I am trying to open a .step file I downloaded from online and I am having some issues. I opened the file as usual, and it imports and goes through a 'parsing' phase, and then I am left with a totally blank assembly document. In addition, in the folder that the .step part is in, I am left with the same file name but with a .err file that I am unfamiliar with. If anyone has any thoughts please let me know. I am assuming that the part is not corrupted as I received it directly from a supplier, but I have attached it anyways.
