Follow-up to last hour's #45/#46. After the title fix, the drawing number box still showed "----" because it "seems to read the drawing tab's own Part number property, not the part's" (#52). #53 answers how a drawing fixed in Onshape gets back into LUNA. "Until now, the only way was to attach the file by hand in LUNA." It adds an UPDATE FILES button that uploads the next revision. A HISTORY tab was added in #50 and removed in #51 within 15 minutes. Neither #52 nor #53 was tested against real Onshape or LUNA.
