When you bring an underlay into an AutoCAD -- an image, DWF, DGN, or PDF -- it comes with a frame or border around it. (Clipped references, DWG or otherwise, have frames too.) You have three choices for this frame's visibility and plotting:
- 0 -- Off. You can't see the frame, so it won't plot, but you can't select the underlay or modify it either.
- 1 -- On. The frame plots, and you can use it to select the underlay, resize it, move it, etc.
- 2 -- On, but non-plotting. The best of both worlds. You can see the frame, and use it to select and modify the underlay, but it won't plot.
Each reference/underlay type has its own frame variable.
- IMAGEFRAME (Default: 1)
- DWFFRAME (Default: 2)
- DGNFRAME (Default: 0)
- PDFFRAME (Default: 1)
- XCLIPFRAME (Default: 2)
