Creates a waffle structure from a volume.

The component can handle multiple holes and is very fast!

Waffle open surfaces quickly e.g. by using the offset or extrude component (see examples).


Create a radial waffle structure from a mesh.


Creates a layer model from a volume.

You can specify a border to create a hollow. The border defines the minimum overlapping of the parts (e.g. for glue)


Creates a section model from a volume.

You can specify the section planes.

Note: BBWaffle, BBRadial, BBLayer and BBSection support only meshes. I droped Brep support because of the very low performance and stability. Use Grasshoppers mesh tools to generate meshes from Breps (see examples).


BBOffset, BBUnion, BBDifference, BBIntersection, BBXor:

Fast offset and boolean operations for linear polylines.


Represents text with a single line font for labeling and engraving.

It uses a self made font engine which works very fast and accurate. All characters consist of lines and arcs. No Nurbs, no duplicate curves! Perfect for fabrication!

You can define location, orientation and size of the text. Choose between normal and bold font.

The component supports the following characters:

Basic Latin:

Extended Latin:


Special Characters:

Greek Letters:

Rhino Commands:

Preview in Rhino:

Automatic alignment:

Drag the gha file on to your grasshopper window. You will find the new components in the „Bowerbird“ tab.

Please add support for RhinoWIP MacOS.

Are there some rules to follow when using the BBSection tool? i.e. do the section planes need to be positioned in a certain way?

I only get partial slits, not slits that go half way through each section piece.

You can use the boolean operations of grasshopper to build such things.

The problem is that they are quite slow/inaccurate. That's why I use meshes and planes to get better results.

The aim of Bowerbird was to create a tool that allows you to create waffle sturctures rapidly. The components should give you a general solution that works in most cases.

Of course there are a lot of special cases where you want to have more options or create custom waffle systems. It's impossible for me to integrate them since they probably will work only for specific problems. If the waffle structure itself is part of the design then it should also be the task of the designer to specify these details.

I add the BBSection component and the boolean operations so that people can create their own systems. Also the source code is public.

Unfortunately studying keeps me very busy at the moment so I don't manage to improve the pluging an answer to all questions.

I hope my plugin can still help you sometimes.


btw: please post such questions in the forum and not on the comment wall

You can use the "BBSlice"-Component:

Comment by martyn hogg on July 2, 2015 at 1:50pm

the edges would just fall off :)

Comment by Thomas on March 7, 2015 at 2:23am

Use a reversed base plane (z-axis negative) to reverse the slits.

Use the Slice component to define a custom slice pattern via planes.

Please post your questions in the bowerbird forum!

Hi is there a way to reverse the slids so they go from top to bottom instead of bottom to top? And make a certain Y or X follow a curve instead of just X or Y?

Hi Tim! Thank you for the comment. I made a mistake when I changed the font format. Sorry for that! I have readded the letters in the last release (0.6.1).

Comment by Tim Nøhr Elkær on October 16, 2014 at 3:09pm

Hi Thomas. I'm still missing the æøå (miniscule) letters in the current version at GitHub. I think I had them last year, but now they are gone.

Comment by Thomas on July 5, 2014 at 2:12am

You can use the base plane parameter to change the direction of the operation. The x/y layers are always orthogonal.

For the future: Please post your questions in the bowerbird forum instead of the comment wall!
