At the Command prompt, creates a block definition from selected objects.
If you enter -block at the Command prompt, the following prompts are displayed.
Names the block. The name can have up to 255 characters and can include letters, numbers, blank spaces, and any special character not used by the operating system and the program for other purposes if the system variable EXTNAMES is set to 1.
By redefining a block, you automatically update all references to that block. Attributes attached to existing block references remain unchanged in the drawing. However, new insertions of the block do not prompt for attributes unless the attribute definitions are included in the new block definition.
Use the ATTREDEF command to update the attributes of an existing block insert. (Not available in AutoCAD LT.)
The point specified as the base point is used for subsequent insertions of the block. Typically, a base point is the center of the block or its lower-left corner. The base point is also the point about which you can rotate the block during insertion. A block with 0 rotation is oriented according to the UCS in effect when it was created. Entering a 3D point inserts the block at a specific elevation. Omitting the Z coordinate uses the current elevation.
Creates an annotative block.
Specifies the mode for object conversion.
If you enter yes, the block’s orientation in paper space viewports will match the orientation of the layout.
Selects the objects for the block.
Lists the block names in the text window.
In the list, external references (xrefs) are indicated with the notation Xref: resolved.
In addition, externally dependent blocks (blocks in an xref) are indicated with the notation xdep: XREFNAME, where xrefname is the name of an externally referenced drawing. The following terms are used in the list:
