DSTV files

Hello,
I have a problem with DSTV file import. Part`s imported from DSTV file shows only hole without contur. I attached 2 photos for highlighting the problem, in the first picture is DSTV file imported in SheetCam and in second picture is the original DSTV file. Also attached the original NC file.
Another question its about I-BEAM module, it will be founded in later releases?
Final question, how i use SheetCam to do marks on plates, parts etc?
Have a good day!
