From Features

Topology Finding of Patterns for Structural Design (Oval, 2019)

RV2pattern_from_features is based on the compas_singular package. For more information on the package, please check out its online documentation.

RV2pattern_from_features is in early stages of development, and may not always result in suitable solutions. The contents of this feature are subject to change, and will be improved in future releases of RV2.

Using the RV2pattern_from_features command is a powerful and an effective way to generate quad mesh patterns from complex or irregular boundary conditions and point features, such as the British Museum Great Courtyard Roof.

Following the boundary

The first example takes into account only the input surface to produce a pattern align with the boundaries. This aspect is important in funicular form finding in the case of non-supported boundaries.

Select a NURBS surface

No optional point features here

Set a target length of 5 for the mesh edges

Set a number of iterationsof 50 for constrained Lapalcian smoothing

With poles around point features

The second example also takes into account point features on the surface to include pole points in the pattern. The point features at the corner can integrate local concentration of thrust. The other point features can integrate point loads or nodal supports. All these aspects are important to design a suitable pattern for funicular form finding.

Select a NURBS surface

Choose some point features on the boundary and on the surface

Set a target length of 3 for the mesh edges

Set a number of iterations of 50 for constrained Lapalcian smoothing\
