For DXF files, I use AutocadLT to fix problems like this. You can clean up the file, close shapes using polylines, move the origin around to a useful location, etc., then export it to a compatible version. It's fairly low cost for what it can do.
If you don't want to go that route, you can simply draw the shapes you need with copper, using the DXF file you have already imported as a template. Then use Associate Copper to combine with a terminal to get the pad size you need. I've done dozens of rotary pad designs, so it's not that hard.

PADS added Join in 9.3.1, and more origin snaps, and 9.4 expands 2D features with a better Break.
In 9.3.1 Break was really 'smash into tiny pieces', but now in 9.4.1 you can select a single corner, and break there.
( This is useful for creating PCB break-off attach tongues.)
If those 2D features are still not enough, there are free 2D packages like A9CAD and DoubleCAD that can
join and trim and extend etc on 2D lines.
Ok I do logrago pads,
I tried several free CAD software
DoubleCAD highly recommended!
1 - convert gerber to DXF using CAM350
2 - DoubleCAD to clear unnecessary parts
3 - DoubleCAD to join lines when necessary "Join Polyline"
4 - Layout Pads Import and convert Copper
Thank you very much to all,
