Export to DXF file from Creo View is not correct. From Creo Parametric is correct. The DXF file behaves correctly. I mean this. When I set black backgroung in Autocad so I will have lines automatically white. From Creo View does not work correctly. The DXF file is not DXF file with correctly content. I think this. Color of lines is not correctly. I can not say to our customer - You must use AutoCAD with white backgroung because our DXF has black lines only. This is mistake of export do DXF file from Creo View.
