I assume you have the pro version as that is required offsetting.
Setup provides posting options so see where the file is being saved.
You open dxf, clean it, create an offset based on a defined tool, go to project and un-enable that which you don't want code posted for,
in layer select the tool you want and fill in cut inputs applying them to the layers. The graphics area should portray what you desired.
Now post code.
All in the Manual / Tutorials.......,
