Hi, it seems that reproducing the exact DXF layout may be more difficult than what I have thought. > > This introduces an item on my dxf wish list.

IMHO, OpenJUMP has the great advantage to be able to manage heterogeneous layers, and this capability must be used to preserve imported file structure as close as possible to the source one (DXF, MIF/MID) . Dispatching features in different layers according to their geometry (or to an attribute value) is a generic need which should be developped in a separate plugin (not included in the driver). A plugin already exists to select features with a specific geometry type. Developping another one to create a layer by geometry type should not be too hard. For DXF layers, I must admit that dispatching features from different DXF layers into different OpenJUMP layers should take place in the driver. It is just a bit more work to load features from a single file into several layers. On the other hand, dispatching loaded features using an attribute value is also an easy thing, and I already developped a plugin to do that (this can also be considered as a generic function, and can be useful in other situations).
