Import sheet blank from fusion360

Hi froum,
Ive run into a problem regarding the import of a dxf file in wam. i draw a metalsheet in fusion360 and want to cutout the blank of said part. But wam wont let me import it? there is no error message or anything it just dont appear in the window. i checked the file with a dxf viewer and it seems to be correct. Also loaded a other flat part from fusion (which is a solid and not a sheet part) and it works. has anybody experienced something similar?
thanks in advance,
Sam
