Is it possible to have only first letter of revision shown in drawing? As now it is for example A-01, where the -01 is the secondary revision. As the second revision is "working" revision it will change a lot. And when the part is finished and sent to production/sub contractor we give it a primary revision. So it is only confusing to have secondary revision in the drawing.
And second question about secondary revisions. Are the revision files actually saved into vault three times if I have revisions A-01, A-02 and A-03 made? And more if I do more secondary revisions? If this is the case, is it possible to clean unnecessary files (revisions) afterwards?
