3D Cell Library to 2D Cell Library maintaining the Hidden lines view

I know how to convert a 3D file to a 2D file.  What I have is a 3D cell library I need t convert to a 2D cell library and maintain the hidden line top view.

I haven't found anything on this.

I could use the help.

I imagine that this would be a very useful thing.

About 1000 cells.

 

Thanks.
