RE: AutoCAD R14 Tip

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have always followed the steps of creating a Block and then using Wblock
to save it to a disk. When I have done this, the file was not copied to the
disk with a thumbnail graphic. If I later retrieve the file by inserting a
file, I could not see the thumbnail.
Maybe this is a change made to Release 14. I learned of the shorcut on the
Autodesk Web site under their Tips & Tricks section. You might want to check
it out to verify that it is as I reported it. The tip seemed to imply that
it did not perform the same as the original steps using block and then
Check it out and then let me know - or let me know if they changed the
Wblock command in R14 to save thumbnails with the file.

|W,         *WBLOCK
|There's also the BLOCK command (Acad.pgp alias = -B) and an AutoLISP

|The WBLOCK command has always allowed you to bypass the BLOCK command.
|Command: WBLOCK
|[Specify new DWG file name in dialog]
|Block name: [press ENTER to skip specifying an existing block name]
|Insertion base point: [pick point]
|Select objects: [do so]
|>> The final advantage to this is that it will automatically save a

|WBLOCK saves a thumbnail on my system.
|>> The objects are saved as blocks and also wblocks. <<
|The WBLOCK command creates a new DWG file out of the objects, but does
|not create a block definition in the current drawing. If you insert
|the new DWG file back into the current drawing, then AutoCAD creates
|the block definition in that drawing.
