Issue:

By default, inserted reference underlays and raster images have borders (frame). How to set whether these borders are displayed or not?

Causes:

In ZWCAD, the graphic elements that have borders include DGN underlays, DWF underlays, raster images, PDF underlays, clipped DWG references, and wipeout frames.

Whether these borders are displayed or printed is controlled by the system variables DGNFRAME, DWFFRAME, IMAGEFRAME, PDFFRAME, XCLIPFRAME, and WIPEOUTFRAME respectively.

At the same time, ZWCAD provides a unified border system variable FRAME.

Solution:

Input the command FRAME, press Enter, and set the value as 0, all the borders will not be displayed or printed.

If you want to hide just some objects' borders, please keep the FRAME as the default value 3, and set the corresponding system variable to control it.
