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.
Select objects: Use an object selection method
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.
objects selected
as a 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.
