Crosshatch option as defined in swCrossHatchFilter_e

Size of array to allocate in doubles for IView::IGetPolyLinesAndCurves

Return Value

Number of lines


Call this method before calling IView::IGetPolyLinesAndCurves.




Drawing view is in any of these modes:

  • Shaded mode

  • Shaded with edges mode

  • Draft quality

This method returns 0.

Use IView::SetDisplayMode3 to change Shaded or Shaded with edges mode to Wireframe, Hidden Lines Removed (HLR), or Hidden Lines Visible (HLV), and then get the number of polylines.  

Changes are made to the parts or assemblies shown in this drawing

Polylines are only generated that are in the visible viewing bounds when the drawing is opened.

Drawing is already open

All polylines in the drawing are generated. If you open a drawing that is zoomed in to a particular region, then the polylines that are outside the zoomed region do not exist if the parts or assemblies shown in this drawing have been changed. To force the generation of all possible polyline data, call IModelDoc2::ViewZoomtofit2.
