What Is the Parametric Design Process for GRC Special-Shaped Forms? Algorithm-Driven Digital Practice at Qinglong Group

The parametric design workflow for GRC freeform shapes is a digital creation system based on "algorithmic generation, performance simulation, and data-driven" principles. Its core steps include: form generation (Rhino+Grasshopper), structural form-finding (Karamba), and manufacturing optimization (BIM). Qinglong Group has fully applied this workflow in projects such as the "Dongguan Grass Weaving" facade at the Dongguan Women and Children's Activity Center and the nebula-shaped form of the Shanghai Astronomy Museum: first, design parameters (such as weaving density and curve functions) are input, and the algorithm generates the initial form; then, finite element analysis (stress ≤5MPa) is performed to optimize panel thickness and stiffening ribs; finally, machining data (CNC code) and installation coordinates are output. Parametric design not only improves efficiency but also achieves complex forms that traditional methods can hardly reach.

Form Generation and Algorithmic Control

By defining parameters (such as point, line, and surface relationships), geometric deformation is driven. In the "Dongguan Grass Weaving" project, the Qinglong team wrote dedicated algorithms to translate hand-weaving logic into digital models, generating 2,872 GRC panels with no two identical. Parametric design increased design change efficiency by 10 times.

Integrated Structural Performance Optimization

Using topology optimization technology, weight is reduced by 30% while ensuring strength. Through iterative calculations, we find the optimal balance between form and structure. In a cantilevered form at an art center in Shenzhen, parametric form-finding kept the maximum deflection within L/250.

Seamless Data Integration with Production

Design models feed directly into CNC machines, realizing "design as production". Qinglong Group has established a digital twin system to monitor production progress in real time. The parametric workflow connects the entire chain from concept to finished product and is at the core of intelligent manufacturing.
