I've just done what GeorgeB did.
Selected a range of cells in Excel....right click and select copy.
In AutoCad, select edit and then paste.
Ctrl-c and Ctrl-v also worked for me.
I have AutoCad 2006 and 2007 LT.
But with this one application any version is it still an Interactive Excel Data ?
Once it's placed, does it still update once you have to change the Excel sheet and it will refresh to a drawing?
Maybe I've totaly wrong with this following statement and will just state this from case history here's how it is!
Right, But for those reading along at home the key part is that two different file format are merged. What a reader might not or don't realize is that this placement is just that a "snapshot" of the Excel sheet, or at least it was!
Be it as simple as to the date and time that it was placed inside the ACAD file,(that's it) It will display and print, but all excel aspects are lost by this placement, once placed it will not be editable from inside the the cad file once the spread sheet. It's Excel, edit, properties, even the data fields is gone, once brought in.
As noted, software can be written from with-in Acad that will make it interactive, its not part of the base package of ACAD and is additional software, or write a program.
The Bigger packages do have there own programing languages and even level of programing which will allow this.
I feel that the big CAD software packages other than selling there own additional software packages, have "handicapped" the average to above average users trying to tie in such programs as excel or the like.
