BAUTHORPALETTE command in AutoCAD : Opens the Block Authoring Palettes window in the Block Editor

If you need to create or edit dynamic blocks in AutoCAD, the BAUTHORPALETTE command and the Block Authoring Palettes are essential. This guide explains what BAUTHORPALETTE does, how to use it step‑by‑step, common causes when it doesn’t work and how to fix them, alternative workflows, practical tips, and a FAQ to answer common follow‑ups.

What is BAUTHORPALETTE?

BAUTHORPALETTE is an AutoCAD command that opens the Block Authoring Palettes inside the Block Editor. The Block Authoring Palettes provide quick access to block authoring tools such as Parameters, Actions, Parameter Sets, and Visibility controls—tools used to create and modify dynamic blocks.

  • The command name: BAUTHORPALETTE
  • Purpose: Opens the Block Authoring Palettes window inside the Block Editor
  • Typical use: When creating or editing dynamic blocks (using BEDIT / Block Editor)

Where the Block Authoring Palettes appear

  • When you open a block with BEDIT (or use the Block Editor through the ribbon), the Block Editor environment loads. Inside that environment, running BAUTHORPALETTE displays the palettes docked to the side, containing:
    • Parameters (e.g., Linear, Polar, Rotation)
    • Actions (e.g., Move, Array, Visibility)
    • Parameter Sets (predefined combos of parameters and actions)
    • Other authoring tools used to test or manage dynamic blocks

How to use BAUTHORPALETTE (Step‑by‑step)

Follow these steps to open and use the Block Authoring Palettes to create or edit dynamic blocks:

  1. Open your drawing in AutoCAD.
  2. Enter BEDIT (or click Modify > Block Editor > Block Editor) and press Enter.
    • Select the block you want to edit, or create a new block for authoring.
  3. With the Block Editor active, type BAUTHORPALETTE and press Enter.
    • Or: On the Block Editor ribbon tab, click the Authoring Palettes button if available.
  4. The Block Authoring Palettes window appears (usually docked on the left or right).
  5. From the Parameters palette, drag a parameter (for example, Linear Parameter) onto your block geometry to establish control points.
  6. From the Actions palette, drag a matching action (for example, Move or Array) and then click the parameter grips to link the action to that parameter.
  7. Use Parameter Sets to insert common combinations quickly (e.g., Stretch + Distance).
  8. Test your dynamic block using the Test Block button (found in Block Editor ribbon) to confirm behaviors.
  9. Save changes and exit the Block Editor by clicking Save Block / Close Block Editor or by typing BCLOSE and saving changes when prompted.

Example — Before and after:

  • Before: Block is static — no grips or automatic behaviors.
  • After: Block has parameters and actions — grips appear and the block behaves dynamically (stretch, rotate, visibility states, etc.).

Common problems — Why BAUTHORPALETTE sometimes doesn’t work (and fixes)

If BAUTHORPALETTE doesn’t open or the palettes don’t appear, check these common causes and fixes:

  • Problem: You ran BAUTHORPALETTE outside the Block Editor.

    • Fix: Open the Block Editor with BEDIT first. BAUTHORPALETTE is intended for use inside Block Editor.

  • Problem: The palette is open but off-screen or hidden (multi-monitor or changed screen layout).

    • Fix: Reset palette position: type BAUTHORPALETTE to attempt reopen; if invisible, reset workspace or use Windows shortcuts (Win + Arrow keys) to bring the window back. You can also use the command to reset UI layout or delete/rename the AutoCAD profile to restore defaults.

  • Problem: Working in AutoCAD LT (or other limited versions) where Block Editor features are restricted.

    • Fix: Verify your product supports dynamic block authoring. AutoCAD LT usually lacks the full Block Editor and therefore BAUTHORPALETTE may be unavailable. Use full AutoCAD for block authoring.

  • Problem: Workspace or ribbon customization hides the Block Editor tools.

    • Fix: Switch to a default workspace that shows the ribbon (e.g., “Drafting & Annotation” / “3D Basics”) or restore the workspace using Workspace Switching.

  • Problem: Corrupted user profile, tool palettes, or UI cache.

    • Fix: Reset AutoCAD to default settings (use the “Reset Settings to Default” in the AutoCAD Start menu or recreate your user profile). Repair the AutoCAD installation if UI elements remain missing.

  • Problem: System variables or disabled features preventing palettes from showing.

    • Fix: Ensure palettes and docking are enabled. Use commands like TOOLPALETTES (for tool palettes), and ensure display drivers are updated. Run REGEN if display artifacts appear.

  • Problem: Palettes open but controls inside are grayed out.

    • Fix: Ensure the block is active for editing and that you’re in the correct editing context. If editing an xref block, you may need to edit the source drawing.

Alternative commands and methods

If BAUTHORPALETTE is unavailable or you prefer another workflow, consider these alternatives:

  • BEDIT: Opens the Block Editor (you can access authoring palettes from the Block Editor ribbon).
  • Use the Block Editor ribbon (Block Authoring panel): Click Authoring Palettes there to show the same tools without typing the command.
  • Parameter Sets and Actions from ribbon: Insert parameters and actions directly from the Block Editor ribbon groups.
  • DesignCenter (ADCENTER): For browsing and inserting existing dynamic blocks from other drawings.
  • Tool Palettes (TOOLPALETTES): Store and reuse dynamic block definitions and properties for easy insertion (complementary, not identical functionality).
  • If you cannot author dynamic blocks (e.g., AutoCAD LT), consider creating blocks in full AutoCAD, then using them in the LT environment as static or pre-defined dynamic blocks (if compatible).

Tips and best practices

  • Always work inside Block Editor (BEDIT) before running BAUTHORPALETTE—the palettes are designed for that environment.
  • Pin the Block Authoring Palettes so they remain visible while you edit.
  • Use Parameter Sets to speed up creating commonly used combinations.
  • Test regularly with the Test Block tool to validate dynamic behaviors before saving.
  • Save frequently and keep a backup copy of your block definitions.
  • Create a custom alias (e.g., add a command alias for BAUTHORPALETTE if you use it often) via acad.pgp for faster access.
  • Document your dynamic block parameters and actions for other users in your CAD standards.
  • If palettes are off-screen after disconnecting a monitor, use Windows window management shortcuts or reset the workspace to bring them back.

FAQ

What exactly does BAUTHORPALETTE open?

BAUTHORPALETTE opens the Block Authoring Palettes within the Block Editor, giving access to Parameters, Actions, Parameter Sets and other dynamic block authoring tools.

Can I use BAUTHORPALETTE in AutoCAD LT?

No — AutoCAD LT typically lacks the full Block Editor used to author dynamic blocks. If you need to create or extensively edit dynamic blocks, use full AutoCAD.

Why does BAUTHORPALETTE do nothing when I type it?

Most likely you’re not in the Block Editor. Open a block with BEDIT first, then run BAUTHORPALETTE. If you’re already in the Block Editor and nothing happens, the palette may be off-screen or your workspace/UI may be corrupted — try resetting workspace or AutoCAD settings.

How do I restore the authoring palette if it’s off‑screen?

Try toggling BAUTHORPALETTE again, switch workspaces, use Windows shortcuts (Windows + Left/Right Arrow) to move the window, or reset AutoCAD to default settings. Reconnecting the second monitor or deleting saved UI layout files may also help.

Is there a keyboard shortcut for BAUTHORPALETTE?

There is no default single-key shortcut, but the fastest built-in method is to type BAUTHORPALETTE and press Enter. You can create a custom alias (in acad.pgp) or a macro to call it with a shorter command.

What’s the difference between BAUTHORPALETTE and TOOLPALETTES?

BAUTHORPALETTE opens the Block Authoring Palettes used to build dynamic block parameters and actions inside the Block Editor. TOOLPALETTES opens the tool palettes for inserting blocks, tools, and content into drawings—useful for deployment but not for authoring dynamic behaviors.

How can I make the Block Authoring Palettes appear automatically when I open the Block Editor?

Use the Block Editor ribbon and ensure the Authoring Palettes button is visible; pin the palettes before closing so the saved workspace retains their state. If needed, create a script or macro that launches BEDIT followed by BAUTHORPALETTE.

My action/parameter commands are grayed out — why?

You may not be editing an editable block instance (for example, trying to edit an xref or a block in a locked state). Make sure the block is opened for editing in the Block Editor and that you have proper permissions and the correct drawing context.
