Engineering a Site Model Pipeline Across Five Tools Hinges on Shared Control Points

The article argues that site modeling teams should evaluate the workflow between tools rather than their individual features. It stresses that every project must establish a fixed control point, with datum, coordinate system, and units defined, so separately produced models can be combined. GenAnywhere is described as producing terrain surfaces that keep their identity through edits, which allows grading studies to be versioned inputs. MicroStation is presented as the authoritative geometry store that enforces standards and records changes for auditability. The piece highlights concurrency as the main challenge for CityWeft, where multiple authors edit scenario layers simultaneously.
