Reference drawings

A reference drawing is a 2D drawing imported from an external DWG, DWT, DWF, DWFx, DXF, or DGN file that is attached to a work view, drawing view, or diagram, and serves as a visual aid when inserting 3D design objects, 2D diagram symbols, or 2D annotations. Reference drawings can be resized, repositioned, and customized by adjusting line weight and color, without modifying the original drawing. Reference drawings may maintain a link to the original file, or break the link during import, storing a copy of the original drawing in COS. In both cases, if modifications are made to the original, the reference drawing can be updated by reloading, and unnecessary reference drawings can be hidden or removed entirely.
