I tried exporting NX sheet to .dwg file. I faced few conversion error in it.
1. If the dimension present in the sheet is cylindrical dimension it gets converted as BLOCK Reference in a .dwg file.
2. If dimension text is overwritten the overwritten text in .dwg file comes in a wrong manner.
3. The conversion works successfully only when the dimension is set as a vertical or a horizontal dimension.
Please let me know what we can do for it.
You might want to post this question in the NX Design forum. I think it is more likely that the translator experts will see it there.
