Is it possible to record a sequence of actions (Macros) in Rhino?

ByCADbrief Staff

Short Answer

Yes — in Rhino 3D, you can record a sequence of actions by building a macro and assigning it to a button, alias, or keyboard shortcut, most commonly through the Options command. This works well for command-line workflows. Limitation: Rhino does not have a live “macro recorder” that captures every click automatically.

What You Need to Know Before

Warning: Rhino macros only replay command-line input reliably, so commands that depend on mouse picks, viewport-specific clicks, or dialog boxes can fail or stop for user input. A common issue is trying to automate commands that open modal windows instead of using command-line options.

How to Create a Macro in Rhino

  • Command: Options

  • Shortcut: None by default

  • Quick Steps:

    1. Run Options, then go to Aliases or Toolbars in the Options dialog.
    2. Create a new alias or button and enter your macro string using standard Rhino command syntax.
    3. Use options like hyphenated commands where available, then save and test the macro from the command line or toolbar button.

Variables & Settings

  • Key Setting: Use command-line versions of commands, often with a hyphen prefix when supported, to avoid dialog boxes and keep the macro scriptable.

Why it Fails

  • Cause 1 (Geometry): The macro may expect preselected objects or specific object types, but the current geometry does not match the command requirements.

  • Cause 2 (layers/Locks): Objects on locked layers or reference geometry in non-editable states cannot be modified by the macro.

  • Cause 3 (Command/Logic): The macro includes a command that pauses for manual picking, opens a dialog, or depends on screen location, which breaks automation.

Quick Fix & Best Practice

  • Quick Fix: Rewrite the macro using command-line options only, and test each command manually before combining them in one alias or toolbar button.

  • Manager’s Verdict: Use Rhino macros for short, repetitive command sequences and setup tasks; avoid them for complex conditional workflows where RhinoPython or RhinoScript is more reliable.

FAQ

Can Rhino record my mouse clicks automatically?
No, Rhino does not include a full live macro recorder for automatic click capture.

Where should I save a Rhino macro?
The most common place is in an alias or a custom toolbar button.

When should I use a script instead of a macro in Rhino?
Use a script when the workflow needs logic, conditions, looping, or dependable object selection.
