Fusion 360 dxf files which contain objects that are composed of 3 or more straight lines such as triangle, rectangle, polygon…. will create an undesired action when Imported into Lightburn. The undesired action will manifest itself when multiple passes are employed in cutting/engraving these objects. The multiple passes will be accomplished for each segment of object before laser scan moves onto next segment, instead of making complete scan around perimeter for each pass. The  
resolution is rather simple,

. select all objects

. delete duplicates

. upgroup selection

. from edit menu, select open shapes

. from edit menu, auto-join selected shapes

. problem resolved
