xNURBS announces the availability of Version 5.113 and V4/V5 customers can get a free upgrade to V5.113. V5.113 includes a number of enhancements. The most important improvement is that V5.113 significantly reduces the deviation, and for some models, the deviation achieved by V5.113 can be easily 10 times smaller compared with the previous versions. The following is a short answer of "why xNURBS".

Key Features of xNURBS:

  • Unlimited capacities for solving NURBS: Its optimization algorithm can solve virtually any NURBS surface in a matter of milliseconds (regardless of how complex the constraints are.).

  • High-quality surfaces: For a given set of constraints, xNURBS’ optimization algorithm uses energy-minimization method to generate the smoothest NURBS surface among all possible solutions. The generated surface quality is outstanding.

  • xNURBS is one super powerful NURBS tool that fixes virtually all surfacing issues for existing CAD software.

  • Easy-to-use: It uses one simple UI for all kinds of NURBS modeling.

  • Super robust: xNURBS is rock solid and works flawlessly. 

  • Native CAD surfaces: xNURBS is based on NURBS, i.e., the native CAD surfaces, which can be directly used for any CAD modeling operations without any geometry translation.

The Master Parametric Design in Architecture of UPC School in Barcelona is a unique opportunity to critically review computational design towards a more challenging and self-demanding commitment to environmental constraints.

MPDA is an international program that seeks to teach and explore technology efficiency. It is oriented to the integration of computational tools and digital manufacturing technology in building systems and architectural design. 

MPDA focuses in:
  • Design and optimization of lightweight building systems, mainly through form-finding processes, including tensile architecture
  • Generation of efficient form by efficient means: guiding computational thinking and tools to the simplification of processes and material efficiency
  • Integration with professional workflows and industrial standards, although keeping a wide space for experimentation, research and industry-oriented innovation
This 60 ECTS one-year intense master's degree offers a comprehensive approach training in advanced architectural creation, oriented to efficiency in buildings and commitment to the environment. The course opens with practical digital and physical workshops on parametric software, geometry and numerical control machines, aimed at solving real problems in complex architectural design. The second semester explores real applications through performance-driven design aiming to create interaction and synergies between parametric design and other disciplines such as BIM, urban design, planning, construction, structures, installations, services and climate to obtain more efficient and sustainable results.

It's taught in English at the UPC Barcelona Metropolitan School of Architecture where its Model Workshop, Digital Laboratory and Technology and Innovation Research Team CODA support students to explore all the possibilities of parametric design. Students will benefit from a Rhinoceros license during the master, apart from intensive workshops on the most powerful specific plugins and topics: Kangaroo2, Octopus, Karamba, K2Eng, Kiwi3d, Millipede, Honeybee, among others. The program is well known for its intense series of lectures and workshops with internationally leading experts on computation and construction.

MPDA2022 is Blended learning: 10 months online and 1 stage phase of 1 month intense Barcelona Experience

Register now for an information session that will be held at 02:30 PM CET on Monday 28-06-2021.

The chair for Computing in Architecture, led by Tenure-Track Prof. Thomas Wortmann at the Institute for Computational Design and Construction (ICD) at University of Stuttgart, invites applications for two open positions.

The positions are associated with the Cluster of Excellence Integrative Computational Design and Construction for Architecture (IntCDC) and offer the opportunity for a (publication-based) Ph.D.

Grasshopper skills are a must, skills with C# and/or the Grasshopper – Archicad Live Connection preferred.

This video (tutorial) shows how to work with the VisualARQ Grasshopper styles (VisualARQ objects driven by Grasshopper definitions) in Revit running VisualARQ inside Revit.

This connection lets you work with the VisualARQ parametric objects directly in Revit, which are generated as Revit’s Furniture object types.

This workflow is possible with the VisualARQ Grasshopper components, which let you retrieve the geometry and data of VisualARQ objects and connect them with the Revit components, (available in Grasshopper with the Rhino.Inside tool), and thus regenerate all geometry and data live in Revit, as native Revit Furniture object types.


The "Obsidian Rain" pavilion is one of the main attractions of the 17th International Architecture Exhibition, which was opened to the public on May 22nd.
In this opportunity, the exhibition deals with the theme "How will we live together?", which brings many interesting and multidisciplinary collaborations. 

The "Obsidian Rain" pavilion is a non-standard project designed by Cave_Bureau, using a combination of technologies: FEM structural analysis, Parametric Design, and Augmented Reality. The result is simply amazing and it´s located at the entrance of Biennale Gardens. 

Inside the installation, the ceiling of the cave is created by 1686 Obsidian stones hung on steel ropes with different lengths. The scope is to recreate the entrance of the cave that was laser scanned.

Grasshopper was one of the main tools needed to make this project happen:

"The interoperability between the structural analysis software (RFEM) and the algorithmic modeling software (Rhino + Grasshopper) was crucial. This synergy allowed the efficient management of a large amount of data through an algorithm that updated the FEM model during the various modifications and made it possible to extract the lengths (all different) of the 1686 cables sorted by rows".
