This is the fourth release of my plug-in which enables you to create loops in Grasshopper. The basic workflow relies on two main components :

  • Loop Start

  • Loop End

Where Loop End sends data back to Loop Start.

There are probably still some bugs, so save your work twice before using Anemone.


  • 0.4 Fourth release

    • Two new loop modes added - fast and internalized.

    • Cleaned up the interface of the classic components.

    • Added time buffer.

    • Each loop mode has now an optional timeout value, preventing the loop to run for too long.

  • 0.26 Third release

    • "Unable to restart" bug fixed.

    • "Browse history" component added.

    • Refreshed icons.

    • Changes under the hood (preventing potential bugs)

    • Loop Start counter output caused Grasshopper to slow a bit, now it won't draw the counter value as output name.

    • Minor bugs fixed.

  • 0.2 Second release

    • Backward compatible with the GH 0.9.0014

    • ​~60% of the code rewritten.

    • Added support for multiple data streams (use ZUI).

    • "While" loops made possible with a new "Exit" input in Loop End. Set to True to exit the loop.

    • Double click the Loop End to pause/unpause the loop.

    • Changed layout for clarity.

    • Renamed "Steps" to "Repeats".

    • Now "Repeats" do not restart the loop when changed. Therefore you can always increase the loop count without wiping the data.

    • Trigger input supported only one trigger value, fixed.

    • Probably faster.

    • Lots of bugs fixed...

  • 0.1 The first release

I have tested this project, but it is the first release and it might contain still bugs. Please use it "as is", it does not come with warranties. I spent a lot of time developing the logic and implementing it, please give credit where credit is due.

To install:

  • In Grasshopper, choose File > Special Folders > Components folder. Save the gha file there.

  • Right-click the file > Properties > make sure there is no "blocked" text

  • Restart Rhino and Grasshopper
