At present, there are still many problems in the use of Revit, which is the mainstream design software of BIM technology. Combined with practical cases, this article conducts in-depth research on the problems encountered in exporting PDF, DWF, and DWG formats during the final stage of design, and explores various solutions, so that the exported PDF and DWF-format drawings can meet the requirements of direct submission for drawing review, printing, or archiving. For the most challenging CAD export problem considered by various design institutes, this article also proposes practical and feasible optimization solutions, which can basically achieve the expression effect of two-dimensional drawing, greatly improving the drawing efficiency and saving time.
