I am new on AutoCad.
 
I have a pcb program that only takes dxf with line but not polygon and polyline.
 
My dxf file has polygons and polylines.
 
Could somebody help me to convert all polygons and polylines to lines?
 
Thank you.

if you are trying to get everything into lines, just explode all.
Or am i misunderstanding what you are trying to achieve?
 
Cheers

3.4 Create Line(s) to Polygon Level of expertise required for this Chapter: IntermediateSometimes, you have lines, that form a polygon, but the system still recognizes them only as lines. You want to convert them to a polygon.1. Be sure, that all lines which form the polygon, are snapped to each other (see Chapter 2.11 on Snapping Lines).2. Load the layer with the lines into the live layer:Right-mouse > Project manager > Project manager window: Add layer > Select folder and file > Open > OK > Copy layer to live layer 3. Be aware, that all lines in the live layer will be polygonized. Therefore, it might be necessary, that you delete all other features (Select > Delete)4. Once, you have only the line of consideration for polygon formation:Right-mouse > Live layer actions > Live layer actions window: Polygon manipulation > Convert lines to polygons > OK > Convert lines to polygons window: ‘Subtract island’ and ‘Remove redundant corners’ and ‘Use left/right hand naming convention’ must be checked, Snap at 0, Style for foreground and for background can be any > OK 5. Don’t forget to save._________________________________________________Want to get-on

What program was that tutorial written for? It's certainly NOT for Autocad.Also, that is not the question that was asked. The question was, how to convert polylines to lines, not how to convert lines to a polygon.
