Hello Michael,
sorry for my delay.
I just converted into the different formats of you refined version and sent it to the manufacturer.
Tommorow I may tell you more...Thank you very much, best regards...

Hi Michael,
cannot find your message in the inbox...so here...the only format the cnc-maker was able to read is the .iges
He has many opportunities to read and translate files...but step sat etc didn´t work.
Not sure whatis his cnc-software exactly...he works with catia, and all the other similar candidates as far as I know.
Ok - seems to work with iges...best regards...

Hi Mala, I'm glad that IGES format worked ok. Over here I tried the STEP and SAT files with 5 different programs and it imported ok into all of them. It would be good to know exactly what programs and what versions they are trying to use and if they aren't trying with more than one program you may want to find another shop.

- Michael

try to find it out...
