BVPARAM — Visibility Parameter

Adds a visibility parameter to the block being edited.

• Command: BVPARAM · Global name: _BVPARAM

Adds a visibility parameter to the block being edited in the Block Editor and defines its states. A visibility state shows or hides a set of the block's objects; when inserting the block, the state is chosen from a drop-down. The block becomes dynamic and AutoCAD recognizes it as such.

Usage

1. Open the block in the Block Editor (BEDIT).
2. Enter BVPARAM or click Visibility Parameter on the editor bar.
3. Specify the point for the visibility grip.
4. For each state: type its name and select the objects visible in that state; press Enter to finish the state.
5. With an empty name, and having defined two or more states, the visibility parameter is created.
6. Save the block with BSAVE.

Notes

• At least two states are required.
• Block objects not present in any state are hidden in all of them.
• The active state is the first one defined; it is baked into the geometry for plain readers.
• To discard the changes of an already-inserted dynamic block, use RESETBLOCK.
• Outside the Block Editor, the command only shows a message.
