Hi,
1) Some information about my dxf plugin.
It has basic capabilities and can read the following entities :
- POINT
- TEXT (as a point + a attribute containing the text)
- LINE (as a polyline made of 2 points)
- POLYLINE (as a polyline or a polygon)
The policy I used to differenciate polyline and polygon is not based on
the geometry itself (first point = last point) but on a DXF boolean flag
indicating if polyline must be closed or not.
The jump layer is created with some default attributes representing
common DXF tags like LAYER, TEXT (useful for TEXT entities), COLOR...
ENTITIES which are inside a block are read as if they were outside this
block (as simple entities)
Entities like SOLID, SPLINE, LWPOLYLINE, 3DFACE... are simply ignored.
2) best practise
As larry said, a good idea is to convert your dxf file into R12 dxf
version with your favorite cad soft before you try to import it into jump.
If it is not enough, you can send me your (small) dxf so I can have a look.
3) other dxf plugin
There is another dxf plugin made available on this list recently.
I had a quick try. It is much faster and it has more features than mine.
It is based on the following library (http://caff.de/dxfviewer/index.shtml)
It is available from the wiki : http://openjump.org/wiki/show/Plugins
Hope that helps

Nadine,
Michael Michaud may be able to clarify this for us, as he wrote the
DXF plug-in for OpenJUMP. I think the problem you are having with your
import of polygons is the way AutoCAD represents "polygons". For
example, in most AutoCAD flavors a polygon is simply a closed polyline
entity. In something like AutoCAD Map there is an acutal "polygon"
entity.
I don't think the DXF plug-in for OpenJUMP recognizes closed polylines
as polygons. Hopefully someone else can confirm this.
If it does not recognize closed polylines as polygons, you maybe be
able to inport the DXF file as LineStrings and then use one of
OpenJUMP other tools to convert them to polygons.
