Select Objects If you specify the insertion base point, you are prompted to
select the objects.
The program defines a block using the objects selected, the insertion base
point, and the name provided, and then erases the selected objects from the
drawing. You can restore the deleted objects by entering the OOPS command
immediately after BLOCK.
The insertion base point becomes the origin of the block's coordinate system,
which is parallel to the UCS in effect at the time that you define the block.
When you insert the block into a drawing, its coordinate system is aligned
parallel to the current UCS. Thus, you can insert a block at any orientation
in space by setting the UCS first.
?List Previously Defined Blocks
Lists the block names in the text window.
Enter Blocks to List 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:
User Blocks: Number of user-defined blocks in the list.
External References: Number of xrefs in the list.
Dependent Blocks: Number of externally dependent blocks in the list.
Unnamed Blocks: Number of unnamed (anonymous) blocks in the drawing.
