-Most CAM applications prefer their data to be "paths"+
  
-In the case of SVGs, most vector editing applications has "to path" commands/menu items. This will convert all other entity types (splines, rects, circles, arcs, text, etc) to "paths". Path data allows the machine to "follow" the line and better calculate offsets. +Most CAM applications prefer their data to be "paths" (Not just OpenBuilds CAM, many others also work better with files that contain path/polyline type, simpler to process and import)

-==== File Versioning ====+===== File Versioning =====
  
 Especially in the case of DXFs, there are multiple versions of the DXF file standard that was released over the years. If you have trouble importing a DXF into your CAM application, a good first port of call, would be to "save-as" the file and select an older version of the DXF standard, for example, DXF R14 Polylines Especially in the case of DXFs, there are multiple versions of the DXF file standard that was released over the years.
