Creating blocks: which interface appears? When the drafter types BLOCK at the command line or clicks the Make Block tool from the Draw toolbar/ribbon, which AutoCAD interface opens to define name, base point, and objects?

Introduction / Context:
Block creation in AutoCAD is typically handled through a dedicated dialog that consolidates the naming, base point selection, object selection, and behavior options. Recognizing the correct interface helps new users avoid confusion with unrelated settings or panels.

Given Data / Assumptions:

• User executes the BLOCK command or selects Make Block from the UI.
• AutoCAD is in a standard configuration with dialogs enabled (not command-line only).
• We are creating a conventional static block (not dynamic parameters yet).

Concept / Approach:
The Block Definition Dialog is the central interface for naming the block, specifying the base point (pick point or coordinates), selecting the objects, and setting options like “Convert to block,” “Retain,” or “Delete.” It is distinct from other interfaces such as BEDIT (Block Editor) for editing existing blocks, and it is not the grid or a generic text box.

Step-by-Step Solution:
Invoke BLOCK or the Make Block tool.Observe the Block Definition Dialog open.Define name, base point, and select objects; confirm behavior options as needed.

Verification / Alternative check:
Try WBLOCK for writing a block to an external DWG; a different dialog appears, confirming that the BLOCK command specifically launches the Block Definition Dialog.

Why Other Options Are Wrong:

• Grid: a display aid, not a dialog.
• Block Text Box: not an AutoCAD interface name.
• None of the above: incorrect because the named dialog exists.

Common Pitfalls:
Confusing BLOCK with BEDIT; BEDIT edits existing blocks, while BLOCK creates a new definition from selected objects.

Final Answer:
Block Definition Dialog
