Drawings placed into Model views are external files (such as DWG, PDF files and image files).
Drawings can be placed into any model view except a 3D Window or a Schedule view.
A placed drawing retains its source file information and can be updated. You can customize the size, title and framing options for your drawings. (Figures, in contrast, do not have these features.)
Placing a Drawing into a model can be useful if, for example, you receive a standard roof structure detail drawing from a manufacturer in PDF format. You can place this PDF document as a Drawing into your Detail window, add your own alterations or markups as needed, then place it as a modified detail onto a Layout.
Similarly, an external DWG file can be placed as a Drawing into your model as a vectorial drawing. This is a simpler solution for accessing DWG files in Archicad, as opposed to attaching the DWG file as an XREF.
