C2. Materialise Membrane
create cutting patterns of the textile shuttering and unroll and align to the CNC-workspace
The textile shuttering (or membrane) must be patterned into developable strips to adapt to complex double-curved geometries. It is the same principle as flattening the peel of a clementine. The cutting pattern is limited to the alignment with the cable-net, size of the fabric rolls, and size of the workspace of the CNC-cutting machine.
Objectives
You will learn how to prepare the textile shuttering for fabrication taking into account fabrication constraints. For this, you will learn how
to generate a cutting pattern on the 3D mesh by stripping and splitting a mesh datastructure,
to unroll a 3D mesh strip into a planar mesh strip with frame-to-frame transformations, and
to generate the CNC-cutting line using polygons and transformations with a bounding box
Procedure
This task is structured into three main steps:
Strip the form-found mesh into new strip meshes along parallel edges:
2. Unroll a mesh strip onto the XY-plane by frame-to-frame transformations:
