Add option in PDF export to convert shaded graphics to shaded VECTOR graphic objects, NOT only raster pics

Currently PDF export in Creo Parametric saves all shaded graphics in raster.

For DRAWINGs, to get "shaded" PDFs with VECTOR graphics, you need to set to non-shaded view displays (ie: NO HIDDEN) and manually fill (Layout>>Hatch/Fill) and color individual feature surfaces one by one. This is tedious and time consuming.

There should be an export OPTION to directly convert shaded views (in ALL modes; ie: ASSEMBLY, PART and DRAWING) into VECTOR graphics with shaded/rendered areas as distinct FILLED OBJECTS in the assigned part colors with lighting gradients.

Furthermore, this vectorizing option should be given to all vector capable export formats (eg: *.DWG) and more vector graphics export formats should also be added (eg: *.ai from Adobe Illustrator).
