UCS in the Block Editor
Within the Block Editor, the origin of the UCS icon defines the base point for
the block. You can change the base point for the block by moving the geometry
relative to the origin of the UCS icon, or by adding a base point parameter.
The UCS command is disabled in the Block Editor. Keep the following in mind:
■ While you can assign parameters to an existing 3D block definition, the
block reference cannot be edited along the Z axis.
■ While you can add actions to a dynamic block that contains solid objects,
you can't perform solid editing features within a dynamic block reference
(for example, stretch a solid, move a hole within a solid, and so on).
NOTE The Command window should be displayed in the Block Editor, as it displays
prompts for many aspects of creating dynamic blocks.
