Which systems exist for parametric design?

Several software platforms have become standard in the world of parametric design. Grasshopper, an extension of Rhinoceros, is widely used by architects to model complex geometries, while Dynamo for Revit allows engineers and designers to automate processes directly within BIM workflows. Alongside these, proprietary platforms are emerging that focus less on form-finding and more on performance-driven outcomes, such as daylight, energy use, or cost efficiency. The main differences between these systems lie in scalability, accessibility, and how closely they match real estate workflows. Grasshopper and Dynamo are flexible but often require advanced scripting knowledge, which can be a barrier for non-specialists. OMRT developed its own platform to close this gap, enabling real estate professionals to work with parametric insights without needing coding skills. This makes it easier for developers, municipalities, and investors to use parametric design as a decision-support tool from the earliest project phases.
