Set the Default Application to open DWG Files

While it’s certainly possible the SDI variable was changed from its default value of 0, the more common cause to drawings opening in a new session of AutoCAD is related to the application associated with DWG files on your computer. Although it might seem logical to set AutoCAD as the default program for DWG files, doing so will cause every drawing to open in a new session of AutoCAD. Instead, the default program associated with DWG files should be the “AutoCAD DWG Launcher”.

To set the “AutoCAD DWG Launcher” as the default program for DWG files:

1. Locate a DWG file in Windows Explorer.
2. Right-click on the DWG file and select Properties.
3. On the General tab of the Properties Dialog, select the “Change” button next to the “Opens With” property.
   

   

   Windows File Properties Dialog

4. Locate “AutoCADDWG Launcher” within the “Opens With” dialog, and click OK.
   

   

   Windows Open With Dialog

Double-clicking DWG files from Windows Explorer should now open drawings in a single session of AutoCAD.

How to remove Frames around blocks

If your drawings are showing frames around blocks and clipped xrefs
and you need to remove it try

FRAME = 0

AutoCAD Help says:

Turns the display of frames on and off for all external references, images, and DWF, DWFx, PDF, and DGN underlays. The FRAME setting overrides the individual IMAGEFRAME, DWFFRAME, PDFFRAME, DGNFRAME, and XCLIPFRAME settings.
0 The frame is not visible and it is not plotted

1 Displays the frame and allows it to be plotted

2 Displays the frame but keeps it from being plotted

3 The setting varies for all attached images, underlays, and xrefs

or another solution

The possible reason: It’s come from any regular block or dynamic block after they got xclipped. In 2000 – 2010 versions the xclip frame is invisible and uneditable but from 2011 you can set it visibility via the XCLIPFRAME variable and grip edit / invert it.

XCLIPFRAME = 0 to turn off.

That’s a clip boundary. The benefit of leaving it on is that you can edit the clip from the boundary grips, and invert clipping side (likes making a hole inside your block, in your case, the boundary is larger than the block extent so when you invert it, you see nothing).
