Hello everyone,

I'm a new user regarding CAD software and really never worked before with one. In this case what I want to do is to take a dxf file which was created by exporting data from another software in which i designed a printed circuit board.

The thing is that the 2 layers that were exported (1. copper wiring and 2. substrate background) are represented by the same color of lines and filling (white), and what i need to do is to change the filling color of the substrate layer to black so when I print it, it would appear like a negative image of my design.

I've tried in several ways to change the background or filling color for that layer but nothing seems to work, I would appreciate a step by step help if possible.

Thanks so much for it
