Expand "2D Unfilled Elements".6. Change " 3 or 4 sided Polygons" to something other than "FaceEntity".7. Repeat step #6 for "3D Unfilled Elements".8. Repeat step # 6 for "Filled Elements" if these shapes are filled.9. Click Cancel.From then on, any Blocks (3 or 4 sided shapes) that are placed to a DWGformat file will match the setting chosen in the corresponding option.Note:This will not change existing elements in the file as only addedelements are processed upon DWG save or file close. If the existingelements need to b e changed, the file will need to be saved to V8format then back to DWG format, so all the elements will get processed.
