.dxf files on their own cannot be dragged and dropped into our CAD software
However, We will gladly convert .dxf files into .tool files (OSAAP proprietary file extension). Please send us a clean .dxf file (polylines are all joined and closed).
Only .tool files, can be dragged and dropped onto the layout in our software. Once we convert your .dxf to a .tool you will be able to do the same.
