorithm for surface presentation. Reducing makes surfaces to be presented with finer mesh at some performance cost. Increasing can improve performance at the cost of surface quality reduction Double 0 1.0
WireColor Shared/global per view color used to render mesh wireframe and iso curves Color 4 Black
PointLocationTolerance Tolerance used in IMetrics_DG.GetPointLocation() Double 1 1e-8

To access the properties, query IContext_DG from IView_DG with a query: Component > GetView > IView_DG > IContext_DG and use appropriate interface as described in the above table.
