hello, it's iva. this site is my portfolio.
Mexico hospital panels
Overview
Textile membrane panels made fully in Rhino and Grasshopper. As an input algorithm takes triangular meshes or surfaces, as output - excels with parts lists, valid closed 3d models of each part, production drawings per each part, part nesting. WIP project in Mexico.

Events
Aichi Nagoya 2026
Designer and installation manager on multiple venues for Asian Olympics 2026. Short time, solutions on the fly, high pressure. On the pictures below you can see a few Grandstands and Turnkey solutions I worked on.

WUF 2025
World Urban Forum Baku. Design, modeling and production of the facades. Extremely short timing, only few days from the beginning of the design process to the final model.

Osaka Expo 2025
Ocean Dome Kangaroo simulation with custom goals. In this project I did not play a big role; But it's for Shigeru Ban, can't go past it.
The simulation you see below is a new dome - continuation of the project, that will be located in France.

Unitize facade system
Overview
Parametric tool for detailing unitize systems or aluminium panels on facades in Revit. System is able create corner units with different angles. Inputs for the algorithm is a sample unit that we want to use, and a facade grid, that we would like to populate with it. Grid can be extracted from Revit curtain walls, provided from dwg or made in Rhino. As an output we get Revit families with uploaded units, scaled and placed to match provided grid. The algorithm creates new family for each unit of different size. Materials and parameters can be applied. Tables with materials can be exported.
