Sorry to ask a question that has already been answered before but the answer was not enough for me.
I'm looking to transfer a very large Autocad 3D file to Solidworks. After exploring several forums, several tutorials and several books, I don't understand why, when I click on the drop-down menu at the top left, the export formats that are offered to me do not correspond to those that are supposed to be there according to the books, tutorials, forums...
Let me explain: I saw that it was possible to export your autocad documents in different formats, including the IGES (.igs), ACIS (.sat) and STEP (.step) formats. However, my Autocad 2013 only offers me the .pdf, .wmf, .bmp, .dwg, .dng V8 and V7 formats. I don't really understand why other formats are inaccessible to me??? Have these file conversions disappeared on the 2013 version? Did I make a mistake?
