GetSplines2 Method (ISketchBlockDefinition)

Gets the spline points by tessellation instead of by interpolation as is done by ISketchBlockDefinition::GetSplinesInterpolate and ISketchBlockDefinition::IGetSplinesInterpolate.

.NET Syntax

Visual Basic (Declaration) 
Function GetSplines2() As Object
Visual Basic (Usage) 
Dim instance As ISketchBlockDefinition
Dim value As Object
 
value = instance.GetSplines2()
C# 
object GetSplines2()
C++/CLI 
Object^ GetSplines2(); 

Return Value

Array of doubles (see Remarks)

Remarks

Format of return values is an array of doubles with the format:

 

[ [ Color, LineType, LineStyleIndex, LineWidth, LayerID, LayerOverride, NumSplinePoints, [x,y,z] ] ]

 

where:

  • Color = COLORREF returned as an integer. Return value could be 0 or -1 for default color.

  • LineType = line type. Valid returns as defined in swLineTypes_e. A lineType is a combination of a lineStyle and lineWeight.

  • LineStyleIndex = line style. Valid line styles as defined in swLineStyles_e.

  • LineWidth = integer value defining the line width. Valid width values as defined in swLineWeights_e.

  • LayerID = integer value indicating which layer holds this entity. Obtain the ILayer object by passing this integer value to ILayerMgr::GetLayerById or ILayerMgr::IGetLayerById.

  • LayerOverride = integer with bit flags set to determine which properties, if any, have been overridden with respect to the Layer default properties.

    If the bit value is set, then the specific property or properties have been overridden. The bit indicators are: color = 0x1, style = 0x2, and width = 0x4. Therefore, if LayerOverride was returned as 3, you know the color and style have been specifically set for this item and may not match the default values associated with this item's layer.

This complete set of data repeats itself for each spline found in the sketch block definition. For each spline, the array returned contains the color, line type, number of spline points in the spline, and X,Y,Z value for each of those points. Therefore, the [x,y,z] parameter is an array of NumSplinePoints, which can vary in size from spline to spline.

 

The [x,y,z] points for each spline are not the same as the points used to generate the spline. This method tessellates the spline based on the display quality and place points along the spline appropriately.
