Think out of the box

Using the powerfull tool set of Biber join advanced designers and fabricator and realise your most complex projects.

Realize the unimaginable

Design and build complex geometry from planar sheets is now possible in a work frame that includes both design and fabrication data.

The workflow

Biber offers a simple yet effective workflow to build the parts from geometries with planar sheets. Both Mesh and Brep can be used as input geometry. The geometry first is converted to a special form so called Planar Poly Surface (PPS). This format of geometry is specific to Biber which stores the relations between Faces, Edges and Vertices and carries the tolerances which are used to test the planarity of faces and proximity of the vertices.

From each face in the input PPS a part is created. The geometry of each part is constructed taking into account the adjacent parts along the edges and vertices. In order to perform this complex task Biber takes the user input with regards to all components in PPS : Faces, Edges and Vertices. The geometric and topologic information in PPS and user inputs on Shells, Joints and Nodes comes together in an Assembly. The “Biber” assembly is then used to generates the parts or simulate the assembly process.

Once an assembly is successfully created, user can disassemble it. The “Disassemble” component is in fact the main component which takes the most computation power in the entire workflow. After a successful run of Disassemble component , up to three different outputs may be generated. The main output contains the Shell(s) which are used to produce the actual parts. At last user can use “Unfold” to generate the final geometries from each Shell object. The same component allows user to quickly nest the parts into given sheets.

Learn Biber

Using multiple joint types in Biber assembly

In this tutorial you learn how to assign different joint types to different edges in an assembly. We continue from the previous tutorial and add a cap to the box we created before, the edges around the cap are treated using Lap joint. You also learn how to flip the joint about an edge if needed.

Biber edge selection tool, pick edges from grasshopper preview

In this tutorial you learn how to assign different joint types to edges of the assembly just by picking them directly from the viewport.

Parametric Shelves. Change the joint types parametrically.

In this video you learn how to create a fully parametric model of a simple bookshelves. The joints are used in this example are simple Butt joint and Lap joint. You also learn how to join co-planar parts around the non-manifold edges and create larger parts. Use of filters in Biber is essential to achieve a parametric workflow. Filter can select edges automatically using filter rules.

Remove intersection between parts around the corners in Biber

In this video we introduce Node component which resolves the parts around the corners. This component cuts material around the corners as such that they do not intersect each other. This is necessary for the vertices that share facing with no common edge.

Version 1.1.0.0

In this update a new group of components is added to provide various functionalities with regards to building sub-structures. These components can generate additional elements to permanently or temporary support the main parts in the assembly.

The main components of Biber are also improved to handle the curve edges.

Additional utility item is added to enable user to mark the edges so that it is easier to assemble.
