Yes, which is very confusing. Using "save as" implies transforming the current drawing into something else.
This functionality belongs to exporting, or printing in case of pdf. Same for .stl format used by 3D-printers. I really want to export a stl file, not convert the drawing to that. Any time the user wants to make an exported file he has to close the new stl file drawing and re-open the tcw.
Please, add a menü "file -export" and put some used file formats therein.
