ArraySize

Number of lines in the view

Return Value

• in-process, unmanaged C++: Pointer to an array of doubles (see Remarks)

This method only returns lines that were sketched in this drawing view. Use IView::GetPolylines6 or IView::IGetPolylines6 to access the solid model's projected display data in this view.

Call IView::GetLineCount2 before calling this method to get the value for ArraySize.

The return value is the following array of doubles:

[ Color, LineType, LineStyleIndex, LineWidth, LayerID, LayerOverride, StartPt[3], EndPt[3], ... ]

where all data values are returned as doubles:

• 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 is 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.

• StartPt[3] = array of 3 doubles (X,Y,Z) describing the line start point.

• EndPt[3] = array of 3 doubles (X,Y,Z) describing the line end point.

This set of data repeats for each line in the view. The number of doubles returned is (lineCount * 12).

The data returned from this method is in terms of view space. If you want the data in terms of sheet space (that is, the 0,0 origin being the lower-left corner of the sheet), then combine this data with the three return values from IView::GetXForm or IView::IGetXForm.

The sheet must be visible. See ISheet::SheetFormatVisible.
