Overview ParaCloud is a 3D Pattern Modeler. It was created to provide a simple approach for generating complex and rich 3D models without resorting to scripting of any kind. ParaCloud is created by designers, for designers. It was created following more than 10 years of research in the field of design computation, making generative design more approachable than ever.

e. Parametric control ParaCloud GEM includes smart face tools that allow controlling the face behavior of both the main and offset meshes. Each face acts as a container for the component geometry and provides a parametric design operator that controls its behavior. The behavior can be related to target points, direction, fixed or random values. f. 3D printable output : ParaCloud GEM introduces tools for creating unfolded components layout and Ribs and components bleeding – developed for enhancing rapid prototyping processes. The geometry created with gem from watertight components is 3D print ready. g. Works with most CAD softwares: Add generative power to your CAD system. GEM works with any software supporting OBJ format including SketchUp Pro, Rhino, 3DS Max, Maya and many more.

Press the
button to open the ParaCell layout
Define a rectangular panel using an Edge Surface that connects nodes according to paired points (n,-n). Using a position value greater than 1 projects the node out of the cellular array. Using diagonal pairs allows for the overlap effect of the rain screen. The panels created for both directions to accommodate all options, using two position values to allow for a staggering effect for each direction (total of four panels).

CAD Logic iii Mirrored loft components – Second pair Create another pair of loft components, mirrored along the horizontal axis of the sampling cube front face. Populate the second pair over the ridge line. The components are tilted and extended outside from the sampling cube to allow overlapping between adjacent panels. Using two different position values (columns K and O) connected to driving parameters, controls the extension dimension of the panel and allows for the overlap of the rain screen.
