"rectangular space" in layout

Hi all,
Someone used some way to draw a lot of "rectangular spaces" in paper space.
I think his/her purpose was to cover the entities beneath text so that
people could read the text. Those "spaces" are inside a viewport, so they
actually covered parts of the plan shown by this viewport. As text are
removed, I want to show back the parts that was hidden by those "spaces".
Could anyone help me to remove those "spaces"?
As I couldn't select them, I have no idea of what they are. Your
step-by-step instructions may be necessary.

TIA,
el

 

Not knowing which release of AutoCAD you are using (or which it was created with)... Hopefully you have Express Tools.

See if you have any layers turned off or frozen...

Try typing in TFRAMES (As I assume they are WIPEOUTS)
or
Try typing in TEXTUNMASK and select the MTEXT (Assuming they might be TEXTMASKs)

 

Thanks Tracy. TFRAMES is the magic command that I needed.
Thanks again.
