Hmmm...."properly" is maybe a bad word.
Any raster ( image file ) to vector conversion ususaly gives a bunch of "stuff" that you have to clean up
to suite yourself. What i was meaning by "proper" is that once you have what you want to machine , stop and think in terms of the "machining" that will be done to the piece before it is DXF'd. But again, that's was my personal
preference on using LC, and still is, when i wrote the manual. You may want to add extra lines, clamps, an offset, or whatever and named appropriately to make using LC easy or not have to use some of the tools that are available in LC.
